This study looks at two different ways to use a heart-lung machine (ECMO) during high-risk heart procedures. The goal is to see if having the machine ready but not connected until needed works better than connecting it before the procedure starts. The trial involves 176 adults wi…

This study tests whether adding the drug tirofiban to a standard clot-removal procedure helps people recover better after a severe stroke caused by hardened arteries. About 716 adults who have had a stroke within the past 24 hours will receive either tirofiban or a placebo after …

This study looks at how well CPAP therapy lowers blood pressure in people with obstructive sleep apnea and high blood pressure. Researchers will also test if adding a low-dose sleep aid (trazodone or zolpidem) for those with insomnia helps even more. About 200 adults aged 18–70 w…

This study tests a digital platform that helps doctors adjust heart failure medications remotely. About 252 adults with heart failure and reduced pumping function will use the app to report symptoms and vital signs, while an algorithm suggests medication changes. The goal is to s…

This study tests whether adding a drug called tirofiban after standard clot-busting treatment helps people recover better from a severe stroke. About 976 adults who did not improve enough after initial treatment will receive either tirofiban or a placebo for 24 hours. The main go…

This study tests whether placing a stent in artery plaques that are vulnerable but not yet blocking blood flow can prevent future heart attacks or chest pain. About 2,190 people with coronary artery disease will either get a stent plus intensive drug therapy or drugs alone. The g…

This study tests a new surgical approach for a severe tear in the main artery (acute type A aortic dissection). About 306 adults will be randomly assigned to one of three surgical methods, using different cooling levels during the operation. The goal is to see if the new techniqu…

This study tests whether a catheter ablation procedure can reduce severe mitral valve leakage in people with persistent atrial fibrillation. About 146 adults aged 18-80 with both conditions will be randomly assigned to either ablation or standard drug therapy. The main goal is to…

This study compares two surgical timings for newborns with Tetralogy of Fallot, a serious heart defect. About 160 full-term babies will be randomly assigned to receive repair within 28 days of birth or at the standard 3-6 months. The goal is to see if earlier surgery reduces deat…

This study tests a procedure called cardioneuroablation, which uses a catheter to target heart nerves that cause a slow heart rate (bradycardia). The goal is to see if this can improve symptoms like dizziness and fatigue without needing a permanent pacemaker. The study will enrol…

This study compares two methods to protect the brain during a procedure to open a narrowed neck artery (carotid stenting). The standard method uses a small filter to catch debris, but some particles may still reach the brain. The new method adds a balloon that temporarily stops b…

This study is testing a new circular-shaped catheter that uses pulsed field ablation to treat atrial flutter, a type of irregular heartbeat. Researchers want to see if it is safe and effective. About 150 adults with atrial fibrillation or flutter will take part. The procedure is …

This study tests whether giving extra fluids through an IV before and after a new type of heart procedure (pulsed field ablation) can prevent kidney injury in people with atrial fibrillation. About 290 adults will be randomly assigned to receive either standard care or extra flui…

This study compares two ways of using a heart-lung machine during open surgery for a thoracoabdominal aortic aneurysm (a bulge in the main artery in the chest and belly). About 236 adults from four hospitals in China will be randomly assigned to one of two bypass techniques. The …

This study looks at whether people with atrial fibrillation (AF) can safely stop taking blood thinners after a successful heart ablation procedure. About 4,100 adults who have been free of AF for at least 2 months after ablation will either stop or continue their blood thinner. E…

This study tests whether adding an intra-aortic balloon pump (IABP) early after starting a heart-lung machine (VA-ECMO) helps people in severe cardiogenic shock survive. About 358 adults will be randomly assigned to get the balloon pump or standard care. The main goal is to see i…

This study tests a special mattress that tracks heart rate, breathing, body temperature, and movement without any wires or sensors touching the patient. It involves 1,100 adults hospitalized for heart problems. The goal is to see if this non-contact system can help doctors monito…

This study tests whether a non-invasive heart scan called magnetocardiography (MCG) can help doctors decide the best treatment for people with stable coronary artery disease. About 1,300 participants with partially blocked arteries will be randomly assigned to either MCG-guided c…

This study tests whether using a smart wearable device (like a fitness tracker) along with health coaching can improve heart health in overweight or obese adults who have early warning signs like slightly high blood pressure, blood sugar, or cholesterol. About 1,400 participants …

This study looks at whether a procedure called catheter ablation can improve quality of life in people aged 80 and older who have atrial fibrillation (an irregular heartbeat). Participants will be randomly assigned to receive either the real procedure or a sham (fake) procedure. …

This study looks at blood samples from 1,000 people who had a major heart attack to find markers that predict if the heart will become weak or if future heart problems will occur. The goal is to better understand who is at risk and why, so doctors can personalize follow-up care. …

This study will follow 30,000 people aged 60 and older in Qujiang, China, who have chronic heart conditions like high blood pressure, heart failure, or atrial fibrillation. Researchers want to see if a program combining medication, lifestyle advice, education, and regular check-u…

This study is testing whether a wearable, AI-enhanced heart monitor worn for 7 days can find more cases of atrial fibrillation (an irregular heartbeat that raises stroke risk) than usual care in people aged 60 and older living in rural China. About 15,360 participants from 128 vi…
