An anticoagulation therapy is a critical treatment to prevent thromboembolism in non-valvular AF (NVAF) patients. Warfarin, a vitamin K antagonist, is the first oral anticoagulant approved for the treatment for prevention of thromboembolism and it had long been the only oral anticoagulant until the first non-vitamin K antagonist oral anticoagulants (NOACs). However, its safety and effectiveness remains unknown in real-world clinical practice in Japan. This study will evaluate the risk of stroke/SE as well as the risk of bleeding in the real world settings in Japan in patients with NVAF who initiated any of OACs (apixaban, dabigatran, edoxaban, rivaroxaban, or warfarin)
