This study tests a procedure called cardioneuroablation, which uses a catheter to destroy specific heart nerves that cause an abnormally slow heartbeat. The goal is to improve heart rate and reduce symptoms like fainting or dizziness. About 188 adults aged 18-65 with symptomatic …

This study looks at whether a procedure called catheter ablation can help people with persistent atrial fibrillation (an irregular heartbeat) who also have severe mitral regurgitation (a leaky heart valve). The goal is to see if ablation reduces the leakiness better than medicati…

This study tests whether operating within the first 28 days of life (neonatal repair) is safer and more effective than waiting until 3-6 months (infant repair) for babies born with Tetralogy of Fallot, a serious heart defect. About 160 full-term newborns weighing over 2.5 kg will…

This study looks at how well CPAP therapy lowers blood pressure in people with obstructive sleep apnea and high blood pressure. It also tests whether adding a mild sleep medication (trazodone or zolpidem) for those with insomnia can boost the blood pressure benefits. About 200 ad…

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 compares two ways of using ECMO (a heart-lung support machine) during high-risk heart procedures. One group gets ECMO set up and ready to use if needed, while the other gets it started before the procedure. The goal is to see which approach leads to fewer serious probl…

This study compares two methods to protect the brain during a procedure to open a narrowed neck artery. About 296 people with significant artery narrowing will be randomly assigned to receive either the standard filter alone or a filter plus a balloon that temporarily stops blood…

This study tests whether giving the blood thinner tirofiban right after a clot-removal procedure helps people recover better from a severe stroke caused by hardened arteries. About 716 adults who have had a major stroke will be randomly assigned to receive either tirofiban or a p…

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 whether adding a drug called tirofiban after standard clot-busting treatment helps people who had a stroke and aren't improving enough. About 976 adults will receive either tirofiban or a placebo for 24 hours, then standard care. The goal is to see if more people…

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 tests whether placing stents in non-blocking but vulnerable plaques, along with intensive drug therapy, reduces heart-related events more than drugs alone. About 2,190 adults with acute coronary syndrome will be randomly assigned to one of two groups. The goal is to se…

This study tests whether a smartphone or web-based platform can help doctors adjust heart failure medications more effectively than usual care. About 252 adults with heart failure and reduced pumping function will be randomly assigned to use the digital tool or receive standard f…

This study compares three surgical approaches for repairing a sudden tear in the main artery (acute type A aortic dissection) in 306 adults across 7 hospitals in China. The new method uses a clamp on the aortic arch under mild cooling, while the standard uses deeper cooling and a…

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). 236 adults from 4 hospitals in China will be randomly assigned to one of two bypass methods. The goal is to see which technique lead…

This study looks at a new circular-shaped catheter that uses pulsed energy to treat atrial fibrillation and atrial flutter. It is guided by a special ultrasound inside the heart to improve accuracy. Researchers want to see if it can safely and effectively restore normal heart rhy…

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 will be split into two groups: one where treatment is guided by MCG results, and…

This study is testing a special mattress that can check heart rate, breathing, temperature, and body position without touching the patient. It is designed for adults with heart disease who are staying in the hospital. The goal is to see if this smart mattress works as well as sta…

This study tests whether using a smart wearable device along with lifestyle coaching can improve heart health in 1,400 overweight or obese adults who have early signs of heart problems like high blood pressure or prediabetes. Participants will be tracked for 6 to 12 months to see…

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 is tracking 30,000 people aged 60 and older in rural China to see if a comprehensive program—combining medication, lifestyle advice, education, and heart monitoring—can lower the risk of heart attacks, strokes, and heart-related deaths. Participants will be followed fo…

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…
