Could short bursts of intense exercise boost heart recovery better than steady workouts?
NCT ID NCT07619664
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two supervised treadmill exercise programs for people recovering from coronary artery disease or a heart procedure. One group does high-intensity interval training (HIIT) — short, hard efforts with rest periods — while the other does moderate-intensity continuous training (MICT) — steady, moderate exercise. Researchers will measure changes in heart function, walking ability, and cholesterol levels to see which approach works better.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- High-Intensity Interval Training (HIIT) and Moderate-Intensity Continuous Training (MICT)
- What this could lead to
- If HIIT proves superior, it could become a standard exercise option in cardiac rehab, potentially improving heart function and fitness more efficiently than traditional moderate exercise.
- What could go wrong
- This is a small, early-stage trial with 66 participants, so results may not apply to all heart patients. HIIT is intense and may not be suitable for everyone, even with medical clearance.
