Abstract

Background

Cardiovascular disease is the most common cause of death globally. Traditionally, centre‐based cardiac rehabilitation programmes are offered to individuals after cardiac events to aid recovery and prevent further cardiac illness. Home‐based and technology‐supported cardiac rehabilitation programmes have been introduced in an attempt to widen access and participation, especially during the SARS‐CoV‐2 pandemic. This is an update of a review previously published in 2009, 2015, and 2017.

Objectives

To compare the effect of home‐based (which may include digital/telehealth interventions) and supervised centre‐based cardiac rehabilitation on mortality and morbidity, exercise‐capacity, health‐related quality of life, and modifiable cardiac risk factors in patients with heart disease

Search methods

We updated searches from the previous Cochrane Review by searching the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (Ovid), Embase (Ovid), PsycINFO (Ovid) and CINAHL (EBSCO) on 16 September 2022. We also searched two clinical trials registers as well as previous systematic reviews and reference lists of included studies. No language restrictions were applied.

Selection criteria

We included randomised controlled trials that compared centre‐based cardiac rehabilitation (e.g. hospital, sports/community centre) with home‐based programmes (± digital/telehealth platforms) in adults with myocardial infarction, angina, heart failure, or who had undergone revascularisation.

Data collection and analysis

Two review authors independently screened all identified references for inclusion based on predefined inclusion criteria. Disagreements were resolved through discussion or by involving a third review author. Two authors independently extracted outcome data and study characteristics and assessed risk of bias. Certainty of evidence was assessed using GRADE.

Main results

We included three new trials in this update, bringing a total of 24 trials that have randomised a total of 3046 participants undergoing cardiac rehabilitation. A further nine studies were identified and are awaiting classification. Manual searching of trial registers until 16 September 2022 revealed a further 14 clinical trial registrations ‐ these are ongoing. Participants had a history of acute myocardial infarction, revascularisation, or heart failure. Although there was little evidence of high risk of bias, a number of studies provided insufficient detail to enable assessment of potential risk of bias; in particular, details of generation and concealment of random allocation sequencing and blinding of outcome assessment were poorly reported.

No evidence of a difference was seen between home‐ and centre‐based cardiac rehabilitation in our primary outcomes up to 12 months of follow‐up: total mortality (risk ratio [RR] = 1.19, 95% confidence interval [CI] 0.65 to 2.16; participants = 1647; studies = 12/comparisons = 14; low‐certainty evidence) or exercise capacity (standardised mean difference (SMD) = ‐0.10, 95% CI ‐0.24 to 0.04; participants = 2343; studies = 24/comparisons = 28; low‐certainty evidence). The majority of evidence (N=71 / 77 comparisons of either total or domain scores) showed no significant difference in health‐related quality of life up to 24 months follow‐up between home‐ and centre‐based cardiac rehabilitation. Trials were generally of short duration, with only three studies reporting outcomes beyond 12 months (exercise capacity: SMD 0.11, 95% CI ‐0.01 to 0.23; participants = 1074; studies = 3; moderate‐certainty evidence). There was a similar level of trial completion (RR 1.03, 95% CI 0.99 to 1.08; participants = 2638; studies = 22/comparisons = 26; low‐certainty evidence) between home‐based and centre‐based participants. The cost per patient of centre‐ and home‐based programmes was similar.

Authors' conclusions

This update supports previous conclusions that home‐ (± digital/telehealth platforms) and centre‐based forms of cardiac rehabilitation formally supported by healthcare staff seem to be similarly effective in improving clinical and health‐related quality of life outcomes in patients after myocardial infarction, or revascularisation, or with heart failure. This finding supports the continued expansion of healthcare professional supervised home‐based cardiac rehabilitation programmes (± digital/telehealth platforms), especially important in the context of the ongoing global SARS‐CoV‐2 pandemic that has much limited patients in face‐to‐face access of hospital and community health services.

Where settings are able to provide both supervised centre‐ and home‐based programmes, consideration of the preference of the individual patient would seem appropriate. Although not included in the scope of this review, there is an increasing evidence base supporting the use of hybrid models that combine elements of both centre‐based and home‐based cardiac rehabilitation delivery.

Further data are needed to determine: (1) whether the short‐term effects of home/digital‐telehealth and centre‐based cardiac rehabilitation models of delivery can be confirmed in the longer term; (2) the relative clinical effectiveness and safety of home‐based programmes for other heart patients, e.g. post‐valve surgery and atrial fibrillation.

Plain language summary

Home‐based versus supervised centre‐based cardiac rehabilitation

Review question

We compared home‐based cardiac rehabilitation programmes (including those that involve use of digital technology, such as websites and apps) with supervised centre‐based cardiac rehabilitation for adults with myocardial infarction (blood flow to the heart has stopped), angina (chest pain), heart failure (heart is unable to pump blood around the body properly) or who had undergone revascularisation (surgery to restore blood flow).

Background

Cardiac rehabilitation aims to restore people with heart disease to health, through a combination of exercise, education, and psychological support. Traditionally, centre‐based cardiac rehabilitation programmes (e.g. based at a hospital, gymnasium or in community/sport centre) are offered to people after cardiac events. Home‐based cardiac rehabilitation programmes, which can include digital platforms, have been introduced to increase access and participation.

Search date

We searched up to September 2022.

Study characteristics

We searched for randomised controlled trials (trials that randomly allocate participants to one of two or more treatment groups) looking at the effectiveness of home‐based (which may include digital/telehealth technology) versus supervised centre‐based cardiac rehabilitation programmes, in adults with heart disease.

We included 24 trials (3046 participants). We also found nine more studies and 14 trial registrations but they are ongoing or yet to be included in analyses. Most trials were relatively small (median 104 participants, range: 20 to 525). The average age of trial participants ranged from 51.6 to 69 years. Women accounted for only 19% of recruited participants; four trials did not include women. All trials included centre‐ and home‐based models of delivery that required supervision (either in person or remote) by healthcare professionals. Four trials used digital/telehealth technology to support their home‐based delivery.

Diagnoses recruited for the trials varied: nine studies included a mixed population with coronary heart disease, six studies in those who had experienced a heart attack/myocardial infarction, four studies following revascularisation, and five in those with heart failure.

Key results

We found that home‐ and centre‐based cardiac rehabilitation programmes are similar in benefits, measured in terms of numbers of deaths, exercise capacity and health‐related quality of life. Further data are needed to confirm if these short‐term effects of home/digital & telehealth‐ and centre‐based cardiac rehabilitation can be sustained over time.

Quality of the evidence

Evidence quality ranged from low (total mortality), to moderate (exercise capacity over 12 months and health‐related quality of life). The main reasons for the low assessment of quality was poor study reporting.

Background

Description of the condition

Cardiovascular diseases (CVDs), mainly coronary heart disease (CHD) and stroke, are the leading worldwide cause of mortality and are a major contributor to disability (Roth 2020). In 2019, an estimated 17.9 million people died from CVD, representing 32% of all global deaths (WHO 2021). Of these deaths, 85% were due to myocardial infarction (MI) and stroke (WHO 2021). Over three‐quarters of CVD deaths occurred in low‐ and middle‐income countries (WHO 2021).

CHD is caused by the build‐up of plaque inside the coronary arteries (atherosclerosis), causing arterial narrowing and reduced flow of oxygen‐rich blood to the heart. The main manifestations of CHD are angina pectoris (chest pain), myocardial infarction (MI), and heart failure. MI occurs when blood flow to the heart muscle is abruptly cut off as the result of a blockage in one or more of the coronary arteries, causing tissue damage. Over time, CHD can weaken the heart muscle and lead to arrhythmias or heart failure. CHD causes significant morbidity and mortality and, as a long‐term condition, it contributes greatly to disability in developed countries, accounting for 19% of total disability‐adjusted‐life‐years (DALYs) lost in European countries (European Cardiovascular Disease Statistics 2017). CHD can result in difficulties in functionality and performing everyday activities, and impairs sexual function (Racca 2010), all contributing to a reduction in health‐related quality of life (HRQoL) (Gravely‐Witte 2007).

In the United Kingdom (UK), an estimated 2.3 million people live with CHD – around 1.5 million men and 830,000 women (BHF 2021). Before the SARS‐CoV‐2 pandemic, ~100,000 people were admitted to hospital with MIs, and ~200,000 were diagnosed with heart failure annually in the UK (BHF 2021). With an ageing population, an increasing number of people are now living with CHD, including heart failure, and many individuals need support to manage their symptoms and improve their prognosis.(Dalal 2021).

People living with CVD are at significantly increased risk of severe outcomes (3.9 times higher) and death (2.7 times higher) from SARS‐CoV‐2 infection and COVID‐19 (BHF 2021).

Description of the intervention

Cardiac rehabilitation is a complex intervention that includes exercise training, physical activity promotion, health education, cardiovascular risk management and psychological support, personalised to the individual needs of patients with diagnosed heart disease (Richardson 2019). Historically, cardiac rehabilitation programmes were limited to exercise training (Taylor 2021). However, it is now routinely recommended that programmes also provide lifestyle education on CHD risk factor management plus counselling and psychological support, resulting in a more ‘comprehensive cardiac rehabilitation’ programme being offered to patients (Taylor 2021). A 2020 European position paper, in keeping with other national and international guidelines (Ambrosetti 2020), stated that "comprehensive cardiac rehabilitation has been recognised as the most cost‐effective intervention to ensure favourable outcomes across a wide spectrum of cardiovascular disease" (BACPR 2017; Pieopoli 2016).

