: 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 .
Secular Trends, Treatments, and Outcomes of Middle Eastern Arab and South Asian Patients Hospitalized With Atrial Fibrillation
A prospect i ve registry was made of all patients hospitalized with atrial fibrillation ( AF ) in the State of Qatar from 1991 to 2010 .  Clinical characteristics , management , and outcomes were compared according to ethnicity ( Middle Eastern Arab vs South Asian ) . During this 20-year period , 2857 Arabs and 548 Asians were hospitalized for AF . Arabs were 9 years older and more likely to have hypertension , diabetes mellitus ( DM ) , chronic renal impairment , and dyslipidemia than the Asians . Valvular heart disease and acute coronary syndromes were more common among Asians , while congestive heart failure was more common in Arabs . The overall inhospital mortality was lower in Asians than that of Arabs , while stroke rates were comparable . There was an increase in the prevalence of DM and hypertension in both the groups in the latter years of the study period , but there was no change in mortality trends . Our findings underscore the need to study AF according to ethnicity
