Read our Coronary Artery Disease research guide →This is a large registry study — a database that collects real-world information — designed to compare three ways doctors treat a serious blockage in the left main coronary artery (a major blood vessel supplying your heart). Researchers will follow approximately 5,000 patients across Korea and the Asia-Pacific region to see how well each treatment option works, whether that's medication alone, a catheter-based procedure with a stent, or open-heart surgery.
Left main coronary artery disease is a serious condition, and doctors aren't always certain which treatment approach is best for each patient. This study aims to gather real-world evidence comparing the long-term outcomes of different treatments to help doctors make better decisions.

As a participant, you would allow researchers to collect and track your medical information and health outcomes over time. You would not receive a new medication or procedure as part of joining the study; rather, your doctors would treat your condition as they normally would, and the study team would record how your chosen treatment works out. You'll need to attend scheduled follow-up visits as agreed with your study site.