Cardiac rehabilitation should be considered an essential part of the contemporary treatment of heart disease and is considered a priority in countries with a high prevalence of CHD (Taylor 2021). Cardiac rehabilitation has been shown to improve HRQoL and reduce future morbidity (Anderson 2016; Davies 2014; Taylor 2014). Based on evidence from previous meta‐analyses and systematic reviews, international guidelines give cardiac rehabilitation their highest recommendation (class I: evidence and/or general agreement that a given treatment or procedure is beneficial, useful and effective and should be recommended) based on an evidence rating of level A [data derived from multiple randomised controlled trials (RCTs) or meta‐analyses] or level B (data derived from a single RCT or large non‐randomised studies). More specifically, the evidence for cardiac rehabilitation is rated as follows for post‐acute coronary syndrome (ACS), post‐primary coronary angioplasty, and coronary artery surgery [patients with ACS (class 1, level A)] including ST‐segment elevation myocardial infarction, non‐ST‐segment elevation myocardial infarction, and unstable angina (class 1, level B). In addition, evidence for cardiac rehabilitation for patients undergoing reperfusion (e.g. coronary artery bypass graft, primary percutaneous coronary intervention, and percutaneous coronary intervention) is rated as class 1, level A by the American College of Cardiology/American Heart Association (Balady 2011; Kulik 2015; Smith 2011; Yancy 2013) and the European Society of Cardiology, (McMurray 2012; Roffi 2015; Steg 2012) and is recommended by the National Institute for Health and Care Excellence (NICE 2010; NICE 2013). Similar national and international recommendations based on a high level evidence are made for patients with newly diagnosed chronic heart failure and chronic heart failure with a step change in clinical presentation (class 1, level A) (McDonagh 2021).

Despite the evidence for clinical and cost‐effectiveness, participation in cardiac rehabilitation, traditionally delivered in hospital outpatient departments or community centres, has remained suboptimal, with overall participation rates < 20% in the US (Beatty 2018) and similar rates after a diagnosis of heart failure in Europe (Bjarnason‐Wehrens 2010). Poor participation has predominated in certain groups: women, older people, ethnic minorities, and those living in rural communities or who are socioeconomically deprived (Ritchey 2020). Consequently, calls were made for alternatives to centre‐based cardiac rehabilitation (Ambrosetti 2020; Arena 2012). Suggested interventions included rehabilitation at home facilitated by healthcare professionals and supported by telehealth technologies, to improve uptake (Clark 2015). The 2019 scientific statement by the American Heart Association and the American College of Cardiology in 2019 advocated for home‐based cardiac rehabilitation (Thomas 2019). Guidance from NICE on chronic heart failure in the UK in 2018 stated that “delivery of home‐based rehabilitation may increase access and uptake (NICE 2018). Telerehabilitation ("rehabilitation from a distance by using one or several devices monitoring and communicating patient specific information to the caregivers” (Frederix 2019)) which often involves telephones, videoconferencing, and mobile apps (telehealth) are increasingly being used as an adjunct to home‐based rehabilitation (Thomas 2019; Thomas 2020).

How the intervention might work

There are a number of mechanisms by which rehabilitation benefits patients, dependent on the cause of their heart disease. For people with CHD, approximately half of the 28% reduction in cardiac mortality achieved with exercise‐based cardiac rehabilitation has been attributed to reductions in major risk factors (e.g. reduction in lipids, blood pressure, and smoking) (Taylor 2006). For patients with ischaemic causes of heart failure, exercise training appears to improve myocardial perfusion by alleviating endothelial dysfunction, thereby dilating coronary vessels, and by stimulating new vessel formation by way of intermittent ischaemia (Piepoli 2004). Indeed, Haykowsky 2007 demonstrated that aerobic training in people with heart failure patients improves myocardial contractility and diastolic filling. In their meta‐analysis, Haykowsky 2007 demonstrated the benefits of exercise training in people with heart failure in terms of cardiac remodelling as measured by ejection fraction, end‐diastolic volume, and end‐systolic volume. Skeletal muscle dysfunction and wasting may also respond to exercise training (Haykowsky 2007). Regular physical activity by people with heart failure also stimulates vasodilation in the skeletal muscle vasculature and improves oxidative capacity (Hambrecht 1998). The inclusion of psycho‐educational interventions may improve patients' knowledge and risk factor behaviour (Brown 2013; Dickens 2013) and psychological well‐being, including levels of depression and anxiety.

Why it is important to do this review

Although the beneficial effects of cardiac rehabilitation have previously been demonstrated, participation remains suboptimal (Dalal 2012; Dalal 2021; Taylor 2021), particularly so in patients with heart failure (Dalal 2012; Dalal 2021; Taylor 2021). The number of patients with heart failure in the UK participating in rehabilitation decreased from 4969 (< 10% of eligible patients) before the pandemic (May 2019‐January 2020) to 1474 (< 5% of eligible patients) during the first wave of SARS‐CoV‐2 (February‐August 2020) (Ruano‐Ravina 2016). Analysis by the British Heart Foundation (BHF) published in 2020 mirrored other cardiac audits, showing a 30‐40% decrease in use of cardiology and rehabilitation services during the pandemic compared with a similar period in 2019 (Doherty 2020). SARS‐CoV‐2 has therefore led to further calls for alternatives to traditional centre‐based cardiac rehabilitation.

The suboptimal uptake of cardiac rehabilitation can be attributed to several factors, including barriers at the level of the clinician, patient, and health service (Dalal 2021; Taylor 2021). The absence of education on cardiac rehabilitation in the general medical and cardiology training of clinicians may contribute to the low rate of referral by physicians. For patients, several factors could influence their participation in a cardiac rehabilitation programme, such as the inconvenience (and costs of transport) of travelling to a centre‐ based programme held during the ‘9–5’ working day, especially for those in employment. At the health service level, barriers can include the capacity and funding of cardiac rehabilitation programmes and the availability of trained staff. For example, the 2019 UK National Audit of Cardiac Rehabilitation (NACR) showed that the majority (75.4%) of patients received group‐based, supervised cardiac rehabilitation compared with only 8.8% taking up home‐based cardiac rehabilitation (Doherty 2020). Barriers at these three levels are probably interactive. For example, travelling to centres and a dislike of group‐based rehabilitation sessions can be relevant for certain groups of patients, including women, ethnic minorities and people from areas of high deprivation who are elderly, living with multiple long‐term health conditions, or living in rural areas (Ruano‐Ravina 2016)

Over the last decades there has been an increasing amount of published evidence for home‐based models of cardiac rehabilitation, including those supporting by technology, hence the need to update this review. In the previous version of this Cochrane Review (Anderson 2017), the authors identified 23 head‐to‐head randomised controlled trials of home‐versus centre‐based cardiac rehabilitation. The authors reported the two methods of delivery to be equally effective for improving the clinical and health‐related quality of life outcomes in low risk patients after MI or revascularisation, or with heart failure. This, together with the absence of evidence of important differences in healthcare costs between the two approaches, led to the authors advocating for the expansion of home‐based cardiac rehabilitation programmes and suggesting that the choice of participating in a more traditional and supervised centre‐based programme or a home‐based programme should reflect the preference of the individual patient.

Objectives

To compare the effect of home‐based and supervised centre‐based cardiac rehabilitation on mortality and morbidity, exercise‐capacity, health‐related quality of life, and modifiable cardiac risk factors in patients with heart disease

Methods

Criteria for considering studies for this review

Types of studies

Randomised controlled trials (RCTs; individual or cluster level), including parallel‐group or cross‐over designs, were eligible for inclusion. We included studies reported as full text, those published as abstracts only, and unpublished data.

Types of participants

The study population included adults (≥ 18 years) who were post‐myocardial infarction (MI), had angina, or had undergone revascularisation (coronary artery bypass grafting (CABG), percutaneous transluminal coronary angioplasty or coronary artery stent) or who had heart failure, who had taken part, or been invited to take part, in cardiac rehabilitation. In trials with a mixed indication population, > 50% of the trial participants should have had a relevant diagnosis.

Studies were excluded if they included participants with heart transplants, those implanted with either cardiac resynchronisation therapy or implantable defibrillators, or those who had previously received cardiac rehabilitation.

Types of interventions

Home‐based cardiac rehabilitation is defined as a structured programme (that includes exercise training) with clear objectives for the participants, including monitoring, follow‐up visits, letters, telephone calls from staff or at least self‐monitoring diaries (Jolly 2006) and/or digital/telehealth interventions used (e.g. mobile/smartphone, mobile application [app], portable computer, Internet, biosensors (Rawstorn 2016)). The comparison group was centre‐based cardiac rehabilitation based in a variety of settings (e.g. hospital physiotherapy department, university gymnasium, community/sports centre). We included cardiac rehabilitation programmes whether they were based solely on exercise or included other intervention elements (comprehensive cardiac rehabilitation). We excluded trials that included 'hybrid' programmes, i.e. patients received a mix of centre‐based ± home‐based sessions.

Types of outcome measures

We sought to report the following primary and secondary outcomes, but they did not form the basis of our inclusion/exclusion criteria.

Primary outcomes
  • Total mortality.

  • Cardiac events:

    • Re‐infarction;

    • Total revascularisations (including CABG and percutaneous coronary intervention (PCI)); and

    • Cardiac associated hospitalisation.

  • Exercise capacity assessed by validated outcome measure (e.g. peak oxygen [VO₂] uptake, 6‐minute walk test).

  • Validated measures of HRQoL (e.g. Short Form Health Survey (SF‐36), Sickness Impact Profile, Nottingham Health Profile).

  • Withdrawal from the intervention programme (measured as number of completers).

Secondary outcomes
  • Modifiable coronary risk factors

    • blood lipid levels i.e. total, high density lipoprotein [HDL], and low density lipoprotein [LDL] cholesterol, and triglycerides,

    • systolic and diastolic blood pressure,

    • self‐reported smoking behaviour.

  • Adherence to cardiac rehabilitation (however reported).

