Nonobstructive coronary artery disease

This pilot trial is testing whether a device called the Coronary Sinus Reducer can help people with angina (chest pain) who have no significant blockages in their coronary arteries. The device, shaped like an hourglass, is placed into a vein in the heart to improve blood flow. Th…

This study tests whether inclisiran, a drug given as a shot every 6 months, can reduce plaque buildup in the heart's arteries when added to standard statin therapy. About 608 adults with mild artery blockages (less than 50%) and no prior heart events will be randomly assigned to …

This study tests whether a combination of high-dose statins, blood pressure medications (ACE inhibitors or ARBs), and low-dose aspirin can reduce the risk of death, heart attack, stroke, or hospitalization in women who have chest pain or shortness of breath but no major blockages…

This study looks at people with Long COVID who have new chest pain but no blocked arteries. It tests whether a special heart function test can guide treatment to improve symptoms and quality of life. 108 participants will be randomly assigned to either treatment guided by the tes…

This study involves 500 people who have chest pain or other signs of heart trouble, but whose main heart arteries are not blocked. Researchers use special tools during a heart catheterization to measure tiny blood vessel function and look for hidden causes like microvascular dise…
