This study compares two ways to keep blood flowing during open surgery for a large aneurysm in the chest and belly. About 236 adults will be randomly assigned to one of two heart-lung machine techniques. Researchers will track serious complications like death, stroke, kidney fail…

This study looks at whether using a CPAP machine for sleep apnea after a heart procedure (catheter ablation) can help prevent atrial fibrillation from coming back. About 658 adults with both conditions will be randomly assigned to use CPAP for a year or receive usual care. The go…

This study tests whether Yufeng Ningxin, a traditional Chinese medicine, can safely lower blood pressure in adults with mild hypertension. About 350 people aged 18-65 with untreated or washed-out high blood pressure will receive either the herbal tablet or a placebo for 8 weeks. …

This study looks at two different ways to use a heart-lung machine (ECMO) during high-risk heart procedures. One method sets up the machine just in case it's needed, while the other uses it from the start. The goal is to see which approach leads to fewer serious problems like dea…

This study tests whether a digital remote-management platform can help doctors better adjust heart failure medications after patients leave the hospital. About 252 adults with heart failure and reduced pumping function will use the platform to report symptoms and vital signs, wit…

This study tests whether giving extra fluids (saline) through an IV during and after a heart procedure called pulsed field ablation can prevent acute kidney injury. The procedure is used to treat atrial fibrillation, a common heart rhythm problem, but can sometimes harm the kidne…

This study tests a new surgical method called arch-clamping under mild hypothermia for people with a life-threatening tear in the aorta (acute type A aortic dissection). The trial will enroll 306 adults across 7 hospitals in China, comparing the new technique to standard approach…

This study looks at whether placing a special balloon pump (IABP) early after starting ECMO can improve survival in adults with cardiogenic shock—a life-threatening condition where the heart can't pump enough blood. About 358 participants will be randomly assigned to get the ball…

This study tests whether a catheter ablation procedure can reduce severe mitral valve leakage in people with persistent atrial fibrillation (a type of irregular heartbeat). About 146 adults aged 18-80 with both conditions will either get the ablation plus standard care or just st…

This study tests a procedure called cardioneuroablation for people with a slow heart rate (bradycardia) caused by overactive vagal nerves. Doctors use a catheter to ablate (destroy) specific nerve clusters in the heart. The trial will enroll 188 participants aged 18-65 and measur…

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 aged 18-80 who have been on blood thinners for at least 2 months after ablation and have no signs of AF recurrenc…

This study looks at whether using a CPAP machine, sometimes with a mild sleep aid, can help lower blood pressure in people with both sleep apnea and high blood pressure. About 200 adults aged 18-70 will use CPAP every night for 3 months. Those with insomnia can also take trazodon…

This study tests a new circular-shaped catheter that uses pulsed field energy to treat atrial fibrillation and atrial flutter. About 150 adults will receive the procedure, guided by ultrasound inside the heart. The goal is to see if the catheter safely and effectively blocks abno…

This study tests whether adding the blood thinner tirofiban after standard clot-busting treatment helps people with acute ischemic stroke recover better. About 976 adults whose stroke symptoms don't improve enough within an hour of initial treatment will receive either tirofiban …

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 tests whether placing stents in non-blocking but unstable heart plaques, along with intensive medication, reduces heart attacks and other cardiac events better than medication alone. About 2,190 adults with acute coronary syndrome will be randomly assigned to either st…

This study tests whether adding the drug tirofiban after a standard clot-removal procedure helps people recover better from a severe stroke caused by a blocked artery. About 716 adults will receive either tirofiban or a placebo right after the procedure. The main goal is to see i…

This study compares two surgical timings for babies born with Tetralogy of Fallot, a serious heart defect. One group gets corrective surgery within 28 days of birth, the other at the usual 3-6 months. Researchers will track deaths, reoperations, and recovery to see if earlier sur…

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 moderate blockages will be randomly assigned to either MCG-guided care or s…

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

This study tests whether a smartwatch-based program, combined with coaching from healthcare staff, can improve heart health in overweight or obese adults who have early signs of problems like high blood pressure or prediabetes. The program focuses on exercise and diet, and tracks…

This study looks at whether a procedure called catheter ablation can improve quality of life for people aged 80 and older who have a heart rhythm problem called atrial fibrillation. Half of the 182 participants will get the real procedure, and half will get a fake one (sham) to s…

This study is a registry that will follow 4,000 people in China who are having a procedure called catheter ablation to treat atrial fibrillation or ventricular tachycardia. The goal is to see how well the procedure works over the long term and how safe it is. Participants will be…

This study is looking for clues in the blood that could predict if a person's heart will change shape or develop serious problems after a major heart attack. Researchers will collect blood samples and perform heart ultrasounds on 1,000 patients over six months. The goal is to fin…

This study compares a 7-day AI-enhanced single-lead ECG patch against routine 12-lead ECGs to detect new atrial fibrillation in 15,360 adults aged 60+ in rural China. The goal is to see if longer, smarter monitoring catches more cases and reduces deaths, strokes, and heart failur…

This study will follow 30,000 people aged 60 and older in rural China for up to 10 years. Researchers want to see if a comprehensive program—including medication, lifestyle changes, health education, and regular check-ups with a 7-day heart monitor—can lower the number of heart a…