  • Costs and health service use (e.g. staffing for cardiac rehabilitation delivery, use of medication, primary care contacts).

For event outcomes, we sought data on the number of trial participants who experienced the event at least once. Reporting one or more of the outcomes listed here in the trial was not an inclusion criterion for the review. Where a published report did not appear to report one of these outcomes, we accessed the trial protocol and contacted the trial authors to ascertain whether the outcomes were measured but not reported. Relevant trials which measured these outcomes but did not report the data at all, or not in a usable format, were included in the review as part of the narrative.

Search methods for identification of studies

Electronic searches

The search from the previously published Cochrane review (Taylor 2015) was updated by searching the following bibliographic databases on 16 September 2022:

  • CENTRAL Issue 8, 2022 in the Cochrane Library.

  • MEDLINE (Ovid, 1946 to 15 September 2022).

  • Embase (Ovid, 1980 to 2022 Week 36).

  • PsycINFO (Ovid, 1806 to September Week 1 2022).

  • CINAHL Plus (EBSCO, 1937 to 16 September 2022).

The search strategies were designed with reference to those of the previous version of this review (Taylor 2015). We searched the databases using a strategy combining selected MeSH terms and free‐text terms relating to patient education and coronary heart disease (CHD) and terms added for digital/telehealth, with filters applied to limit to RCTs. We used the Cochrane sensitivity‐maximising RCT filter for MEDLINE, and for Embase, and terms recommended in the Cochrane Handbook for Systematic Reviews of Interventions were applied (Lefebvre 2011). Adaptations of this filter were applied to CINAHL and PsycINFO. We translated the MEDLINE search strategy into the other databases using the appropriate controlled vocabulary, as applicable. We imposed no language or other limitations and gave consideration to variations in terms used and spellings of terms in different countries so that studies would not be missed by the search strategy because of such variations. See Appendix 1 for details of the search strategies used.

The reporting of search results was conducted in accordance with PRISMA (Moher 2009). Information about the number of studies identified, included and excluded, and the reasons for exclusion are summarised using a flow diagram (Figure 1).

*Two RCTs removed as follow‐up communication with trial lead investigators: neither trial was available/published to allow full assessment of their methods/risk of bias

**Attempts to seek further information were unsuccessful

Searching other resources

We handsearched reference lists of retrieved articles and systematic reviews for any studies not identified by the electronic searches. We also searched clinical trial registers on 16 September 2022; World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (http://www.who.int/ictrp/en) and ClinicalTrials.gov (https://clinicaltrials.gov) for ongoing clinical trials and sought expert advice. Attempts were made to contact all study authors where relevant information was not available in the published manuscript.

Data collection and analysis

Selection of studies

Two review authors (STJMc, SM, HD, or CC) independently screened titles and abstracts for inclusion of all the potentially relevant studies we identified as a result of the search and coded them as ‘retrieve’ or ‘do not retrieve.’ If there were any disagreements, a third author was asked to arbitrate (STJMc, SM, HD, CC, or RST). We identified and excluded duplicates and collated multiple reports of the same study so that each study rather than each report was the unit of interest in the review. We recorded the selection process in sufficient detail to complete a PRISMA flow diagram and Characteristics of excluded studies table (Liberati 2009). Where necessary, authors of included studies were contacted for missing information.

Data extraction and management

Two independent review authors (STJMc, SM, CC and HD) extracted study characteristics of included RCTs using a standardised data collection form which had been piloted on two RCTs included in the review. The following categories of data were extracted:

  • Methods: including study design, total duration of study, number of centres, setting, date of study conduct

  • Participants: including N randomised, N lost to follow‐up, N analysed, age, sex, CHD diagnosis, and inclusion and exclusion criteria

  • Intervention & control: including mode of exercise, duration, frequency and intensity, any co‐intervention and description of comparator

  • Outcome: primary and secondary outcomes

  • Funding, notable conflicts of interest of authors

Two independent review authors (RST, JA) extracted outcome data. If data were presented numerically (in tables or text) and graphically (in figures), the numeric data were used because of possible measurement error when estimating from graphs. Any discrepancies were resolved by arbitration. One review author (RST) transferred extracted data into Review Manager 5.3 (RevMan 2014), and checked data for accuracy against the data collection forms.

If there were multiple reports of the same study, we assessed the duplicate publications for additional data. We extracted outcome results at all follow‐up points post‐randomisation. We contacted study authors where necessary to provide additional information.

Assessment of risk of bias in included studies

The risk of bias in new trials was assessed by two reviewers independently (RST and JA) using the criteria outlined in Higgins 2011. We resolved any disagreements by discussion. We assessed the risk of bias according to the following domains:

  • random sequence generation

  • allocation concealment

  • blinding of participants and personnel

  • blinding of outcome assessment

  • incomplete outcome data

  • selective outcome reporting

In addition, evidence was sought that the groups were balanced at baseline and whether co‐interventions were delivered equally across the groups. We graded each potential source of bias as high, low or unclear and provided a quote from the study report together with a justification for our judgement in the Risk of bias tables that are appended to the Characteristics of included studies tables.

Measures of treatment effect

We extracted outcome results at follow‐up and the focus of this review was the between‐group difference in home‐based versus centre‐based groups. Primary outcomes relating to clinical event data were extracted as dichotomous outcomes for each study. Event data were expressed as risk ratios (RRs) with associated 95% confidence intervals (CI), and study sample sizes were based on the number randomised to treatment conditions. For continuous variables, mean differences (MDs) and 95% CIs were calculated for each outcome, with sample sizes based on the number completing assessments at each time point. When the results at follow‐up and differences between groups of the individual trials were not reported in the original publication, we calculated P values for the differences using the reported mean and standard deviation with the t‐test command in STATA (StataCorp 2021).

Given the variety of exercise capacity measures reported, results for this outcome were expressed as a standardised mean difference (SMD). We interpreted SMD as 0.2, 0.5,and 0.8 representing a 'small', 'medium', and 'large' effect size, respectively (Faraone 2008). Where a trial reported more than one exercise capacity endpoint, we used the first one reported in the publication. Other continuous outcomes were pooled as mean differences (MDs).

Unit of analysis issues

In accordance with the Cochrane Handbook for Systematic Reviews of Intervention (Higgins 2022), we ensured that the analysis was appropriate to the level at which randomisation occurred. All studies included in this review were simple parallel‐group RCTs with no cross‐over trials, and so there were no issues relating to unit of analysis. If we identify any cross‐over trials for future updates of this review, we will only include the first period of the study.

Three trials contained three arms: (1) Gordon 2002 compared two home‐based exercise groups (‘community’ & physician ‘supervised’) with a single home‐based programme; (2) Aamot 2014 compared two centre‐group (‘group’ & ‘treadmill’) programmes with a single home‐based programme; (3) Grace 2016 compared two centre‐based programmes (‘mixed’‐sex vs ‘women’ only) with a single home‐based programme. In all three cases, we divided the number randomised to the comparison group in half to obtain the denominator for data analysis; the mean and standard deviation for the comparator groups remained unchanged for both comparisons. One trial (Miller 1984) contained four arms with two home vs centre comparisons based on two different durations of intervention (11 & 26 weeks). Both trial subgroups ('brief' and 'expanded') are reported separately.

Dealing with missing data

We contacted study investigators to verify key study characteristics and obtain missing numerical outcome data where possible (e.g. when a study was available as abstract only or where only study designs/protocols were reported).

Where necessary, we used the RevMan calculator to calculate missing standard deviations using other data from the trial, such as confidence intervals, based on methods outlined in the Cochrane Handbook for Systematic Reviews of Interventions (Higgins 2022).

Assessment of heterogeneity

Heterogeneity amongst included studies was explored qualitatively (by comparing the characteristics of included studies) and quantitatively (using the Chi² test of homogeneity and I² statistic). Where appropriate, the results from included studies were combined for each outcome to give an overall estimate of treatment effect. An I2 statistic of ≥ 50% was taken to indicate substantive statistical heterogeneity. We undertook extensive meta‐regression to examine heterogeneity (see Subgroup analysis and investigation of heterogeneity).

Assessment of reporting biases

The funnel plot and the Egger test (Egger 1997) were used to examine small study bias for outcomes where there were 10 or more studies contributing data to the analysis (Higgins 2022).

Data synthesis

We performed meta‐analyses with 95% confidence intervals where appropriate (i.e. when treatments, participants, and the underlying clinical question were similar enough for pooling to make sense). Similar to our approach in previous review versions (Anderson 2017; Taylor 2015), a fixed‐effect meta‐analysis was used except where substantive statistical heterogeneity was indicated by an I² of ≥ 50%, in which case a random‐effects model was used. If a statistically significant difference was present using the random‐effects model, we also reported the fixed‐effect pooled estimate and 95% CI because of the tendency of smaller trials, which are more susceptible to publication bias, to be over‐weighted with a random‐effects analysis. Meta‐analyses were undertaken at two time points: (1) up to and including 12‐months and (2) > 12 months follow‐up. In both cases, we took the latest follow‐up, e.g. if a trial assessed outcomes at 3, 6, 12, 24, and 36 months, we used the outcome at 12 months for (1) and at 36 months for (2).

Subgroup analysis and investigation of heterogeneity

We undertook subgroup analysis using meta‐regression to examine potential treatment effect modifiers. We tested the following a priori hypotheses that there may be differences in the effect of home‐ and centre‐based cardiac rehabilitation programmes on total mortality, exercise capacity ≤ 12 months, withdrawal from the intervention programme (measured as no. completers), total cholesterol, and blood pressure, across the following subgroups:

  • case mix (CHD vs PCI vs HF);

  • type of cardiac rehabilitation (exercise‐only cardiac rehabilitation versus comprehensive cardiac rehabilitation);

  • 'dose' of exercise intervention (dose = number of weeks of exercise training x average number of sessions/week x average duration of session in minutes) (dose ≥ 1000 units versus dose < 1000 units);

  • follow‐up period;

  • year of publication;

  • sample size;

  • risk of bias (low risk in ≥ 4 items versus < 4 items); and

  • study location (Europe vs North America vs other).

