This study looks at how knowing you have an unruptured brain aneurysm affects your mental health, and whether getting it treated or just monitoring it makes a difference. Researchers will follow 120 people with unruptured aneurysms, comparing those who have surgery or a less inva…

This study follows 100 people with severe narrowing of brain arteries to understand why some develop memory and thinking problems. Participants receive either standard medications or a procedure to open the artery. Researchers will track changes in memory and stroke risk over tim…

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 is collecting information from up to 10,000 people who receive BALT medical devices for conditions like brain aneurysms, stroke, and blocked arteries. Researchers will track how well the devices work and if any safety issues arise during routine care. The goal is to ga…

This study will follow 5,000 people who receive newer endovascular devices (like coils, stents, or flow diverters) to treat a brain aneurysm. Researchers want to see how often the aneurysm comes back and what factors, such as smoking, might play a role. The goal is to improve saf…

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…
