Ischemic Stroke despite Oral Anticoagulant Therapy in Patients with Atrial Fibrillation

Abstract

Patients with AF who have an ischemic stroke despite previous oral anticoagulation are at a higher risk for recurrent ischemic stroke despite a CHA₂ DS₂ -Vasc score similar to those without prior oral anticoagulation. Better prevention strategies are needed for this high-risk patient group. ANN NEUROL 2020.