For this update review and due to the increasing number of published trials using telerehabilitation, we included the subgroup of home + telerehabilitation vs home alone.

Given the relatively small ratio of trials to covariates, multivariable meta‐regression was not appropriate, and instead, limited to a univariate analysis; we only undertook meta‐regression when there were 10 or more trials contributing to the analysis (Higgins 2022).

Sensitivity analysis

If a statistically significant difference was present using the random‐effects model, we also reported the fixed‐effect pooled estimate and 95% CI because of the tendency of smaller trials, which are more susceptible to publication bias, to be over‐weighted with a random effects analysis.

Summary of findings and assessment of the certainty of the evidence

Two independent review authors (RST, JA) employed the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to interpret result findings and used GRADEpro GDT 2015 to import data from Review Manager to create a Summary of findings table. We created a Summary of findings table using the following outcomes:

  • total mortality;

  • exercise capacity;

  • withdrawal from the intervention programme (measured as no. of completers);

  • HRQoL.

We used the five GRADE considerations (study limitations, consistency of effect, imprecision, indirectness, and publication bias) to assess the certainty of a body of evidence as it related to the studies that contributed data to the meta‐analyses for the prespecified outcomes. We used methods and recommendations described in the Cochrane Handbook for Systematic Reviews of Interventions using GRADEpro software (Higgins 2022). We have justified all decisions to downgrade the certainty of evidence using footnotes, and have made comments to aid readers' understanding of the review, where necessary.

Results of the search

The previous 2017 version of this Cochrane Review contributed 21 trials to this latest update (Aamot 2014; Arthur 2002; Bell 1998; Carlson 2000; Cowie 2012; Dalal 2007; Daskapan 2005; Gordon 2002; Grace 2016; Jolly 2007; Karapolat 2009; Kassaian 2000; Kraal 2014; Marchionni 2003; Miller 1984; Moholdt 2012; Oerkild 2011; Piotrowicz 2010; Sparks 1993; Varnfield 2014; Wu 2006). Two RCTs that were included in the previous version have been excluded from this update as contact with the trialists indicated that these trials had not been published in full and therefore prevented RoB assessment (Hadadzadeh 2015; Haddadzadeh 2013).

For the updated search run in September 2022, a total of 14,457 records were identified through database searches and 13,891 records were screened following de‐duplication. We assessed a total of 319 full‐text records. From these, we included an additional three trials (Hwang 2017; Maddison 2019; Sagar 2012), resulting in a total of 24 included RCTs. A further nine publications were identified and are categorised as studies awaiting classification (see Characteristics of studies awaiting classification). Manual searching of trial registers also identified a further 14 ongoing studies. See Characteristics of ongoing studies.

Of the 24 studies included in this update, three studies had three arms and either compared a single home‐based programme with two supervised centre‐based exercise programmes (Aamot 2014 ‐ a supervised group or a treadmill exercise programme that were both centre‐based; Grace 2016 ‐ a supervised mixed‐sex or a supervised women‐only (single sex) supervised centre‐based programme) compared to a home‐based programme), or a centre‐based programme compared to two home based programmes (Gordon 2002 ‐ a physician‐supervised/nurse‐case‐managed home or a community‐based home programme compared to a centre‐based programme). One four‐arm trial compared two centre‐based and two home‐based programmes (Miller 1984 ‐ centre‐vs home programmes of either 11 or 26 weeks). This updated review therefore includes 28 home‐based versus centre‐based cardiac rehabilitation comparisons. We used the method for splitting sample size of shared comparator studies in accordance with the Cochrane Handbook for Systematic Reviews of Interventions (Higgins 2022). Marchionni 2003 reported outcomes for home‐based versus centre‐based care according to three patient age subgroups (i.e. 45 to 65, 66 to 75, > 75 years). Given the data reporting, we pooled these data to obtain single overall outcome results for home‐ and centre‐based groups.

The study selection process is summarised in the PRISMA flow diagram (Figure 1).

Included studies

Design

Two trials were formally designed using a non‐inferiority design (Hwang 2017; Maddison 2019).

Population

The 24 included trials recruited a total of 3046 participants. Most trials were relatively small in sample size (median 74 participants, range: 20 to 525). The average age of patients in the trials ranged from 51.6 to 69.0 years. Except for four trials (Kassaian 2000; Miller 1984; Sparks 1993; Wu 2006), all included women. However, women accounted for only ~20% of all participants who were recruited in the included studies. The mix of participants recruited to included trials varied, with nine studies including a mixed population of people with coronary heart disease (CHD) (Aamot 2014; Carlson 2000; Gordon 2002; Grace 2016; Jolly 2007; Kassaian 2000; Kraal 2014; Oerkild 2011; Piotrowicz 2010), six studies included patients post‐myocardial infarction (MI) (Bell 1998; Dalal 2007; Maddison 2019; Marchionni 2003; Miller 1984; Varnfield 2014), four recruited patients following revascularisation (Arthur 2002; Moholdt 2012; Sagar 2012; Wu 2006), and five studies included participants with heart failure (Cowie 2012; Daskapan 2005; Hwang 2017; Karapolat 2009; Piotrowicz 2010). A number of trials noted that patients were of low‐to‐moderate risk (i.e. they formally excluded high‐risk patients).

Settings & follow‐up

All trials used an individual patient level method for randomisation. Four studies were UK‐based (Bell 1998; Cowie 2012; Dalal 2007; Jolly 2007); four were based in the USA (Carlson 2000; Gordon 2002; Miller 1984; Sparks 1993); two studies each were from Australia (Hwang 2017; Varnfield 2014), Canada (Arthur 2002; Grace 2016); Norway (Aamot 2014; Moholdt 2012) and Turkey (Daskapan 2005; Karapolat 2009), and one each from China (Wu 2006), Denmark (Oerkild 2011), India (Sagar 2012), Iran (Kassaian 2000), Italy (Marchionni 2003), Netherlands (Kraal 2014), New Zealand (Maddison 2019), and Poland (Piotrowicz 2010). Most studies reported outcomes up to six months post‐randomisation. Only three studies reported longer‐term (> 12 months) follow‐up: 14 months (Marchionni 2003), 18 months (Arthur 2002) and 24 months (Jolly 2007).

Interventions

Fifteen studies compared comprehensive programmes (i.e. exercise plus education and/or psychological management) and the remainder reported only an exercise intervention (Aamot 2014; Daskapan 2005; Grace 2016; Karapolat 2009; Kassaian 2000; Kraal 2014; Miller 1984; Sagar 2012; Wu 2006). The cardiac rehabilitation programmes differed considerably in duration (range: 1 to 6 months), frequency (1 to 5 sessions per week) and session length (20 minutes to 60 minutes per session). Most programmes used individually tailored exercise prescription which makes it difficult to precisely quantify the amount of exercise undertaken. Centre‐based programmes typically provided supervised cycle and treadmill exercise, while virtually all home programmes were based on walking, with some level of intermittent nurse or exercise specialist telephone support.

Four trials formally used digital technology to provide a telerehabiliation home‐based delivery of cardiac rehabilitation. In the FIT@Home study (Kraal 2014) patients received individual coaching by telephone once a week, based on measured heart rate data that were shared through the Internet. In Varnfield 2014, a smartphone was used to deliver rehabilitation in patient's homes, and included health and exercise monitoring, motivational and educational material delivery, and weekly mentoring consultations. In Hwang 2017, a real‐time exercise and education intervention was delivered into the patients' home twice‐weekly, using online videoconferencing software. Similarly, the REMOTE‐CR study (Maddison 2019) provided individualised exercise prescription, real‐time exercise monitoring/coaching and theory‐based behavioural strategies via a bespoke telerehabilitation platform.

Details of included studies are listed in Characteristics of included studies.

Excluded studies

We excluded 291 studies from a full‐text review. The majority of these exclusions were systematic reviews (n = 95) or ineligible study designs (n = 47), or trials that did not meet the inclusion/exclusion criteria based on types of participants, interventions and comparators, or settings (N = 111). A number of studies were excluded on the grounds that they employed a hybrid model of rehabilitation i.e. a mixture of centre and home‐based delivery. Details of excluded studies are listed in the Characteristics of excluded studies.

Risk of bias in included studies

A summary of the risk of bias for each individual trial is shown in Figure 2 and an overall summary is provided in Figure 3.

Allocation

Although details of generation and concealment of random allocation sequence were often poorly reported, no studies were judged to be at high risk of bias.

Blinding

Given the nature of interventions being tested, it was not possible to blind participants or carers to group allocation. Thus, we did not formally assess the risk of performance bias from the non‐blinding of participants and/or personnel.

In such situations, blinding outcome assessors to knowledge of allocation is probably of greater importance (Moustgaard 2020). Three studies were judged to be at high risk of bias i.e. reported they did not undertake outcome blinding (Aamot 2014; Oerkild 2011; Varnfield 2014).

Incomplete outcome data

Loss to follow‐up varied considerably amongst studies and was often asymmetric across home‐ and centre‐based cardiac rehabilitation groups. Only a few trials examined the impact of losses to follow‐up or dropouts on outcome results. Four studies were judged as having a high risk of attrition bias with overall loss to follow‐up > 20% or marked asymmetrical loss to follow‐up across groups (Carlson 2000; Grace 2016; Kraal 2014; Varnfield 2014).

