CORONARY MICROVASCULAR DISEASE

This study tests whether a 36-session cardiac rehabilitation program, added to standard medications, can improve quality of life in people with coronary microvascular disease (small vessel heart disease). About 204 participants with chest pain and confirmed microvascular dysfunct…

This study tests a small mesh device, called the coronary sinus reducer, in 50 people with chest pain caused by tiny heart vessel disease. The device is placed in a heart vein to increase pressure and improve blood flow. Researchers will measure changes in blood flow and daily ch…

This study follows over 1,000 people with suspected coronary artery disease to see if special blood flow measurements in the heart's tiny vessels can predict future heart attacks, need for repeat procedures, or hospital stays. Participants undergo standard heart catheterization w…

This study looks at why some women with heart disease symptoms have clear major arteries but still have chest pain or stress test issues. Researchers think tiny heart vessels or blood clotting problems may be the cause. About 206 women will have extra tests during their heart cat…

This study follows over 670 people with chest pain but no major blockages in their heart arteries, focusing on disease in the tiny blood vessels (coronary microvascular disease). Researchers use a special technique to measure blood flow and will track heart-related events like he…
