This study tests whether using a smartphone app for remote health management can lower the risk of heart disease better than standard doctor visits. About 790 adults with a high 10-year risk of heart problems will be split into two groups: one using the app and one getting usual …

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 tests whether a class of cholesterol-lowering drugs called PCSK9 inhibitors can slow or prevent the worsening of calcific aortic stenosis, a condition where the heart valve becomes stiff and narrow. About 160 adults with mild-to-moderate disease will receive either the…

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 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 a smartphone app powered by artificial intelligence can help people recover better after heart surgery. 500 adults who had heart surgery will either use the app plus standard care or standard care alone. The app gives personalized advice on medications, r…

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 new, specially designed catheter for placing a stent in the carotid artery (a major neck artery) through a small incision in the wrist. The goal is to see if this new tool makes the procedure faster and safer than current methods. About 204 adults with signific…

This study looks at whether using wearable devices like the Apple Watch can help doctors remotely adjust medications for people with both heart failure and atrial fibrillation. About 400 participants will be split into two groups: one gets standard care, the other uses a smartwat…

This study tests a procedure called TEER, which uses a clip to repair a leaky mitral valve in people with a specific type of heart failure. The goal is to see if the procedure reduces the risk of death or worsening heart failure compared to standard medical therapy alone. About 4…

This study compares a heart procedure called catheter ablation to standard medical care for people with atrial fibrillation (an irregular heartbeat) who have also had a brain bleed. The goal is to see if ablation reduces the risk of death, stroke, or blood clots. About 646 adults…

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

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 reduces major complications like death, kidney injury, heart attack, or stroke. The goal is t…

This study aims to see if a new breath test can quickly and painlessly screen for high cholesterol. Researchers will collect breath samples from 280 healthy adults and those with high cholesterol to analyze the chemicals in their breath. If successful, this could lead to a simple…

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 right away, so patients don't need to return for a second invasive test 30 …

This study looks at whether new blood markers can help doctors diagnose and treat acute pulmonary embolism (a serious blood clot in the lungs) more quickly and accurately. Researchers will test 200 newly diagnosed patients and track their results before and after treatment. The g…

This study looks at 224 adults with a type of irregular heartbeat called paroxysmal atrial fibrillation who are getting a procedure called pulsed-field ablation. Half will receive lighter sedation (conscious sedation) and half will receive general anesthesia. The goal is to see w…

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…

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 12 hours and track outcomes f…

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 will track 1,000 people in China who have a severe heart attack complicated by cardiogenic shock, a life-threatening condition where the heart can't pump enough blood. Researchers want to see if a coordinated care system involving multiple specialists can improve survi…

This study will follow 11,100 adults with sleep-disordered breathing (like sleep apnea) for up to 5 years. Researchers will collect health data and samples to find better ways to predict risks, choose treatments, and personalize care. The goal is to improve long-term outcomes and…

This study aims to create a tool that combines heart scans and blood tests to better predict who is at high risk for serious heart problems like heart attacks. Researchers will look at data from over 10,000 people to build and test this risk prediction model. The goal is to help …

This study follows 1500 adults with ventricular tachycardia (a fast heart rhythm) to compare long-term risks like death or repeat episodes between those treated with catheter ablation and those managed with medications or an ICD. The goal is to understand which approach leads to …

This study looks at how low oxygen levels during sleep (from obstructive sleep apnea) are connected to problems in the tiny blood vessels of the heart. Researchers will monitor 560 adults with suspected heart issues using sleep tests and heart scans. The goal is to see if certain…

This study will observe 1,800 adults who have had a stent placed in a heart artery to see if new imaging and blood flow tests can better predict future heart problems. Researchers will use special computer analysis of X-ray images to measure blood flow and resistance in the arter…
