: 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 .
Prevalence of atrial fibrillation in an urban population in India: the Nagpur pilot study
Objectives Atrial fibrillation ( AF ) is the most common sustained arrhythmia encountered in clinical practice with major public health impact mainly due to the increased risk of stroke . The recent Global Burden of Disease Study reported a lack of prevalence data from India . Our goal was to conduct a pilot study to evaluate the feasibility of assessing AF prevalence and stroke prophylaxis in an urban Indian community . Methods A screening camp was conducted in Nagpur , India , that evaluated adults aged ≥18 years . We collected  demographics , recorded blood pressure , height , weight and the 12-lead electrocardiogram ( ECG ) .  The presence of diabetes and hypertension was recorded by self-reported history . Patients diagnosed with AF were evaluated further to assess aetiology and management . Results Of the total 4077 r and omly selected , community-dwelling adults studied , 0.196 % ( eight patients ) were found to have AF . Mean age of the population was 43.9±14.8 , and 44.5 % were female . The mean age of the patients with AF was 60.5±15.8 years ( five females )  . Rheumatic heart disease was found in five patients with AF . Three patients had history of stroke ( 37.5 % ) and one had peripheral arterial thrombosis . Three patients were on warfarin , but without routine international normalised ratio ( INR ) monitoring . One patient was on aspirin . Five patients were on β-blockers and one on both β-blocker and digoxin . Conclusions The prevalence of AF was low compared with other regions of the world and stroke prophylaxis was underused . A larger study is needed to confirm these findings . This study demonstrates that larger evaluations would be feasible using the community-based techniques employed here
