New hope for stroke prevention: heart device may be safer than blood thinners after brain bleed

NCT ID NCT04298723

First seen Nov 01, 2025 · Last updated May 13, 2026 · Updated 23 times

Summary

This study tests if closing off a small pouch in the heart (the left atrial appendage) with a device is better than taking blood thinners for people with an irregular heartbeat (atrial fibrillation) who have already had a brain bleed. Both approaches aim to prevent strokes, but blood thinners can increase bleeding risk. The device may offer a safer long-term solution. About 530 adults will be randomly assigned to one of the two treatments and followed for several years.
