This study is watching 1,000 adults who get a DESyne X2 stent to open blocked heart arteries. Researchers track deaths, heart attacks, and repeat procedures for up to a year. The goal is to see how safe and effective the stent is in routine hospital care.

This study is testing a new type of heart stent, called XIENCE Skypoint, against other stents used to open blocked arteries. About 2,000 adults with coronary artery disease will receive the new stent and be followed for a year to see if it prevents death, heart attacks, or the ne…

This study looks at how well a drug-coated balloon works over time for people with coronary artery disease. Researchers will track 1,500 patients to see if the balloon helps prevent heart attacks, death, or the need for repeat procedures. The goal is to understand the treatment's…

This study compares two techniques used during heart stent placement for left main coronary artery disease: one guided by standard angiography and another using a pressure wire (FFR). About 960 adults with significant left main artery blockage will be enrolled. The goal is to see…

This study is following 50,000 people with coronary artery disease who receive drug-eluting stents during routine care. The goal is to see how well these stents work and how safe they are in everyday practice. Researchers will track major heart problems like death, heart attack, …

This study will follow about 20,000 people with coronary artery disease who had a procedure to open blocked heart arteries using a special measurement called FFR. The goal is to see how well the treated arteries hold up over 2 years by tracking heart-related events like heart att…

This study follows 25,000 adults with multivessel coronary artery disease to see how different treatments—medication, bypass surgery, or stents—affect their long-term health. Researchers track major events like death, heart attack, stroke, and repeat procedures. The goal is to un…

This study is observing 10,000 people with a severe blockage in the left main coronary artery to see how different treatments—medication, stents, or bypass surgery—work in everyday medical practice. Researchers will track deaths, heart attacks, and other major events over the lon…

This study is a registry that will follow 5,000 people who had a heart attack (acute myocardial infarction) and were treated at Asan Medical Center in Korea. The goal is to see how they do over the long term, including whether they survive, have another heart attack, or need addi…

This study is observing how well a procedure called rotational atherectomy works in everyday medical practice for people with hardened or narrowed heart arteries. Researchers will follow 500 patients for one year to see if the procedure is safe and effective. The goal is to gathe…

This study follows 4,000 people with coronary artery disease who have had special imaging of their heart arteries. Researchers want to see if the images can predict serious heart events like heart attack or death. No new treatment is given; the goal is to learn how well imaging c…