Selective reporting

We compared the reported outcomes in the results sections to the outcomes described in the published protocol or trial registration (where available) or as reported in the methods of the published papers. Most of the included studies fully reported on all the specified outcomes listed in their methods sections. No studies were judged to be at high risk of bias.

Groups balanced at baseline?

Given the relatively small size of included trials, there is a high risk of (chance) imbalance in baseline patient demographics, medical history and/or outcomes. However, we found generally good evidence of balance in baseline characteristics between groups and, in only two cases, there was objective evidence of imbalances in baseline characteristics (Arthur 2002; Cowie 2012).

Groups received the same co‐interventions?

When comparing two active modes of intervention delivery (i.e. home‐ vs centre‐based rehabilitation in this case), it is important to be able to judge whether the interventions were delivered similarly. However, because the rehabilitation intervention was usually tailored to the individual participant, it was difficult to quantify the precise level of intervention. Most trials were judged to be at low risk of bias, i.e. the home‐ and centre‐based programme groups appeared to be receiving comparable interventions (and co‐interventions). Four trials were considered to be at high risk of bias. Bell 1998, Carlson 2000 and Jolly 2007 included hospital cardiac rehabilitation programmes which were fixed in terms of frequency and content over the period of the study. In contrast, the home‐based intervention in these studies consisted of use of the Heart Manual 2016 where the participants could self‐regulate the frequency and nature of rehabilitation sessions they undertook. Kraal 2014 was also judged as having high risk of bias in this domain as, while telephone coaching was offered to the home‐based cohort in this study, no coaching was offered to patients receiving centre‐based cardiac rehabilitation.

Other potential sources of bias

Where reported, the source of funding was usually public (e.g. governmental or health research funder) and only one trial reported receiving commercial funding (Varnfield 2014) from a smartphone company.

Effects of interventions

See: Table 1

Primary outcomes

Total mortality

Twelve trials (14 comparisons) reported total mortality up to one year following the intervention (Aamot 2014; Bell 1998; Dalal 2007; Daskapan 2005; Haddadzadeh 2013; Jolly 2007; Kraal 2014; Miller 1984; Miller 1984 expanded; Moholdt 2012; Oerkild 2011; Piotrowicz 2010). A pooled analysis found no evidence of a significant difference in mortality at three to 12 months of follow‐up between home‐ and centre‐based cardiac rehabilitation (RR 1.19, 95% CI 0.65 to 2.16; participants = 1647; 12 studies ; I² = 0%; fixed‐effect; low‐certainty evidence; Analysis 1.1).

1.1. Analysis.

Comparison 1: Home‐base vs. centre‐based cardiac rehabilitation (CR), Outcome 1: Total mortality

Jolly 2007 reported that there was no between‐group difference in mortality at 24 months follow‐up (home group: 6/263; centre group: 3/262, P = 0.32).

Subgroup analyses

Predictors of treatment effect on total mortality were examined across the longest follow‐up period of each individual study, using univariate meta‐regression. We found no evidence that mortality risk was associated with case mix, type of cardiac rehabilitation, duration of follow‐up, year of publication, study location, study location (continent) or sample size (Table 2).

Cardiac events

Only six studies (Arthur 2002; Dalal 2007; Jolly 2007; Maddison 2019; Oerkild 2011; Piotrowicz 2010) reported cardiac events, including re‐infarction, revascularisation (coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI)) or cardiac‐associated hospitalisation. Given the differing nature of the events reported, it was not possible to pool the data.

Dalal 2007 and Jolly 2007 reported no difference in revascularisation or recurrent myocardial infarction (MI) events between home‐ and centre‐based cardiac rehabilitation. Piotrowicz 2010 reported no heart failure‐related admissions in either group. Oerkild 2011 stated that “the number and length of acute and non‐acute admissions and adverse events (admission for MI, progressive angina, decompensated congestive heart failure, severe bleeding, new malignant disease and performance of (percutaneous coronary intervention)) to be equally distributed (across groups at 12 months follow‐up)” but did not report numbers of events. The six‐year follow‐up report of the Arthur 2002 study described that a total of 46/79 (62%) centre‐based cardiac rehabilitation patients experienced a hospitalisation compared to 35/70 (50%) in the home‐based group (P = 0.31). However, the total number of hospitalisations in centre‐based patients was greater than that in home‐based participants (79 versus 42, P < 0.0001). Maddison 2019 reported that four (of 86) patients in the home‐based arm experienced a hospitalisation at 24 weeks compared to one patient (of 80) in the centre‐based group.

Subgroup analyses

Due to the small number of studies reporting cardiac events, it was not possible to examine the effects of potential treatment effect modifiers on these outcomes.

Small study bias

Due to the small number of studies reporting cardiac events, it was not possible to examine small study bias.

Exercise capacity

All included studies reported on exercise or functional capacity in the short‐term (8 weeks to 12 months follow‐up); three (Arthur 2002; Jolly 2007; Marchionni 2003) presented longer‐term data (> 12 months follow‐up) and one reported outcomes at six‐year follow‐up (Arthur 2002). All studies reported absolute exercise capacity at follow‐up, except two trials (3 comparisons; Gordon 2002 supervised; Gordon 2002 not supervised; Oerkild 2011) which reported change in exercise capacity at follow‐up compared to baseline. Studies reported exercise capacity using a variety of metrics that included direct measures of oxygen uptake, walking distance, and workload on a static cycle.

The pooled analysis showed no evidence of a difference in short‐term exercise capacity between home‐based and centre‐based cardiac rehabilitation (SMD ‐0.10, 95% CI ‐0.24 to 0.04; participants = 2343; studies = 24 (28 comparisons); I² = 60%; random‐effects; low‐certainty evidence; Analysis 1.2).

In a pooled analysis of three studies reporting longer‐term data (> 12 months; Arthur 2002; Jolly 2007; Marchionni 2003), there was no evidence of a difference in exercise capacity following home‐based cardiac rehabilitation compared with centre‐based cardiac rehabilitation (SMD 0.11, 95% CI ‐0.01 to 0.23; participants = 1074; studies = 3; I² = 0%; fixed‐effect; moderate‐certainty evidence; Analysis 1.3).

Comparison 1: Home‐base vs. centre‐based cardiac rehabilitation (CR), Outcome 3: Exercise capacity 12 to 24 months

Arthur 2002 reported that mean peak oxygen consumption (VO₂) at six‐year follow‐up was higher in the 96 participants who had undergone home‐based cardiac rehabilitation (1543 mL/min (SD 444)) compared to the 74 participants who had received centre‐based cardiac rehabilitation (1412 mL/min (SD 356); P = 0.01).

Subgroup analyses

We found no evidence that exercise capacity is associated with case mix, dose of exercise, type of cardiac rehabilitation, duration of follow‐up, year of publication, study location, study location (continent) or sample size (Table 3).

Health‐related quality of life (HRQoL)

Eighteen trials reported validated measures of HRQoL (Table 4). These included generic HRQoL instruments (e.g. EQ‐5D (EuroQoL 1990), Nottingham Health Profile (Hunt 1980), Short‐Form 36 (SF‐36; McHorney 1993), Sickness Impact Profile (Bergner 1976) as well as disease‐specific instruments (e.g. MacNew; Höfer 2004; Minnesota Living With Heart Failure Questionnaire, MLWHF; Rector 1993). Given the variation in HRQoL outcomes reported (including total and domain scores of both generic and disease‐specific tools), as per our approach in the previous review versions (Anderson 2017; Taylor 2015), pooling across studies was deemed inappropriate.

We adopted a vote‐counting approach to summarise the data and direction of effect. Whilst this synthesis without meta‐analysis (SWiM) method has significant limitations, we believe it to be the only method that allows us to communicate the results in a transparent and concise format (Campbell 2020). Whilst individual studies reported consistent improvements in HRQoL at follow‐up with both home‐ and centre‐based cardiac rehabilitation compared to baseline, most of the evidence (N = 71 / 77 comparisons of either total or domain scores) showed no significant difference in HRQoL at follow‐up between centre and home.

Withdrawals from the intervention programme

Using the number of 'completers', i.e. the number of participants with outcome data at follow‐up, we found no difference in the level of study completion with home‐based compared with centre‐based trials (RR 1.03, 95% CI 0.99 to 1.08; participants = 2638; studies = 23 (26 comparisons); I² = 55%; random‐effects; low‐certainty evidence; Analysis 1.4).

We found no evidence that withdrawal from the intervention programme (measured as no. completers) risk was associated with case mix, dose of exercise, type of cardiac rehabilitation, duration of follow‐up, year of publication, study location, study location (continent), or sample size (Table 5).

Blood lipids

Nine of the included trials (10 comparisons) reported data on blood lipids (Bell 1998; Carlson 2000; Dalal 2007; Gordon 2002; Jolly 2007; Kassaian 2000; Maddison 2019; Moholdt 2012; Oerkild 2011; Varnfield 2014). Study results were expressed as millimols per litre (mmol/L; Bell 1998; Dalal 2007; Jolly 2007; Maddison 2019) or milligrams per decilitre (mg/dL; Carlson 2000; Gordon 2002; Kassaian 2000); in the latter case we converted values into mmol/L before pooling for meta‐analysis.

Total cholesterol

Pooled analysis revealed no evidence of a difference in the total cholesterol between home‐ and centre‐based groups (MD 0.06 mmol/L, 95% CI ‐0.09 to 0.21; participants = 1290; studies = 10, comparisons = 11; I² = 52%; random‐effects; Analysis 1.5).

Comparison 1: Home‐base vs. centre‐based cardiac rehabilitation (CR), Outcome 5: Total cholesterol 3 to 12 months (mmol/L)

Jolly 2007 reported no significant difference between home‐ and centre‐based cardiac rehabilitation groups in total cholesterol concentration at 24 months follow‐up (MD = ‐0.11 mmol/L, 95% CI 0.06 to ‐0.28).

