Heart monitor could make blood thinners safer for heart attack patients

NCT ID NCT04276155

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests whether an implantable heart monitor with remote follow-up can help doctors decide when to prescribe blood thinners to patients who have had a heart attack and developed new atrial fibrillation. The goal is to reduce bleeding complications compared to the standard approach of giving blood thinners based on a risk score. About 500 participants will be randomly assigned to either standard care or the implantable monitor strategy.

Active substance

implantable heart monitor with remote follow-up

What this could lead to

If successful, this could lead to a safer way to decide when to use blood thinners in heart attack patients with atrial fibrillation, reducing bleeding risks.

What could go wrong

This is a Phase 4 study, so the approach is already in use, but it may not prove safer than standard care. The implant device itself carries small risks like infection or malfunction.
