RecruitingBehavioural interventionTeleheartCR vs. Clinic-Based Cardiac Rehabilitation After Acute Coronary SyndromeCardiac rehabilitation (CR) is an effective evidence-based intervention that improves outcomes in patients with acute coronary syndrome (ACS), but many eligible patients do not complete the program. A hybrid CR intervention that combines telehealth, home-based, and clinic-based components (TeleheartCR) may increase participation by addressing barriers to access while maintaining the functional capacity benefits of traditional CR. The purpose of this study is to conduct a randomized controlled trial comparing TeleheartCR with traditional clinic-based CR in patients with ACS to evaluate differences in program adherence and pre-to-post program change in functional capacity.
