: 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 .
Hyperuricemia and incident atrial fibrillation in a normotensive elderly population in Taiwan.
BACKGROUND AND AIM Atrial fibrillation ( AF ) is an important cardiovascular disease in the elderly . The association between hyperuricemia and AF is unclear . Therefore , we aim ed to investigate the prospect i ve relationship between uric acid and development of AF in a nationally representative cohort of elderly people . METHODS AND RESULTS A total of 1485 elderly people ( age ≥ 65 yrs ) from the Elderly Nutrition and Health Survey in Taiwan ( 1999 - 2000 ) were without AF on " electrocardiography " at baseline .  Incident AF events ( International Classification of Diseases , Ninth Revision , Clinical Modification , ICD-9-CM : 427.31 ) were identified using data from the National Health Insurance Data set . Hyperuricemia was defined as levels of uric acid > 7.0 mg/dL in men and 6.0 mg/dL in women . A Cox proportional hazards model was used to evaluate the association between hyperuricemia and incident AF . The follow-up period was from 1999 to 2000 to 2008 . During the follow-up period ( median : 9.16 yrs ) , 90 AF events occurred ( 44 in men and 46 in women ) . Older age , elevated systolic blood pressure , being an ex-smoker , and high uric acid were positively associated with incident AF . Hyperuricemia was positively associated with incident AF in normotensive ( age-adjusted hazard ratio ( HR ) : 2.65 and 95 % confidence intervals : 1.05 - 6.69 ) , but not in ( 1.20:0.74 - 1.94 ) hypertensive individuals ( systolic blood pressure ≥130 or diastolic blood pressure ≥85 or using hypertensive medicine ) . A significant association between hyperuricemia and AF ( 3.78 ; 1.24 - 11.59 ) remained after adjusting for other potential confounders among normotensive older persons . CONCLUSION Hyperuricemia is associated with the development of AF in elderly people with normal blood pressure
