The unmet need of stroke prevention in atrial fibrillation in the far East and South East Asia.
The prevalence of atrial fibrillation (AF) is high in both community- and hospital-based studies in the Far East and South East Asia. Hypertension is the most common risk factor, but coronary heart disease and diabetes mellitus are other important co-morbidities in these countries. Anticoagulant therapy use was low, being 0.5%-28% in Malaysia, Singapore, and China. The reported rate of stroke related to AF was 13.0%-15.4% based on community studies in those countries, and was 3.1%-24.2% of stroke rate in hospital-based cohorts. Better assessment of thromboembolic and bleeding risks is important. International guidelines now recommend the use of the CHA2DS2-VASc score to identify the ''truly low-risk'' AF patients, who do not need antithrombotic therapy, whilst those with ≥ 1 stroke risk factors can be offered oral anticoagulation. Aspirin is ineffective and may not be any safer than oral anticoagulants, especially in the elderly. It is anticipated that the availability of the new oral anticoagulant drugs would improve our efforts for stroke prevention in the Far East and South East Asia, especially where anticoagulation monitoring for warfarin is suboptimal.
