This study is testing whether taking fecal microbiota transplants (FMT) in capsule form can reduce frailty and improve overall health in people aged 70 to 85. The idea is that restoring a healthier mix of gut bacteria might slow down aging and lower the risk of age-related diseas…

This study compares two treatments for idiopathic hyperaldosteronism (IHA), a condition where the adrenal glands make too much of a hormone that raises blood pressure. One treatment is a daily pill (spironolactone), and the other is a procedure called superselective adrenal arter…

This study tests a special anesthesia plan called NeuroFirst, designed to protect the brain during heart surgery. About 912 adults aged 60 and older will be randomly assigned to receive either NeuroFirst or standard care. The goal is to see if NeuroFirst reduces silent brain infa…

This study tests a new way to replace a narrowed heart valve (aortic stenosis) using a tube inserted through the armpit, guided only by ultrasound instead of X-rays. About 20 people with severe symptoms will be enrolled to see if this approach is safe and works well. If successfu…

This study looks at the best way to use blood thinners after a minimally invasive heart valve repair (TEER) in people with mitral regurgitation who also need long-term anticoagulation. About 880 participants will be randomly assigned to different blood-thinning strategies. The ma…

This study looks at the best way to use blood thinners after a minimally invasive heart valve repair (called TEER) in people with mitral regurgitation, a common heart valve problem. About 1,032 participants who do not need long-term blood thinners will be randomly assigned to dif…

This study tests if a new biodegradable heart implant can reduce migraine days better than a standard metal implant in people with a common heart hole called PFO. About 400 adults aged 18-65 with frequent migraines and PFO will receive one of the two implants. The goal is to see …

This study aims to improve how doctors diagnose and predict the course of rare heart muscle diseases (cardiomyopathies) using advanced MRI scans. Researchers will enroll 1000 people with suspected rare cardiomyopathies to test new imaging methods. The goal is to provide clearer, …

This study looks at a test called adrenal venous sampling (AVS) used in people with primary aldosteronism, a condition where the adrenal glands make too much of a hormone that raises blood pressure. Researchers will follow 5,000 patients to see how well AVS guides treatment and a…

This study will use advanced MRI scans to measure heart tissue in 2000 people with different heart conditions, like heart attacks and cardiomyopathies. The goal is to create a reference guide for doctors to interpret these scans and see if a simpler method without contrast dye wo…

This study looks at whether detailed heart MRI scans can help predict future heart attacks, strokes, or other serious heart events in people with ischemic heart disease. Researchers will review medical records from 1000 adults who already had a heart MRI. The goal is to improve r…

This study looks at the best time for patients to get up and walk after a leg artery procedure that uses a special closure device called ProGlide. The goal is to find a time that is both safe and helps patients recover faster. About 300 adults will be randomly assigned to differe…

This study looks at whether MRI scans can help predict serious heart events in people who have or need a pacemaker, defibrillator, or similar device. Researchers will follow 1,500 adults over time to see if MRI findings can identify who is at higher risk for sudden cardiac death …

This study looks at a rare heart condition called non-dilated left ventricular cardiomyopathy (NDLVC), where the heart muscle is abnormal but not enlarged. Researchers will review past medical records and heart MRI scans from 1,000 patients to see which scan findings are linked t…
