OCEAN Trial Summary

This trial is comparing medical approaches for stroke prevention in people who have atrial fibrillation (AF) and have undergone a successful procedure called ablation to eliminate or substantially reduce the arrhythmia.

Who is the study for?
This trial is for adults over 18 who've had successful catheter ablation for non-valvular atrial fibrillation at least a year ago, with no arrhythmia since then and have a CHA2DS2-VASc score of 1+. It's not for those with severe kidney issues, recent strokes, conditions needing long-term blood thinners other than AF, or women at risk of pregnancy not using contraception.Check my eligibility
What is being tested?
The study compares two stroke prevention strategies in post-ablation AF patients: taking the oral anticoagulant Rivaroxaban versus daily Aspirin. The goal is to determine which approach is more effective after the elimination of arrhythmia through ablation.See study design
What are the potential side effects?
Possible side effects include bleeding risks associated with both Rivaroxaban and Aspirin. Rivaroxaban may also cause digestive tract discomfort, dizziness, or headaches. Aspirin can lead to stomach ulcers or increase the chance of bruising.
