Comparing the effects of high intensity and moderate intensity exercise on heart rate variability after a heart attack
Acute Effects of High Intensity Interval Training (HIIT) vs. Moderate Intensity Continuous Training (MICT) on Heart Rate Variability Parameters in Patients After Myocardial Infarction
NA · University Medical Centre Ljubljana · NCT06437145
This study is testing whether high intensity exercise or moderate exercise helps improve heart health by looking at heart rate changes in people who have had a heart attack.

What this trial studies
This study investigates the acute effects of high intensity interval training (HIIT) versus moderate intensity continuous training (MICT) on heart rate variability (HRV) in patients who have experienced a myocardial infarction. Participants will engage in both types of exercise in a randomized order, with a minimum 48-hour break between sessions. Heart rate data will be collected through high-resolution ECG recordings before and immediately after each exercise session to assess changes in HRV. The goal is to better understand how different exercise intensities impact heart health post-heart attack.
Who should consider this trial
Good fit: Ideal candidates for this study are individuals who have had a myocardial infarction within the last 120 days and are in sinus rhythm.
Not a fit: Patients with contraindications for exercise training, uncontrolled dysrhythmias, advanced heart failure, cognitive impairment, or those who are pregnant may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could provide insights into optimal exercise regimens that enhance heart recovery and improve HRV in post-myocardial infarction patients.
How similar studies have performed: While many studies have shown chronic benefits of exercise on HRV, this investigation into the acute effects of different exercise intensities is relatively novel and less explored.
