Oral Anticoagulant Use in Atrial Fibrillation-Associated Ischemic Stroke: A Retrospective, Multicenter Survey in Northwestern China

Anticoagulation therapy has been recommended by major guidelines to reduce the risk of recurrent stroke in patients with atrial fibrillation-associated ischemic stroke (AFAIS). However, in real-world clinical practice, oral anticoagulants with either vitamin K antagonists or nonvitamin K antagonists are often underused for these patients. Here, we sought to investigate the current status of oral anticoagulant use in patients with AFAIS in northwestern China.
