DNA-Guided heart drug choice may save lives in coronary artery disease
NCT ID NCT06665919
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether using a person's genetic information to choose their blood-thinning medication (clopidogrel or an alternative) leads to better outcomes after a heart procedure. 283 adults with chronic coronary artery disease who had a stent placed were split into two groups: one received standard care, and the other had their treatment guided by a genetic test. The goal was to see if the genetic approach reduced deaths, heart attacks, and other heart-related events in real-world practice.
