This study is tracking 1,000 adults who receive a special drug-coated stent called DESyne X2 to treat narrowed or blocked heart arteries. Researchers want to see how well the stent works in everyday medical practice and how safe it is. Participants will be followed for events lik…

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 a new type of heart stent (XIENCE Skypoint) with other stents used to treat blocked arteries. About 2000 adults with coronary artery disease will receive the new stent and be followed for a year. Researchers will track rates of death, heart attack, and the nee…

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 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 observes 10,000 people with a severe blockage in the left main coronary artery, a key heart vessel. It compares the long-term results of three approaches: medication alone, stenting with drug-coated stents, and bypass surgery. The goal is to see which works best in rea…

This study follows about 20,000 people with coronary artery disease who had a heart procedure guided by 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 attacks or repeat procedures…

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 track their long-term health, including survival, repeat heart attacks, and need for additional procedures.…

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…

This study is a large registry that will follow 25,000 people with multivessel coronary artery disease (blockages in multiple heart arteries) to see how they fare over the long term with different treatments: medication, bypass surgery, or stents. The goal is to understand which …
