Aspirin after brain bleed: could a common pill prevent another disaster?
NCT ID NCT07243704
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether taking a daily low-dose aspirin can reduce the risk of major heart problems and strokes in people who have survived a brain bleed (intracerebral hemorrhage). About 5,676 adults will be randomly assigned to receive either aspirin or a placebo for up to three years. The goal is to see if the benefits of preventing clots outweigh the risk of causing another bleed.
