Thromboembolic Prevention in Atrial High-Rate Episodes: Is There Benefit? (NOAH-AFNET 6 Study) – American College of Cardiology
Prolonged atrial arrhythmias expose patients to increased risks of thromboembolism. The results of a meta-analyses revealed a fourfold increased risk of stroke and systemic embolism in patients with atrial high-rate episodes (AHRE) lasting ≥30 sec. 1 Nevertheless, these episodes are often subclinical and detected only on long-term implantable monitors. Whether initiating anticoagulation th erapy in this patient population can improve clinical outcomes is unknown. Two randomized controlled trials—the LOOP
