About the Article
We investigated seasonal variation of acute exacerbation of atrial fibrillation (AAF) and contributing environmental factors.
AAF events, meteorological elements, and air pollutants in Seoul between 2013 and 2015 were obtained from the nationwide database. AAF was defined if a patient visited the emergency room due to any AF-relevant symptoms or signs.
AAF occurred less frequently in summer than in other seasons (6.71 vs 7.25 events/d, P = 0.005). AAF tended to decrease with an increase of air temperature ( r = –0.058). Among air pollutants, NO 2 was significantly lower in summer and positively correlated with AAF after adjusting for other variables ( β = 3.197).
The rate of AAF events was the lowest in summer; air temperature and NO 2 were contributing factors. The weather and environmental conditions should be considered as risk factors of AAF.
