Blood clot patients on heart meds: safer combo found?
NCT ID NCT05627375
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks for the best way to treat people who have a blood clot (like in the leg or lung) and also take daily aspirin or similar drugs for heart disease. Both conditions need blood thinners, but taking them together raises the risk of dangerous bleeding. The trial will compare different treatment plans in 1,400 adults to find which one prevents new clots and heart problems while causing the least bleeding.
