Exercise program aims to reverse artery damage in heart patients
NCT ID NCT06579807
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is testing whether a 12-week supervised exercise program can improve artery health and reduce inflammation in people with coronary artery disease. Fifty patients aged 40-70 will do aerobic, resistance, and flexibility exercises three times a week. Researchers will measure artery thickness, blood vessel function, and blood markers of inflammation before and after the program.
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 (aerobic, resistance, and flexibility exercises)
- What this could lead to
- If successful, this could show that a structured exercise program improves artery health and reduces inflammation in people with coronary artery disease.
- What could go wrong
- This is a small, early-stage study with only 50 participants, so results may not apply to everyone. The exercise program is supervised and generally safe, but there is a small risk of injury or cardiac events during exercise.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Eligible CAD patients will be those aged 40 to 70 years, of both sexes, entering the cardiac rehabilitation program at HUPE. CAD will be defined as any acute coronary syndrome, including myocardial infarction with and without ST-segment elevation, and unstable angina (all defined by characteristic histories, electrocardiographic abnormalities, and cardiac enzyme abnormalities), or obstructive CAD diagnosed via coronary angiography (defined as ≥ 50% stenosis of any epicardial coronary artery) in patients with stable angina. * Healthy controls: adults aged 40 to 70 years, of both sexes, without CAD evidence. Exclusion Criteria: * diagnosis of heart failure, pulmonary disease, Chagas disease, or tuberculosis * regular physical exercise practice (≥ 3 days/week for 30 min) over the past 6 months * malnutrition (body mass index \[BMI\] \< 18.5 kg/m²) * smoking * obesity (BMI ≥ 30 kg/m²)
