NCT ID NCT01341327
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
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.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this study could help doctors choose the best treatment for left main coronary artery disease based on real-world evidence.
What could go wrong
This is an observational study, not a controlled trial, so results may be influenced by factors like patient choice or doctor preference. It does not test a new treatment.
