Stopping oral anticoagulation therapy after successful atrial fibrillation ablation may lower risk of harm

Discontinuing oral anticoagulation (OAC) therapy resulted in a lower risk of a composite of stroke, systemic embolism or major bleeding than continuing OAC therapy in patients who had successful ablation for atrial fibrillation at least 12 months previously, according to results from a late-breaking trial. Atrial fibrillation (AF) is a common type of arrhythmia characterized by an abnormal irregular heartbeat that can increase the risk of stroke and thromboembolism (blood clots). Ablation can be used to destroy small sections of heart tissue that may be causing abnormal heartbeats. Oral anticoagulation (OAC) is recommended in all patients for at least two...
