Is anticoagulant therapy unnecessary for lower-risk Japanese patients with nonvalvular atrial fibrillation?
This editorial highlights the significant underuse of oral anticoagulation in Japanese patients with NVAF prior to stroke, emphasizing the need for appropriate stroke prevention even in lower-risk groups.
The percentof patients who took oral anticoagulant drugs to the index stroke/TIA was only 36.8%, even among the high-CHADS2 score patients. Although the main reason for the absence of anticoagulation therapy was lack of identification of NVAF prior to the index stroke/TIA, 30% of the patients in any of the low-, intermediate-, and high-risk groups were not taking anticoagulant drugs, even though NVAF had been detected.
