Study characteristics
Methods	Study design: RCT Country: Italy Dates participants recruited: NR Maximum follow‐up: 1 year Randomised after exercise tolerance test, 30 days after MI.
Participants	Inclusion criteria: participants aged 40 to 60 years with MI Exclusion criteria: more than one previous MI N randomised: total: 50; intervention: 25; comparator: 25 Diagnosis (% of participants): MI: 100% Age (mean ± SD): intervention: 50.1 ± 5.5; comparator: 50.1 ± 6.3 Percentage male: intervention: 100%; comparator: 100% Ethnicity: 100% Italians
Interventions	Intervention: 6 weeks physical activity programme Components: exercise Setting: NR Exercise programme modality: NR Length of session: NR Frequency: NR Intensity: NR Resistance training included? NR Total duration: 6 weeks Co‐interventions: NR Comparator: after discharge a simple plan of daily exercises (intensity ≤ 3 METs ) to perform at home Co‐interventions: NR
Outcomes	CV mortality
Source of funding
Conflicts of interest
Notes	Trained participants showed a better mid‐term prognosis than controls, but this could not be explained by the physical training procedure.
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Not reported.
Allocation concealment (selection bias)	Unclear risk	Not reported.
Blinding of outcome assessment (detection bias) All outcomes	Unclear risk	Blinding not described.
Incomplete outcome data (attrition bias) All outcomes	High risk	24% lost to follow‐up; no description of withdrawals or dropouts.
Selective reporting (reporting bias)	Low risk	All outcomes reported at all time points.
