Summary

Atrial fibrillation is a clinically significant cardiac arrhythmia that increases the risk of stroke by 3 to 4 times. Oral anticoagulation has been shown to mitigate stroke risk by two-thirds among patients with AF and is widely recommended in optimizing AF management.Direct oral anticoagulants have also been demonstrated to be superior to warfarin with respect to the risk of fatal bleeding and stroke prevention. However, the previous study finding highlighted a great gap between current guidelines and the clinical management of AF .Nonetheless, the decision for anticoagulant use is not straightforward.It is worth to investigate the updated prevalence of anticoagulant use, the reasons for not receiving anticoagulant, and the factors independently associated with anticoagulant refusal in patients with non-valvular atrial fibrillation.
