Suboptimal Anticoagulant Management in Japanese Patients with Nonvalvular Atrial Fibrillation Receiving Warfarin for Stroke Prevention

In this EMR-based clinical study, patients who switched to DOACs had both poor or inadequate PT-INR control and higher risk factors of stroke. Many patients receiving warfarin did not achieve sufficient PT-INR therapeutic range. DOACs could be recommended in Japanese patients with NVAF with inadequate PT-INR control and increased risk of stroke.
