5,000 heart attack patients tracked for years to see what treatments work best

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 treatments lead to the best outcomes. The study does not test a new drug or device—it observes real-world results to improve future care.
