This study looks at how well different drug-eluting stents work in real-world patients with coronary artery disease. Researchers are comparing newer stents to older ones to see which are safest and most effective. The study includes up to 50,000 people who need a stent to open bl…

This study is testing a new heart stent called Coroflex ISAR NEO in 1,000 people with narrowed heart arteries. The goal is to see how safe and effective it is compared to other stents in everyday medical practice. Researchers will track major heart problems like death, heart atta…

This study is tracking 1,000 people who receive the DESyne X2 drug-eluting stent to treat narrowed or blocked coronary arteries. Researchers are monitoring how often patients experience serious heart events like death, heart attack, or the need for another procedure. The goal is …

This study compares two methods of guiding stent placement in the left main coronary artery: standard angiography versus fractional flow reserve (FFR), which measures blood pressure across the blockage. About 960 adults with significant left main artery disease will be randomly a…

This study follows 840 people with a completely blocked coronary artery (chronic total occlusion) for at least 10 years. Half received a drug-eluting stent, and half got optimal medical therapy alone. Researchers will compare rates of death, heart attack, stroke, and repeat proce…

This study is tracking 50,000 people with coronary artery disease who receive drug-eluting stents during a routine procedure to open blocked heart arteries. Researchers want to see how well these stents prevent major heart problems like death, heart attack, or the need for anothe…

This study compares a new type of heart stent (XIENCE Skypoint) with other drug-coated stents in 2000 people with coronary artery disease. The goal is to see which stent is more effective and safer in real-world use. Participants will be followed for at least one year to track ou…

This study is tracking 1,500 people with coronary artery disease who are treated with a drug-eluting balloon during angioplasty. The balloon releases a medicine (paclitaxel) to help keep the artery open. Researchers are checking how well it works and if it is safe over the long t…

This study follows about 20,000 people with coronary artery disease who had a special test called FFR to guide their artery-opening procedure. Researchers want to see how these patients' heart health changes over 2 years. The goal is to better understand the long-term results of …

This study is observing 10,000 people with severe narrowing in the left main coronary artery, a critical heart vessel. Researchers are comparing the long-term results of three approaches: medication, stenting with drug-coated stents, and bypass surgery. The goal is to see which w…

This study follows 4000 people with coronary artery disease who have had special imaging of their heart arteries. Researchers will track them for 5 years to see how well the images predict serious events like heart attacks or the need for repeat procedures. The goal is to improve…

This registry is following 5,000 people who had a heart attack and were treated with medications, stents, or bypass surgery at Asan Medical Center in Korea. Researchers are tracking deaths, repeat heart attacks, and other major events over the long term to understand which treatm…

This study follows 25,000 people with multivessel coronary artery disease to see how different treatments—medication, surgery, or stents—affect long-term health. Researchers will track serious events like heart attacks, strokes, and death. The goal is to learn which approach work…

This study is tracking 500 patients who received rotational atherectomy, a procedure that uses a tiny rotating burr to grind away hardened plaque in heart arteries. Researchers want to see how safe and effective it is in real-world settings. The main goal is to measure how many p…
