This study aims to see if voice recordings from a smartphone can help detect heart disease. Researchers will collect voice samples and health data from up to 1 million adults using the Mayo Clinic app. No treatment is given; the goal is to gather information for future AI tools.

This study uses artificial intelligence to analyze data from 21,000 patients who had heart valve procedures. The goal is to make AI tools that can predict surgery outcomes, like which device to use and risks of complications, with over 90% accuracy. This is a non-interventional s…

This study looks at 48 people with chronic leg swelling to find out why some respond to compression therapy and others don't. Participants will have an MRI and genetic testing to measure fat, muscle, and fluid in their legs. The goal is to better understand the condition, not to …

This study involves 70 adults with severe heart valve disease who are already scheduled for a routine heart catheterization. Researchers will use special catheters to measure how well the right side of the heart works with the lungs. The goal is to see if simpler, non-invasive te…

This study from King's College London focuses on how to better identify early skin changes from chronic venous insufficiency (CVI) in people with dark skin tones. Researchers will interview patients about their experiences and test new assessment techniques, like using touch and …

This observational study will follow 1900 people with moderate mixed aortic valve disease (a combination of aortic stenosis and regurgitation) to see how symptoms and heart function relate to survival and the need for valve replacement. Researchers hope to identify which patients…

This study is testing whether a smartwatch, combined with artificial intelligence and remote doctor check-ins, can help detect heart issues like atrial fibrillation and unstable angina earlier than usual. Researchers at the University of Sao Paulo will enroll 520 adults with hear…

This study is observing 900 adults in Greece who have both chronic obstructive pulmonary disease (COPD) and at least one heart condition. Researchers will track their health for two years, recording lung flare-ups, heart complications, hospital visits, and quality of life. The go…

This study looks at fetal cells that remain in a mother's blood after pregnancy, called fetal microchimeric cells, in women with chronic skin ulcers like venous or diabetic ulcers. Researchers will analyze these cells' genetic activity to see if they might help with wound healing…

This global registry will follow 800 patients receiving a new, less-invasive tricuspid valve replacement (TTVR) for leaky heart valves. Researchers aim to track complications like pacemaker needs and how well the valve works over time. The study does not test a new drug but gathe…

The European Venous Registry (EVeR) is collecting data from 100 patients with deep vein disease in the legs to track how different treatments work over 10 years. Researchers will measure symptoms and quality of life to find out which approaches are most effective. This is an obse…