Subgroup analyses

There was weak evidence (P < 0.05) that the impact of cardiac rehabilitation was associated with both type of programme (larger effect with exercise only vs comprehensive rehab trials) and study location (larger effects in trials from North America and other countries than from Europe). There was no association with other trial covariates i.e. case mix, dose of exercise, duration of follow‐up, year of publication, study location, or sample size (Table 6).

Subgroup analyses

Due to the small number of studies reporting HDL cholesterol, it was not possible to examine the effects of potential treatment effect modifiers on these outcomes.

Small study bias

Due to the small number of studies reporting HDL cholesterol, it was not possible to examine small study bias in these outcomes.

Low‐density lipoprotein (LDL) cholesterol

Blood pressure

Eleven included trials (13 comparisons) reported on systolic and diastolic blood pressure respectively (Aamot 2014; Carlson 2000; Dalal 2007; Daskapan 2005; Gordon 2002; Gordon 2002 Supervised; Jolly 2007; Kassaian 2000; Maddison 2019, Oerkild 2011, Varnfield 2014) or systolic blood pressure alone (Bell 1998).

No evidence of a difference was found at follow‐up between groups in either pooled systolic blood pressure (MD 1.17 mmHg, 95% CI ‐0.44 to 2.77; participants = 1455; studies = 12, comparisons = 14; I² = 48%; fixed‐effects; Analysis 1.9) or diastolic blood pressure (MD 0.80 mmHg, 95% CI ‐0.76 to 2.35; participants = 1309; studies = 11, comparisons = 13; I² = 52%; random‐effects; Analysis 1.10) following home‐ or centre‐based cardiac rehabilitation.

At 24 months follow‐up, Jolly 2007 reported no significant difference between home‐ and centre‐based cardiac rehabilitation groups in systolic blood pressure (MD = ‐0.85 mmHg; 95% CI 2.48 to ‐4.18) or diastolic blood pressure (MD ‐0.76 mmHg, 95% CI 1.12 to ‐2.64).

Subgroup analyses

No statistically significant associations were seen in any of the analyses for systolic or diastolic blood pressure with case mix, dose of exercise, type of cardiac rehabilitation, duration of follow‐up, year of publication, study location, study location (continent), or sample size (Table 7, Table 8).

Small study bias

There was some evidence of funnel plot asymmetry for systolic blood pressure (Egger test P = 0.025; Figure 1) but not for diastolic blood pressure (Egger test P = 0.102; Figure 8).

Smoking behaviour

Five studies (6 comparisons) reported on participants' self‐reported smoking behaviour at three to 12 months of follow‐up (Bell 1998; Dalal 2007; Gordon 2002; Gordon 2002 Supervised; Jolly 2007; Oerkild 2011). There was no evidence indicating a difference in the proportion of smokers at follow‐up between home‐ and centre‐based cardiac rehabilitation (RR: 1.02, 95% CI 0.83 to 1.27; participants = 986; studies = 5, comparisons = 6; I² = 0%; fixed‐effect; Analysis 1.11).

Comparison 1: Home‐base vs. centre‐based cardiac rehabilitation (CR), Outcome 11: Smoking 3 to 12 months

Jolly 2007 reported no difference in smoking between home‐ and centre‐based arms at 24 months (RR: 1.16, 95% CI 0.58 to 33.3). There was evidence of a consistent reduction in self‐reported smoking behaviour following both home‐ and centre‐based cardiac rehabilitation. This finding was confirmed in the one study that used cotinine‐validated assessments of smoking (Jolly 2007).

Subgroup analyses

Due to the small number of studies reporting smoking, it was not possible to examine the effects of potential treatment effect modifiers on these outcomes.

Small study bias

Due to the small number of studies reporting smoking behaviour, it was not possible to examine small study bias.

Adherence

Eighteen studies reported data on adherence to cardiac rehabilitation over the duration of the study (Table 9) with most (13) only reporting session attendance or completion which can only be considered a proxy measure of exercise adherence. Some studies reported more than one measure of adherence. Pooling across studies was therefore deemed to be inappropriate. Nine studies (Carlson 2000; Cowie 2012; Dalal 2007; Gordon 2002; Grace 2016; Jolly 2007; Karapolat 2009; Maddison 2019; Miller 1984) found no evidence of a significant difference in the level of adherence between groups. Superior adherence to home‐based cardiac rehabilitation was reported in six studies (Arthur 2002; Hwang 2017; Kraal 2014; Marchionni 2003; Piotrowicz 2010; Varnfield 2014) and evidence of superior adherence in centre‐based cardiac rehabilitation in one study (Aamot 2014). Three other studies reported adherence (Daskapan 2005; Moholdt 2012; Sparks 1993) but it was not possible to assess if there was a statistically significant difference between home‐ and centre‐based cardiac rehabilitation.

Costs and health service use

Eight studies reported costs (Table 10). Differences in currencies and timing of studies meant that it was not possible to compare the costs directly across studies. In six of these studies, healthcare costs associated with cardiac rehabilitation were lower for the home‐based than centre‐based programmes (Carlson 2000; Dalal 2007; Hwang 2017; Maddison 2019Marchionni 2003; Varnfield 2014), although cost was significantly lower in only one study (Dalal 2007). Jolly 2007 found that home‐based cardiac rehabilitation was more expensive than centre‐based cardiac rehabilitation, although the costs of the two would have been the same if participant costs were included. One study (Cowie 2012) included the costs of a no‐cardiac rehabilitation control and showed that cardiac rehabilitation costs were offset by a reduction in hospital admissions over five years, resulting in a substantive cost‐saving when compared with control, i.e. GBP ‐3304 per participant for home‐based cardiac rehabilitation and GBP ‐3784 per participant for hospital‐based cardiac rehabilitation.

Discussion

Summary of main results

The traditional mainstay approach to cardiac rehabilitation delivery in many countries is a face‐to‐face inpatient and outpatient provision, which takes place in a hospital or community facility setting. In spite of the evidence of benefits of cardiac rehabilitation in CHD, PCI, and heart failure populations (Anderson 2016; Long 2019) and associated strong clinical guideline recommendations (Ponikowski 2016; Smith 2011), the utilisation of cardiac rehabilitation remains stubbornly poor across the globe. Whilst the barriers to cardiac rehabilitation access are complex (Dalal 2021; Taylor 2021), the availability of home‐based programmes, including digital/telehealth technology, provides an opportunity to increase uptake and participation in cardiac rehabilitation. The SARS‐CoV‐2 pandemic has had a dramatic negative impact on cardiac rehabilitation access (Scherrenberg 2020). This can be illustrated by the UK National Audit, which has observed more than a two‐third decrease in cardiac rehabilitation attendance in patients with heart failure from the pre‐SARS‐CoV‐2 period (4969 patients, May 2019 to Jan 2020) to post‐SARS‐CoV‐2 (1474 patients, Feb 2020 to Aug 2020) (Doherty 2020). However, this drop in uptake was associated with a substantial increase in the proportion of patients enroling in home‐based CR programmes, increasing from 22.2% to 72.4% in the same respective time frames.

This updated review included 24 trials which randomised 3046 participants following an MI or PCI or with heart failure, to either home‐based or centre‐based cardiac rehabilitation. Although models of home‐based rehabilitation varied widely, all studies included formal supervision by a qualified healthcare or exercise professional. Three of the included trials were based on the Heart Manual model (Bell 1998; Dalal 2007; Heart Manual 2016; Jolly 2007), a programme that consists of a self‐help manual supported by a nurse facilitator (Lewin 1992). Four trials used digital technology to support home‐based delivery of cardiac rehabilitation (Hwang 2017; Kraal 2014; Maddison 2019; Varnfield 2014), including real‐time exercise monitoring/coaching and theory‐based behavioural strategies via a bespoke digital/telehealth platform.

Across this evidence base, we found no evidence supporting important differences in outcomes for patients receiving home‐based or centre‐based cardiac rehabilitation either in the short‐term (3 to 12 months) or longer‐term (up to 24 months) for mortality, cardiac events, exercise capacity, modifiable risk factors (total cholesterol; LDL cholesterol; systolic blood pressure; diastolic blood pressure; proportion of smokers at follow‐up) or HRQoL or trial completion. There was a small outcome difference in favour of centre‐based participants for HDL cholesterol. In contrast, in home‐based participants, there was some evidence of higher levels of programme adherence attributed to attendance. We found no consistent evidence to support an important difference in the average cost per patient of providing home‐based versus centre‐based programmes.

Overall completeness and applicability of evidence

The inclusion criteria for this review are broad, in order to reflect current practice where an increasingly diverse patient population is accessing cardiac rehabilitation services (BACPR 2017). While the original version of this review was limited to trials in participants with stable CHD either following an acute MI or PCI (Taylor 2010), updates of this review have included an increasing number of trials in people with heart failure (Taylor 2015). However, because of the inclusion of home‐based programmes, the majority of trials have traditionally focused on low‐risk patients. Moreover, only ~20% of all participants included in this review were women and the majority of trials took place in high‐income settings.

Interventions, especially home‐based programmes, varied substantially in their content, dose, and level of healthcare staff support/supervision. Few studies reported fidelity (whether the intervention was delivered as intended) and details of the actual level of intervention implemented, both key aspects in understanding of the impact and replication of a complex intervention, such as cardiac rehabilitation (Hoffmann 2014). As details of interventions were often poorly reported, it was difficult to assess whether the cardiac rehabilitation programmes would meet current recommendations of good practice (Ambrosetti 2020; BACPR 2017).

