Background:The association between serum uric acid (UA) levels and atrial fibrillation (AF) in the general population in Japan is not well known.

Methods and Results:In total, 285,882 consecutive subjects (men, 130,897; women, 154,985; age, 58±15 years) not receiving treatment for hyperuricemia who underwent health checkups were enrolled. Subjects were stratified into deciles according to age, body mass index, estimated glomerular filtration rate, systolic blood pressure, and UA level. AF prevalence was calculated for each decile. The odds ratio that defined the decile with the lowest AF prevalence as reference was calculated in each sex. In men, the mean UA was 6.0±1.4 mg/dl; AF prevalence was 1.8% and was lowest in the decile with UA 4.4–4.9 mg/dl. Deciles with both high and low UA (5.4–5.6 mg/dl to >7.8 mg/dl and <4.3 mg/dl) were associated with significantly higher AF prevalence. In women, the mean UA was 4.5±1.1 mg/dl; AF prevalence was 0.7% and was lowest in the decile with UA 3.6–3.8 mg/dl. Deciles with highest UA (5.0–5.2 mg/dl to >5.9 mg/dl) were associated with significantly higher AF prevalence. The analysis adjusted for other clinical covariates demonstrated an independent association between UA and AF in both sexes.

Conclusions:In a representative Japanese general population, UA level was significantly associated with AF, independently of other cardiovascular risk factors.
