Active FXI Can Independently Predict Ischemic Stroke in Anticoagulated Atrial Fibrillation Patients: A Cohort Study

Abstract

FXIa present in circulating blood is associated with increased risk of ischemic stroke and cardiovascular death in anticoagulated AF patients during long-term follow-up. FXIa inhibition could be useful in cardiovascular prevention in AF beyond the current oral anticoagulation.
