In a Japanese general population, the prevalence of atrial fibrillation increased between 2008 and 2015, with hypertension and BMI identified as significant modifiable risk factors for new-onset atrial fibrillation.
May inform AF risk stratification in Japanese adults; leaves open whether modifying hypertension or BMI reduces incidence.
BACKGROUND: Although National Health Insurance special health checkups have been useful for the diagnosis of metabolic syndrome, they are insufficient to identify atrial fibrillation (AF). In Tama City in Tokyo, 12-lead electrocardiogram has been included as an essential examination in special health checkups to diagnose AF since 2008. METHODS AND RESULTS: increase; HR, 1.07; 95% CI: 1.00-1.12, P=0.049) were significant risk factors for new-onset AF in addition to age and male sex. CONCLUSIONS: Prevalence of AF increased between 2008 and 2015. Age, male sex, hypertension, and BMI were significant predictors for future incidence of AF in the general population without overt cardiac disease. Controlling hypertension and BMI may prevent new-onset AF in the general population.
