Blood thinner safety under the microscope: 2,000 heart patients enrolled
NCT ID NCT04347200
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This registry is following 2,000 people with chronic coronary artery disease who are taking long-term blood thinners (antiplatelet or anticoagulant drugs). The goal is to track how often serious bleeding or clotting events (like heart attacks or strokes) occur. By understanding these risks, doctors may be able to tailor treatment more safely for each patient.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Antiplatelet or anticoagulant drugs (blood thinners)
- What this could lead to
- If successful, this could help doctors better balance the risks of bleeding and clotting when prescribing long-term blood thinners for heart disease patients.
- What could go wrong
- This is an observational registry, not a treatment trial, so it won't test a new drug or cure. Results may not apply to all patients or lead to immediate changes in care.
