Comparing Intensive and Traditional Cardiac Rehabilitation Programs

Multi-Center Randomized Study of Clinical and Inflammatory Outcomes in Intensive Cardiac Rehabilitation and Traditional Cardiac Rehabilitation Programs (CREDIBLE Study)

Not applicable Interventional Pritikin ICR · NCT06424119

This study is testing if an Intensive Cardiac Rehabilitation program, with or without home-delivered food, works better than a Traditional Cardiac Rehabilitation program for people recovering from heart issues.

What this trial studies

This prospective study evaluates the benefits of an Intensive Cardiac Rehabilitation (ICR) program compared to a Traditional Cardiac Rehabilitation (TCR) program, focusing on readmission costs and cardiovascular outcomes. Participants will be randomized into three groups: one receiving ICR with home-delivered food, one receiving ICR without food, and one receiving TCR. The study will measure various health outcomes, including major adverse cardiovascular events and improvements in biomarkers, at multiple time points. The goal is to determine if ICR provides superior benefits over TCR.

Who should consider this trial

Good fit: Ideal candidates include patients eligible for Intensive Cardiac Rehabilitation following specific cardiovascular events such as myocardial infarction or coronary artery bypass.

Not a fit: Patients with a life expectancy of under 2 years or significant co-morbidities that limit participation may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved cardiovascular outcomes and reduced healthcare costs for patients undergoing cardiac rehabilitation.

How similar studies have performed: Other studies have shown promising results with intensive rehabilitation approaches, suggesting potential for success in this study as well.
