Heart stent patients: new study aims to find safer blood thinner combo
NCT ID NCT06821191
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two strategies to reduce bleeding risk in people who take two blood thinners after having a stent placed in their heart. The goal is to see if lowering the dose of one drug works as well as switching to a different drug. About 78 adults who have had a stent will participate.
