Study name	An Internet‐based Cardiac Rehabilitation Enhancement (i‐CARE) Intervention to Support Self‐care of Patients With Coronary Artery Disease
Methods	RCT
Participants	Inclusion criteria: ≥ 18 years of age living in the community own a smartphone with internet access communicable in Cantonese type in Chinese or English with a confirmed diagnosis of CAD Exclusion criteria: enrolled to a structured centre‐based or home‐based cardiac rehabilitation program psychiatric problems impaired cognitive functioning (i.e. Abbreviated Mental Test ≤ 6) terminal disease with life expectancy < 1 year
Interventions	Intervention: participants in the intervention group will receive a 12‐week i‐CARE intervention, which will be designed to cover the core elements of CAD self‐care: self‐care maintenance, self‐care monitoring and self‐care management. The intervention will comprise: 1) a single individualised face‐to‐face session, and 2) an internet‐based intervention through a mobile application. Various behaviour change techniques will be used to increase the self‐efficacy of CAD patients in enacting self‐care behaviours. Comparator: participants will receive conventional care as arranged by hospital or community centres.
Outcomes	cardiovascular events, mortality, HRQoL
Starting date	May 2021
