This study tests whether using a wearable device (like an Apple Watch) to monitor patients remotely can help doctors adjust heart failure medications more effectively. It includes 400 adults with both heart failure and atrial fibrillation. The goal is to improve medication use an…

This study tests a procedure called TEER, which uses a clip to repair a leaky heart valve in people with a specific type of mitral regurgitation caused by atrial issues. About 400 adults with moderate-to-severe symptoms despite medication will be randomly assigned to get the clip…

This study tests a new guiding catheter designed for carotid artery stenting through the wrist (transradial access). The goal is to see if this catheter helps doctors successfully place a stent in the carotid artery within 10 minutes, while reducing complications and radiation ex…

This study compares a heart procedure called catheter ablation to usual medical care for people with atrial fibrillation (an irregular heartbeat) who have also had a brain bleed (intracerebral hemorrhage). The goal is to see if ablation reduces the risk of death, stroke, or blood…

This study looks at 3,000 elderly diabetic patients having heart surgery with a heart-lung machine. It compares tight versus liberal blood sugar control during the procedure to see which approach reduces serious complications like death, kidney injury, heart attack, or stroke. Th…

This study tests whether a smartphone app powered by artificial intelligence can help adults recover better after heart surgery. 500 patients will either use the app plus standard care or standard care alone. The app gives personalized advice on medications, rehab, and warning si…

This study looks at whether using a CPAP machine for 12 months after a heart procedure (catheter ablation) can lower the chance of atrial fibrillation coming back in people who also have obstructive sleep apnea. About 658 adults aged 18-75 with both conditions will be randomly as…

This study tests whether using a smartphone app for remote health management can reduce the risk of heart disease better than regular doctor visits. About 790 adults with high heart disease risk will be split into two groups: one using the app and one getting usual care. The goal…

This study tests whether a class of cholesterol-lowering drugs called PCSK9 inhibitors can prevent or delay the worsening of calcific aortic stenosis, a condition where the heart valve becomes stiff and narrow. Researchers will enroll 160 adults with mild to moderate disease who …

This study tests whether a smartphone app can help people with coronary heart disease better control their blood pressure and cholesterol after a heart procedure. About 792 adults who have had a stent placed will either use the app or receive standard care. The goal is to see if …

This study tests a device called CA330 that is used during heart surgery to filter the blood. The goal is to see if it can lower the risk of severe bleeding in patients who take blood thinners and need emergency heart surgery. About 120 adults will be randomly assigned to receive…

This study tests whether taking a low dose of colchicine (0.5 mg daily) after coronary artery bypass grafting (CABG) can reduce the chance of graft failure. About 622 adults who recently had bypass surgery will receive either colchicine or a placebo for 24 months. The main goal i…

This study looks at whether gently cooling the body (mild hypothermia) can reduce heart damage in people having a severe heart attack complicated by shock. Participants will already be on a heart-lung machine (ECMO) and undergo emergency artery-opening treatment. The goal is to s…

This study looks at whether new blood tests can find dangerous blood clots in the lungs (pulmonary embolism) faster and more accurately. Researchers will test 200 newly diagnosed patients and track their recovery. The goal is to catch these clots earlier, reduce deaths, and impro…

This study tests a new tool called UFR that uses ultrasound images to measure blockages in heart arteries during a heart attack. The goal is to see if it can accurately predict which blockages are serious, so patients don't need to return for a second invasive procedure 30 days l…

This study aims to see if a simple, non-invasive breath test can detect high cholesterol early. Researchers will collect breath samples from 280 healthy people and people with high cholesterol. They will analyze the breath for unique chemical patterns to see if the test is accura…

This study looks at whether using conscious sedation (being awake but relaxed) is safer than general anesthesia (being fully asleep) during a heart procedure called pulsed-field ablation for people with a type of irregular heartbeat called paroxysmal atrial fibrillation. About 22…

This study will enroll 1,000 people who have had a severe heart attack complicated by cardiogenic shock, a life-threatening condition where the heart cannot pump enough blood. Researchers will test a new team-based care system designed for Chinese hospitals and collect data to bu…

This study aims to create a risk prediction model for coronary artery disease by combining heart imaging (like CT scans) with blood tests (like cholesterol levels). Researchers will analyze data from over 10,000 participants to identify who is at high risk for heart attacks or ot…

This study will follow over 11,000 adults with sleep-disordered breathing for up to 5 years. Researchers want to learn more about the condition, find better ways to predict risks, and improve treatment plans. Participants will provide health data and samples to help build a natio…

This study looks at 1,200 adults after heart surgery to see if large swings in blood pressure and poor blood flow to tissues are linked to serious problems like stroke, heart attack, or kidney failure. Researchers will monitor patients in the ICU for at least 12 hours after surge…

This study will follow 1800 adults with coronary artery disease who have had a stent placed to open a blocked heart artery. Researchers want to see if special measurements from X-ray images and a camera inside the artery can better predict future heart problems like heart attacks…

This study looks at how low oxygen levels during sleep from obstructive sleep apnea (OSA) may damage tiny blood vessels in the heart. Researchers will follow 560 adults with suspected heart issues to see if sleep apnea patterns predict future heart problems better than standard t…

This study follows 1500 adults with ventricular tachycardia (a fast heart rhythm) to compare long-term risks like death or repeat episodes. Some patients get catheter ablation, others get medication or an ICD. The goal is to learn which approach works better over time.

This study looks at 212 heart disease patients who take blood thinners and have sudden upper stomach bleeding. It compares getting an endoscopy within 12 hours versus waiting 12-24 hours to see which timing leads to fewer heart complications. The goal is to find the safest approa…

This study aims to build a smart system that uses artificial intelligence and wearable devices to predict heart attacks in high-risk people. Researchers will enroll 3000 participants with known heart disease or risk factors like diabetes or kidney disease. The goal is to catch wa…
