PERCUTANEOUS CORONARY INTERVENTION

This study tests a simple balloon inflation technique to modify blood clots during emergency heart artery opening. 100 heart attack patients will either get the balloon procedure or standard care. The goal is to see if this reduces damage to the heart muscle and improves recovery…

This study looks at a special stent (a small mesh tube) coated with a drug called sirolimus, used to open blocked heart arteries. Researchers will follow 300 adults who received this stent during a standard heart procedure to see how safe and effective it is over 5 years. The mai…

This study tests whether adding a Chinese herbal medicine called Qidan Xiaoke Granules to standard heart drugs can reduce major heart problems like heart attacks or repeat procedures in people who have had a stent placed. About 164 adults with coronary artery disease will take th…

This study tests whether Baduanjin, a gentle traditional Chinese exercise, helps people recover after heart bypass or stent surgery. Researchers will track 310 adults for up to a year to see if it lowers the risk of heart attacks, chest pain, or the need for more procedures. The …

This study tests whether a drug-coated balloon is as good as or better than a drug-eluting stent for people with multiple blocked heart arteries. About 892 adults with stable heart disease or recent heart attack will be randomly assigned to one of the two treatments. The goal is …

This study looks at whether people who had a heart procedure with a drug-coated balloon can safely stop taking antiplatelet drugs after 12 months. The goal is to see if stopping reduces bleeding risks while keeping the heart protected. About 1,000 adults who have been event-free …

This study compares two blood thinners, bivalirudin and heparin, used during a heart procedure called PCI in people with acute coronary syndrome who are at high risk of bleeding. About 5,270 participants will be randomly assigned to receive one of the two drugs. The goal is to se…

This study tests whether a smartphone app can help people with coronary heart disease better manage their blood pressure and cholesterol after having a stent placed. About 792 participants will either use the app for one year or receive usual care. The app reminds patients to che…

This study tests whether using mild electrical pulses on the diaphragm and belly muscles can improve breathing, heart function, and exercise ability in people who recently had a heart artery-opening procedure (angioplasty). 42 adults will receive either standard rehab plus this s…

This study tests whether applying an ice bag to the groin area after a heart procedure (called PCI) can reduce pain and bruising. Sixty adults who had the procedure through the femoral artery will receive ice therapy for 20 minutes at a time. Researchers will measure pain levels …

This study tests two different computer alerts designed to encourage doctors to refer heart patients to cardiac rehab. About 7,000 adults who had heart surgery or a stent in the past year will take part. The goal is to see if these simple reminders increase the number of people w…

This study tests whether using a CT scan to plan a heart stent procedure (PCI) makes it faster, safer, and more effective than the usual approach. About 200 adults with coronary artery disease will either get CT-guided planning or standard care. Researchers will compare procedure…

This observational study will follow 3000 patients with severely calcified coronary arteries who undergo a procedure to open the blockages (PCI). Researchers will track outcomes like heart attacks and repeat procedures over time. The goal is to learn which techniques work best in…

This study aims to understand why some people's coronary artery disease gets worse quickly while others' stays stable. Researchers will compare medical history, lab results, and imaging from 52 patients—34 with rapidly progressive disease and 18 with non-rapidly progressive disea…
