Can exercise rehab ease invisible heart pain?

This study is testing whether adding a supervised exercise program (cardiac rehabilitation) to standard medication can improve quality of life for people with coronary microvascular disease, a condition that causes chest pain despite clear arteries. About 204 patients with confirmed microvascular dysfunction and chest pain will be randomly assigned to receive either medication alone or medication plus a 36-session exercise program. The main goal is to see if the exercise program reduces chest pain frequency and improves patients' daily life after 4 months.
