High-Intensity interval training vs home-based rehab after coronary bypass grafting

Official title: Effect of High-Intensity Interval Training Versus Home-Based Rehabilitation Program on Peak Metabolic Equivalents On Patients Underwent Coronary Artery Bypass Graft Surgery

Run by Kafrelsheikh University · NCT07775742 · Data updated 2026-11-12

This trial tests whether high-intensity interval training or a home-based cardiac rehab program can better improve peak exercise capacity in people who had CABG surgery.

Is this trial a fit for you?

Likely a good fit

Adults around age 55 who are clinically stable after CABG, at low-to-moderate risk, and able to participate in a structured exercise program.

Probably not a fit

Those with ejection fraction below 40%, significant comorbidities affecting mobility or mental health disorders, or contraindications to exercise may not benefit.

What this trial studies

This interventional study compares two rehabilitation approaches for adults recovering from coronary artery bypass grafting. It evaluates changes in peak metabolic equivalents (METs) after completing a structured high-intensity interval training program or a home-based cardiac rehabilitation program. A control condition of no intervention is included for comparison. Eligible participants are adults around 55 years old, stable, and at low-to-moderate risk, who have completed at least one month of post-surgical recovery. The study aims to determine which approach yields greater improvement in functional fitness and how outcomes compare between the two active interventions.

Why it matters

Potential benefit: If successful, participants may achieve greater improvements in aerobic capacity and overall functional health after CABG.

How similar studies have gone: Previous research supports the safety and effectiveness of cardiac rehabilitation, including HIIT, for improving fitness in CAD patients, though long-term benefits vary.