Quality of the evidence

Methods of randomisation (sequence generation and concealment) and outcome blinding were generally poorly reported across the included trials, although there was some evidence of an improvement in the certainty of reporting in more recent trials. Due to this poor reporting, the certainty of the evidence for outcomes was assessed as 'moderate' at best. Other reasons for downgrading the certainty of evidence included inconsistency (exercise capacity ≤ 12 months and withdrawal from the intervention programme (measured as number of completers)) and imprecision (mortality).

Potential biases in the review process

This study sought to bring together a comprehensive and contemporary synthesis of the RCT evidence directly comparing home‐ (with or without a digital/telehealth platform) versus centre‐based cardiac rehabilitation. However, we recognise that our review has some potential biases.

Firstly, given the inconsistent reporting of outcomes, we were unable to judge the degree of publication bias for all outcomes, although there was no evidence of funnel plot asymmetry or statistically significant Egger tests for the majority of outcomes where this was tested (total mortality, exercise capacity, total cholesterol or diastolic blood pressure).

Second, the variation and complexity in HRQoL reporting (including total and domain scores of both generic and disease‐specific tools) meant that, as seen in previous review versions (Anderson 2017; Taylor 2015), we were not able to quantitatively pool outcomes using standardised meta‐analytic approaches and, instead, we used a synthesis without meta‐analysis (SWiM) approach (Campbell 2000).

Third, there was evidence of considerable statistical heterogeneity across a number of outcomes. This is likely to reflect the substantial clinical heterogeneity across trials both in terms of their patient populations and the range of home‐ and centre‐based cardiac rehabilitation interventions. Most studies were of relatively short duration, with only three trials reporting outcomes beyond 12 months of follow‐up (Arthur 2002; Jolly 2007; Marchionni 2003). The number of deaths and cardiac events reported by most trials was therefore correspondingly small.

Finally, it has been hypothesised that patient preference may have an impact on uptake and adherence to home‐based cardiac rehabilitation (Grace 2005). However, such a hypothesis is difficult to test in a traditional parallel two‐group RCT design and, therefore, our finding of similar adherence between home‐ and centre‐based cardiac rehabilitation needs to be interpreted with caution, especially as measuring adherence accurately remains problematic and is variable across studies (Bollen 2014; Newman‐Beinart 2017). One included trial (Dalal 2007) employed a comprehensive cohort design in addition to the randomised element of home‐ and centre‐based allocation in which there was also a patient preference element (participants could choose between home‐ and hospital‐based cardiac rehabilitation). The study authors reported that outcome differences between the home and hospital arms in the preference (non‐randomised) sample were very similar to those in the randomised comparison. Adherence to home‐based cardiac rehabilitation was also comparable between the randomised (75%) and preference arms (73%). This finding does not support the hypothesis that patients who can choose a programme to suit their lifestyle and preferences will have a higher adherence rate and improved outcomes. However, as with the randomised comparison, the number of participants in the preference arms was small (N = 126).

Agreements and disagreements with other studies or reviews

Whilst the findings of this update that the outcomes and costs of home‐ versus centre‐based cardiac rehabilitation are similar is consistent with the previous versions of this Cochrane Review (Taylor 2010; Taylor 2015; Buckingham 2016), this update does provide additional evidence that includes: heart failure patients, collection/reporting of additional HRQoL data, and trials of home‐based programmes that include a digital/telehealth technology framework. We did not include trials of centre‐based programmes including digital/telehealth technology.

A number of recent systematic reviews assessed the impact of home and digital/telehealth‐rehabilitation programmes against usual care or centre‐based rehabilitation. One meta‐analysis concluded that the gains in exercise capacity and HRQoL with digital/telehealth rehabilitation in CHD patients appeared to be comparable with those seen with centre‐based delivery (Ramachandran 2021). Another review reported that home‐based cardiac rehabilitation programmes are as effective as centre‐based programmes in terms of mortality, morbidity, short‐term exercise capacity, blood pressure, smoking cessation, and HRQoL (Crawford‐Faucher 2010). A recent systematic review assessed the safety of home‐based cardiac rehabilitation programmes and concluded that the risk of adverse events occurring is low and therefore cardiac patients should be encouraged to undertake physical exercise regularly in their own environment if not attending centre‐based sessions and be reassured that it is safe to do so.

Several cardiac rehabilitation programmes are now using this hybrid approach to deliver cardiac rehabilitation (Imran 2019) which typically involves patients initially undergoing centre‐based cardiac rehabilitation and then evolution to longer‐term maintenance through technology‐supported, home‐based sessions. Given that such hybrid programmes do not meet the inclusion criteria of this review, we have not included the evidence here for such a model of delivery.

Authors' conclusions

Implications for practice.

Supervised home/digital‐telehealth and centre‐based models of cardiac rehabilitation appear to be of similar effectiveness in improving clinical outcomes and HRQoL in post‐MI, PCI, and heart failure patients and they present a low risk of adverse events. This finding, together with a similar average cost per patient between the approaches, supports both the wider implementation of alternative models to centre‐based programmes in order to improve access and uptake of cardiac rehabilitation, especially in the midst of the SARS‐CoV‐2 pandemic. Where healthcare settings have sufficient resources, the offer of centre‐ or home/digital‐based programmes should consider the preference of the individual patient. Hybrid models combining both centre‐and home‐based cardiac rehabilitation delivery modalities are gaining popularity and a developing evidence base but not reviewed here (Wu 2018).

Implications for research.

Further data are needed to confirm whether the short‐term benefits of home/digital‐telehealth‐ and centre‐based modes of delivery of cardiac rehabilitation continue into the longer term. Evidence is also needed of the use of supervised centre‐ and home/digital‐telehealth rehabilitation models in other cardiac populations, such as stable angina pectoris, atrial fibrillation, congenital heart disease, and post‐valve surgery. Where future trials directly compare different models of cardiac rehabilitation, they need to consider adequately powered non‐inferiority/equivalence study designs. To inform practice and policy, future studies also need to include consideration of costs, better report intervention fidelity and adherence, and more consistently report validated patient‐relevant outcomes.

Study characteristics
Methods Study design: Multi‐centre RCT with 3 parallel groups: centre‐based group exercise, centre‐based treadmill exercise, or home‐based exercise
Number of centres: 2
Country: Norway
Dates patients recruited: October 2009 to April 2011
When randomised: After the baseline tests
Maximum follow‐up: 12 weeks
Participants Inclusion criteria: Aged over 18 years, diagnosed MI, CABG surgery, or acute coronary syndrome (ACS), and able to perform a maximal treadmill test
Exclusion criteria: Heart failure, severe arrhythmias, drug abuse, or a medical condition contraindicative to high‐intensity training
N randomised: total: 90; home‐based cardiac rehabilitation: 28; centre‐based cardiac rehabilitation (treadmill exercise): 34; centre‐based cardiac rehabilitation (group exercise): 28
Method of assessment: NR
Diagnosis (% of pts):
Previous AMI: home‐based cardiac rehabilitation: 71.4%; treadmill exercise: 67.6%; group exercise: 64.3%
Previous CABG: home‐based cardiac rehabilitation: 21.4%; treadmill exercise: 26.5%; group exercise: 25.0%
ACS: home‐based cardiac rehabilitation: 7.2%; treadmill exercise: 5.9%; group exercise: 10.7%
Age (mean ± SD): total: NR; home‐based cardiac rehabilitation: 58 ± 8 years; treadmill exercise: 56 ± 9 years; group exercise: 58 ± 8 years
Percentage male: total: 88.9%; home‐based cardiac rehabilitation: 96.4%; treadmill exercise: 82.4%; group exercise: 89.3%
Ethnicity: NR
Interventions All participants in all groups performed HIT twice a week for 12 weeks.
Every session started with a 10‐minute warm‐up at low‐to‐moderate intensity (50% to 70% of peak heart rate, HR) and continued with four intervals lasting 4 minutes each, at an exercise intensity of 85% to 95% of peak HR. Each interval was separated by 4 minutes of active breaks at an intensity of 70% of peak HR. After the last interval, a cool‐down period of 3 to 5 minutes was performed at 50% of peak HR. All participants were individually instructed in use of the HR monitor, and how to reach target HR. As aerobic capacity increased, the participants increased work load to maintain relative exercise intensity. Completion of 70% of the exercise sessions was considered to be training per‐protocol.
Home‐based:
The home‐based exercise started with two initial sessions with personal instruction of a physiotherapist where they learned how to perform HIT and to use the HR monitors. These sessions were performed as up‐hill walking or jogging. After the introduction, HIT was performed in preferred exercise mode in their home environment; up‐hill walking, cross‐country skiing, bicycling, running, or using indoor equipment such as treadmills or cross‐trainers. All participants varied their exercise mode, but they kept to the exercise design and relative exercise intensity. A Holter electrocardiogram was recorded during the first exercise session to ensure that no arrhythmia occurred during or immediately after exercise.
Time of start after event: NR
Components: Exercise only

All outcomes High risk "...significantly more [centre‐based CR] participants dropped out", "Because more [centre‐based CR] participants dropped out and failed to return for their 6‐month [exercise test] evaluation, this evaluation is a representation of more compliant patients”.
Selective reporting (reporting bias) Low risk All outcomes described in the methods section were reported in the results.
Groups balanced at baseline? Low risk “…only significant difference between groups was a higher resting systolic blood pressure in [centre‐based CR] …selected demographic and psychological measures including socioeconomic status and social support were comparable between the 2 groups at baseline”.
Groups received same co‐intervention(s)? High risk “The primary differences in the [home‐based CR] compared with the [centre‐based CR] included: …(2) an ongoing weekly education/support group, and (3) education and counselling that emphasized overcoming barriers associated with developing independent exercise and nutrition behaviours”.
Although both groups received exercise training, education, and counselling, the amount and nature of this intervention were different between groups.

