: 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 .
Gender-specific relationship between serum uric acid level and atrial fibrillation prevalence.
BACKGROUND Although various kinds of cardiovascular risk factors have been reported to be associated with  atrial fibrillation ( AF )  , the relationship between serum uric acid level and AF has not been fully examined . METHODS AND RESULTS Data were collected from a single hospital-based cohort in the Shinken Data base 2004 - 2008 ( n=11,123 ) , and consisted of serum uric acid level for 7,155 patients . The association between serum uric acid level and AF prevalence was evaluated on logistic regression . Uric acid significantly increased the crude AF prevalence in both men and women ( both , P<0.001 ) . The odds ratio ( OR ) and 95 % confidence interval ( 95%CI ) in the highest tertile compared with the lowest one were 3.368 ( 2.478 - 4.578 ) and 1.408 ( 1.169 - 1.695 ) in women and men , respectively . Uric acid was also significantly associated with other various cardiovascular risk factors for AF . Even after the multivariate model was adjusted using these variables , the effect of uric acid on AF was independent in women ( OR , 1.888 ; 95%CI : 1.278 - 2.790 ) , but not in men . CONCLUSIONS Reflecting the composite of various cardiovascular risk factors , serum uric acid level was apparently associated with AF prevalence . The independent association in women might imply some sex-specific mechanisms . The results should be confirmed in prospect i ve studies
