NCT ID NCT06953726
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study will compare two widely used blood thinners, apixaban (Eliquis) and rivaroxaban (Xarelto), in about 10,000 veterans with atrial fibrillation (an irregular heartbeat). The goal is to see which drug better prevents strokes and major bleeding. Participants must already be taking one of these medications, and all data will be collected from medical records over about 7 years.
