TeleheartCR vs. Clinic-Based Cardiac Rehabilitation After Acute Coronary Syndrome

Summary

Cardiac 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.

Detailed Description

Over 1 million patients are hospitalized annually in the United States for an acute coronary syndrome (ACS; myocardial infarction or unstable angina). Accordingly, CR is recognized as a Class I, Level A recommendation for secondary prevention in ACS survivors. Yet less than a quarter of eligible cardiac patients utilize CR in the US. Even among patients who initiate CR, fewer attend all prescribed CR sessions, with lower rates observed among those with low socioeconomic status (SES), and racial and ethnic minoritized groups. Low and disparate CR adherence harms patients, as evidence suggests a dose-response relationship, such that each additional CR session attended reduces morbidity and mortality. Innovative program designs are needed to deliver sustained, equitable CR participation among ACS patients. The central hypothesis of this research study is that TeleheartCR will show greater program implementation (better adherence \[primary\], acceptability, and appropriateness) and will be just as effective (non-inferior pre- to post-intervention change in functional capacity \[primary\], health-related quality of life, and cardiorespiratory fitness) relative to clinic-based CR. The TeleheartCR program includes up to 36 sessions delivered through a combination of clinic-based and home-based sessions and is typically completed over approximately 12 weeks. To allow for scheduling flexibility and clinical considerations, participants may be allowed up to 6 months post-enrollment to complete the program and outcome assessments. To formally test the hypothesis, the investigator will conduct an adequately powered effectiveness-implementation hybrid type I randomized controlled trial (RCT) comparing the TeleheartCR program vs. clinic-based CR among ACS patients. Specifically, this study will determine the degree to which the TeleheartCR program improves CR adherence, clinical outcomes (e.g., functional capacity), and equitable cost/access (i.e., across SES, racial, and ethnic groups) relative to clinic-based CR among ACS patients.
