Abstract
- Atrial fibrillation (AF) is the most common type of treated heart arrhythmia contributing to adverse cardiovascular events. The association between short-term air pollution exposure and AF episodes has been recognized. But the evidence of the association between long-term air pollution exposure and AF was limited, especially in developing countries. We performed a nationwide cross-sectional study among 1,374,423 individuals aged ≥35 years from 13 health check-up centers. Using logistic regression models, we assessed the association between long-term exposure to single air pollution and AF prevalence, including particulate matter (PM 2.5 and PM 10), ozone (O 3) and PM 2.5 compositions, which were estimated by high-resolution and high-quality spatiotemporal datasets of ground-level air pollutants for China. The quantile g-computation model was used to explore the joint effect of all exposures to air pollution and the contribution of an individual component to the mixture. In single-pollutant models, an increase of 10 μg/m3 in PM 2.5 (OR 1.031[95%CI 1.010,1.053]) and PM 10 (OR = 1.021 [95%CI 1.009,1.033]) was positively associated with AF prevalence. The stratified analyses revealed that these associations were significantly stronger in females, people <65 years old, and those with hypertension and diabetes. In the further exploration of the joint effect of PM 2.5 compositions (OR 1.060 [95%CI 1.022,1.101]) per quintile increase in all five PM 2.5 components), we found that PM 2.5 sulfate contributed the most. These findings provide important evidence for the positive relationship between long-term exposure to air pollution and AF prevalence in China and identify sulfate particles of PM 2.5 as having the highest contribution to the overall mixture effects among all PM2.5 chemical constituents. • Long-term exposure to PM 2.5 and PM 10 was associated with an increased risk for AF prevalence. • The risk of AF prevalence was higher with PM5 exposure than with PM10. • The associations were stronger in females, people <65 years old, and those with hypertension and diabetes. • PM2.5 sulfate contributed the most to the overall mixture effects among PM2.5 constituents.
