: The incidence and prevalence of AF have increased in recent years , although great variability still exists in Asian countries .
Variability in annual IS risk in patients with AF was apparent between hospital‐ and community‐based studies .
BACKGROUND : Our previous review reported great variability in the incidence and prevalence of atrial fibrillation ( AF ) in non‐Western cohorts , especially from Asian countries ; in recent years , epidemiologic studies on AF have been increasingly reported from Asia .
METHODS : The goal of this up date d systematic review was to present the current knowledge base of AF epidemiology in Asian countries since our previous review .
Current Status and Time Trends of Oral Anticoagulation Use Among Chinese Patients With Nonvalvular Atrial Fibrillation: The Chinese Atrial Fibrillation Registry Study
Background and Purpose — Reported rates of oral anticoagulation ( OAC ) use have been low among Chinese patients with atrial fibrillation ( AF ) . With improved awareness , changing guidelines , this situation may be changing over time . We aim ed to explore the current status and time trends of OAC use in Beijing . Methods — We used the data set from the Chinese Atrial Fibrillation Registry ( CAFR ) , a prospect i ve , multicenter , hospital-based registry study involving 20 tertiary and 12 nontertiary hospitals in Beijing . A total of 11 496 patients with AF were enrolled from 2011 to 2014 . Results — Seven thous and nine hundred seventy-seven eligible patients were included in this ancillary study . The proportions of OAC use were 36.5 % ( 2268/6210 ) , 28.5 % ( 333/1168 ) , and 21.4 % ( 128/599 ) for patients with CHA2DS2-VASc scores ≥2 , 1 , and 0 , respectively . Persistent AF , history of stroke/transient ischemic attack/peripheral embolism , diabetes mellitus , higher body mass index , and tertiary hospital management were factors positively associated with OAC use , whereas older age , previous bleeding , hypercholesterolemia , and established coronary artery disease were factors negatively associated with OAC use . Among patients with CHADS2 scores ≥2 and CHA2DS2-VASc scores ≥2 , the proportion of OAC use increased from 31.3 % to 64.5 % and 30.2 % to 57.7 % , respectively , from 2011 to 2014 . Variation in OAC  use was substantial among different hospitals . Conclusions — An improvement of OAC use among Chinese patients with AF in Beijing is observed in recent years although only 36.5 % of patients with CHA2DS2-VASc score ≥2 received OAC . However , variations between different hospitals were large , suggesting that better education and awareness are needed to improve efforts for stroke prevention among AF patients .
