Summary

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 works best in everyday medical practice, not just in controlled trials.
