This paper explored whether air pollutants influenced acute aortic dissection (AAD) incidence in a moderately polluted area. A total of 494 AAD patients’ data from 2013 to 2016 were analyzed. The results showed that AAD had the strongest associations with P M 10 , S O 2 , N O 2 , C O , and O 3 on the day before an AAD incident (lag1) and with P M 2.5 two days before an incident (lag2) in single-pollutant model. In the three-pollutant model, P M 10 was associated with the highest risk of adverse effects (RR = 1.37, 95% CI: 1.22, 1.53), whereas P M 2.5 was associated with the lowest risk (RR = .83, 95% CI: .79, .88). Both P M 2.5 and P M 10 were affected by season, and S O 2 was significantly different between heating and non-heating seasons as well. This study revealed significant associations between short-term P M 2.5 , P M 10 , and S O 2 exposure and daily AAD incidence, showing that P M 10 and S O 2 were strong predictors of AAD incidence in a moderately polluted area.
