- Abstract: Atrial fibrillation (AF) is associated with an increased incidence of ischemic stroke and transient ischemic attack. A confluence of various factors such as blood stasis, endothelial dysfunction, and prothrombotic state could be contributing to the thrombogenesis in AF. Anticoagulation is the first-line therapy for the prevention of thromboembolism by AF. In current days, non-vitamin K dependent oral anticoagulants (NOAC) are considered as the preferred choice of anticoagulants to prevent ischemic stroke in patients with AF. NOACs have comparable good efficacy and better safety with a predictable anticoagulant effect without the routine coagulation monitoring compared to vitamin K dependent oral anticoagulant. However, the proper use of NOACs needs a careful approach to many practical aspects for balancing the preventing thromboembolic events and bleeding risk. Thus, understanding the drug metabolism and indication of NOAC for a specific situation is essential. In this article, we review major clinical trials, the mechanism, and the use of NOACs in the actual clinical setting of managing ischemic stroke patients.
