Blood thinner after heart procedure: hope for artery health, but trial stopped short
NCT ID NCT03630055
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether taking the blood thinner rivaroxaban for 7 days after heart catheterization via the wrist could prevent the wrist artery from becoming blocked. About 930 adults were planned, but the trial was stopped early. The main goal was to see if the artery stayed open at 30 days, while also checking for major bleeding risks.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Rivaroxaban (Xarelto), a blood thinner
What this could lead to
If it worked, a short course of rivaroxaban could reduce the risk of radial artery blockage after heart catheterization, preserving the artery for future use.
What could go wrong
The trial was terminated early, so we don't have enough data to know if it works or is safe. Blood thinners like rivaroxaban also raise the risk of bleeding.