Risk of bias
Bias Authors' judgement Support for judgement
Random sequence generation (selection bias) Low risk "Patients who consented to randomisation were randomised on an individual basis with minimisation by (1) original diagnosis (MI/revascularisation), (2) age (< 50/50‐74/75+ years), (3) sex, (4) ethnicity (Caucasian/Asian/other) and (5) hospital of recruitment."
Allocation concealment (selection bias) Low risk "Allocation was undertaken by the Birmingham Cancer Clinical Trials Unit, a group that was independent from the trial team …When a patient agreed to be randomised…the research nurse telephoned the Clinical Trials Unit…and was given an allocation group."
Blinding of outcome assessment (detection bias)
All outcomes Low risk "Assessments were blinded, with follow‐up undertaken by a research nurse who had neither recruited the patient nor provided home cardiac rehabilitation support."
Incomplete outcome data (attrition bias)
All outcomes Low risk “A sensitivity analysis was undertaken on the 12‐month data to assess the potential impact of the missing values for the ISWT, [systolic] BP, [diastolic] BP, [total cholesterol] and the Hospital Anxiety and Depression Scale scores.”
Selective reporting (reporting bias) Low risk All outcomes described in the methods section were reported in the results.
Groups balanced at baseline? Low risk “Demographic characteristics, diagnosis, past medical history and cardiac risk factors were well matched between the two arms at baseline.”
Groups received same co‐intervention(s)? High risk Although both groups received exercise, education and stress management, the nature and amount of intervention between groups were different.

Interventions Description of home‐based cardiac rehabilitation: Patients in the HT group received three initial supervised training sessions. During these sessions, patients received instructions on how to use a wearable heart rate monitor (Garmin Forerunner 70) and how to upload the recorded exercise data to a web application (Garmin Connect) through the Internet. The web application was used to review the training data by the patient, the physical therapist and the exercise specialist. During the first sessions, the patients were also familiarised with the training programme (duration, intensity) and their preferred training modality in the home environment was discussed. After three supervised training sessions, patients in the HT group started training in their home environment.
Time of start after event: NR
Components: Exercise plus behavioural change
Aerobic exercise:
Modality: Patient’s preferred training modality

Length of session: 45 to 60 min
Frequency/no of sessions: at least two training sessions per week
Intensity: 70% to 85% of maximal heart rate
Resistance training included? No
Total duration: 12 weeks
Intermittent nurse or exercise specialist telephone support? Patients received feedback on training frequency, duration and intensity from the physical therapist once a week via telephone. After 12 weeks, the telephonic feedback was terminated and the patients were advised to continue their training with the heart rate monitor.
Co‐interventions: Patients in the home‐based training group received coaching from their therapist through weekly telephone calls. During this phone call the therapist gave feedback on training parameters that were measured during the preceding week, and discussed progress with respect to the personal training goals. In addition, based on the principles of motivational interviewing, they discussed barriers and facilitative factors in adhering to the exercise training protocol.

Other: “The REMOTE‐CR platform comprised a smartphone and chest‐worn wearable sensor (BioHarness 3, Zephyr Technology, USA).
App features enabled real‐time remote exercise monitoring and coaching, retrospective exercise performance review, goal‐setting, behaviour change education and social support.
Behavioural intervention content was grounded in self‐efficacy and self‐determination theories, and the Taxonomy of Behaviour Change Techniques.
During exercise training, participants’ physiological (heart and respiratory rate, single lead ECG) and geopositional data were displayed in the smartphone app for self‐monitoring, streamed to a web server via 3G/4G/Wi‐Fi, and visualised in the web app for exCR specialist review.
ExCR specialists provided real‐time individualised audio coaching, feedback and social support throughout (but not prior to) real‐time exercise monitoring. Participants received audio communications via earphones to optimise usability and preserve the real‐time context of message content. Finally, participants received behaviour change education via direct messaging.

Ethnicity: NR
Interventions Description of home‐based cardiac rehabilitation: To make the ET safe for HF patients, the following recommendations were taken into account: (i) special attention was paid to appropriate patient risk stratification before cardiac rehabilitation; (ii) contraindications to ET were never overlooked; (iii) in patients with an implantable cardioverter defibrillator (ICD), maximal training HR was set at 20 bpm lower than the defibrillator discharge threshold; and (iv) in patients with a pacemaker, the rate‐response function was switched on, enabling HR adjustment to the physical effort which facilitates reaching the desired training HR. Exercise training was planned individually for each patient during hospitalisation. The chosen workload reflected individual effort tolerance with regard to: (i) perceived exertion according to the Borg scale and (ii) the training HR range established individually for each patient. In line with the standards, the assumption was that patients should not exceed perceived moderate exertion during the ET (i.e. a score of 11 on the Borg scale).

Interventions Description of home‐based cardiac rehabilitation: The Care Assessment Platform of Cardiac Rehabilitation (CAP‐CR) platform used a smartphone for health and exercise monitoring, and delivery of motivational and educational materials to participants via text messages and pre‐installed audio and video files (including understanding cardiovascular disease symptoms and management). The platform included a web portal with participant data for mentors to provide weekly consultations. Each participant was equipped with a smartphone pre‐installed with health diary and activity monitoring applications; blood pressure monitor; and weight scale. Activity monitoring (step number, duration and intensity) was automatic through the phone’s in‐built accelerometer. Participants were advised to make daily health diary entries: weight, BP, sleep duration and quality, exercise other than automatically monitored steps, stress, meals and, if relevant, alcohol consumption and smoking. Mentors reviewed updated data prior to weekly consultations.

Interventions Both groups exercised 3 times per week for 12 weeks at 60‐70% HR reserve, plus peripheral muscle resistance training (50% 1RM).
Home‐based:
Home‐based training comprised walking (three times a week for 30 min) in which patients were instructed to maintain the target HR, combined with resistance exercises guided by an illustrated instruction manual for the upper limbs (elbow flexion and extension, and shoulder flexion and abduction) and lower limbs (hip flexion, extension and abduction, knee extension, and plantar flexion) using free weights. The exercise intensity to initiate the programme was one set of ten repetitions that followed a final progression to three sets of ten repetitions for each exercise with 50% of 1RM adjusted monthly over the training period. Free weights were provided for each patient according to the assessments. The patients were trained at least once per month with physiotherapist supervision, and the adherence and HR reached during the walks were monitored on a diary filled by the patients. Furthermore, the researcher made weekly phone calls to stimulate patients to continue performing daily exercises, to screen exercise adherence, and to answer possible doubts.

Interventions Individually determined CR programmes will be implemented in both study groups based on the participants’ referral diagnosis, physical fitness level and expected training goals. All participants will undertake a 12‐week, exercise‐based CR programme, including three training sessions of 60 min/week. All participants will perform aerobic training at 70% of their maximal heart rate, as obtained from cardiopulmonary exercise testing (CPET) for 20 min plus 20 min for strengthening and balance training. Exercise will be prescribed individually, according to the results of the baseline CPET and to the frequency, intensity, time (duration) and type of exercise model. Each exercise circuit will consist of 20 structured stations for aerobic, strength and balance training of 2‐min duration/station.
Home‐based (telerehab):
Participants will receive a 12‐week exercise‐based rehabilitation programme, remotely monitored. The TELE‐CR group will undertake three training sessions (or more if needed) in the hospital’s outpatient clinic for familiarisation with the use of the wearable sensors, the uploading of the training data to the web application (Polar Flow) and the exercising within their individually determined exercise intensity. Following the training period, TELE‐CR participants will be lent a Polar H10 chest strap that records HR data and a sports wristwatch (Polar M430, Kempele, Finland) and will proceed with the telerehabilitation programme at their homes. Participants in the TELE‐CR group will be exercising in groups of up to maximum five participants in each session. Real‐time supervision of this group‐based exercise session by a specialised physiotherapist will be implemented via videoconference web platforms or applications. At the end of every training session, patients will upload training data to the web platform (Polar Flow) via Bluetooth or USB connection. CR‐specialised staff from the corresponding hospital will have access to all patients’ accounts to monitor successful data uploading, assess the collected data and provide them with training feedback once a week via telephone video calls. Participants will wear an accelerometer.

Interventions After completing the 12‐week intervention, all patients were supported in their independent continuation and physical exercise adherence. No further contact was made during the following period of 1 year to ensure compliance after the intervention.
Home‐based:
The intervention was based on the principles of II phase of CR and consisted of regular physical exercise in the patient’s home environment and teleconsultations. Two mandatory training sessions initiated home‐based CR at the clinic under a physiotherapist’s guidance and a cardiologist’s supervision. During the pilot sessions, the patients were instructed how to exercise (load time, intensity) and were lent the HR Polar M430 wrist monitor (Kempele, Finland). The home‐based CR programme consisted of physical exercise 3 times a week, for 60 minutes at an intensity of 70‐80% of heart rate reserve. Once a week, each patient received a telephone consultation (feedback, motivation, education) based on the telemonitoring. Using the Global Position System, the physiotherapist supervised patient’s training sections and gave telephone feedback once a week.

Differences between protocol and review

Previous updates:

To reflect current practice and terminology, “percutaneous transluminal coronary angioplasty” (PTCA) was replaced by “percutaneous coronary intervention” (PCI), a term which encompasses the use of balloons, stents and atherectomy.

The order of primary and secondary outcomes has been updated, for clarity.

Due to the increase in the number of studies included in this review, we undertook meta‐regression analysis to examine potential treatment effect modifiers and the text has been updated to reflect this change.

We created a Summary of findings table using the following outcomes: total mortality, exercise capacity, withdrawal and health‐related quality of life.

This most recent update:

In the most recent version of this review, we have added digital/telehealth platforms to our inclusion definition of home‐based cardiac rehabilitation.

Contributions of authors

JA, CEC, HD, STJMcD, SM undertook the study selection for this update.
