Could some heart patients safely stop blood thinners after ablation?
NCT ID NCT07496281
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether people with atrial fibrillation who have had a successful heart ablation and also have a heart stent can safely stop taking blood thinners. Participants who maintain a normal heart rhythm for at least a year after ablation will either continue blood thinners or switch to a single antiplatelet drug. The goal is to see if stopping blood thinners is as safe and effective as continuing them.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Non-vitamin K antagonist oral anticoagulant (NOAC) and single antiplatelet therapy (SAPT)
- What this could lead to
- If successful, this could show that some patients with atrial fibrillation and prior stents can safely stop blood thinners after successful ablation, reducing bleeding risk.
- What could go wrong
- This is a very small, early-phase trial with only 2 participants, so results may not apply broadly. Stopping blood thinners could increase the risk of stroke or heart attack.
