NCT ID NCT04190394
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study compared two types of exercise training for people who had a heart attack: continuous moderate exercise and intermittent high-intensity exercise. One hundred participants completed an 8-week program, and researchers used ultrasound to measure changes in heart function. The goal was to see if one type of exercise improves heart muscle movement more than the other.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- exercise training program
- What this could lead to
- If successful, this could help doctors choose the best type of exercise program for heart attack recovery.
- What could go wrong
- This is a small, completed study with 100 participants, so results may not apply to everyone. It compares two exercise types, not a new drug or treatment.
