This study tests a digital tool called 'Smart family doctor' that uses artificial intelligence to help people who have had heart bypass or stent surgery better control their blood pressure, blood sugar, and cholesterol. About 951 adults aged 18-80 will be randomly assigned to use…

This study compares two types of drug-coated balloons used to open blocked heart arteries in people with acute coronary syndrome (a serious heart condition). About 60 adults will receive either a sirolimus-coated or paclitaxel-coated balloon during a procedure. The main goal is t…

This study tests whether closing a small pouch in the heart (the left atrial appendage) during valve surgery can prevent silent strokes in 100 adults without atrial fibrillation. Participants will have brain scans after surgery to check for hidden damage. The goal is to find a si…

This study tests whether using only ultrasound (echo) to guide a minimally invasive heart valve replacement is as effective as the standard method that uses both X-ray and ultrasound. The goal is to reduce the risk of kidney damage from contrast dye and lower radiation exposure. …

This study compares two imaging techniques—CT-FFR and QFR—to see which better guides treatment decisions for people with coronary artery disease. About 1,400 participants with moderate blockages will be randomly assigned to one of the two methods. The goal is to find out which ap…

This study develops and tests a privacy-protecting AI system that reads patient admission notes to classify four types of coronary artery disease, including heart attacks. Researchers will check how accurately the tool works across different hospitals and languages, and whether i…

This study will follow 6,000 people in China who have both coronary heart disease and a leaky heart valve caused by a heart attack (ischemic mitral regurgitation). Researchers will collect medical data and track health outcomes for two years to learn how the disease progresses an…

This study looks at 421 people who are getting a heart device (ICD) to prevent sudden cardiac death. Researchers will use AI to combine information about muscle strength, body scans, and blood tests to build a better way to predict who is at highest risk. The study does not test …

This study compares two ways of making treatment decisions for people with severe blockages in all three main heart arteries who also have diabetes. One group gets a real-time online discussion among heart experts during a procedure, while the other gets usual care. The goal is t…
