First seen Jan 25, 2026 · Last updated May 01, 2026 · Updated 17 times

Summary

This study tests whether a simple blood test can help doctors safely lower the dose of strong blood thinners in people who have had a heart attack or unstable chest pain. The goal is to reduce dangerous bleeding without increasing the risk of new clots or heart problems. About 634 adults who recently had a stent placed and are on two blood thinners will be followed to see if this personalized approach works better than standard care.
