Figure 1. Decision-making process of stroke prevention in patients with AF from Asia. The decision-making process includes stroke risk evaluation, OAC choosing and bleeding risk control. Stroke and bleeding risk re-evaluation should be made at each medical contact.AF = atrial fibrillation; CHA2DS2-VASc = congestive HF, hypertension, age ≥75 (2 points), diabetes mellitus, previous stroke/TIA (2 points), vascular disease, age 65–74, sex category (female gender); HAS-BLED = hypertension, abnormal renal/liver function, stroke, bleeding history or predisposition, labile international normalized ratio, elderly, drugs/alcohol concomitantly; NOAC = non-vitamin K antagonist oral anticoagulant; OAC = oral anticoagulation; TTR = time in therapeutic range; VKA = vitamin K antagonist. *Including patients' preference, risk factor severity (such as blood pressure control), bleeding risk.
