HALTI trial: could stopping blood thinners after heart repair be safer?
NCT ID NCT04475510
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether people aged 60 or younger who had a stroke caused by a hole in the heart (PFO) can safely stop taking blood thinners one year after the hole is closed. The goal is to see if stopping these drugs reduces the risk of bleeding without increasing the chance of another stroke. About 100 participants will be followed with brain scans to check for new strokes or silent brain injuries.
