Examining the Relationships Between Air Pollutants and the Incidence of Acute Aortic Dissection with Electronic Medical Data in a Moderately Polluted Area of Northwest China

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 [Formula: see text] , [Formula: see text] , [Formula: see text] , [Formula: see text] , and [Formula: see text] on the day before an AAD incident (lag1) and with [Formula: see text] two days before an incident (lag2) in single-pollutant model. In the three-pollutant model, [Formula: see text] was associated with the highest risk of adverse effects (RR = 1.37, 95% CI: 1.22, 1.53), whereas [Formula: see text] was associated with the lowest risk (RR = .83, 95% CI: .79, .88). Both [Formula: see text] and [Formula: see text] were affected by season, and [Formula: see text] was significantly different between heating and non-heating seasons as well. This study revealed significant associations between short-term [Formula: see text] , [Formula: see text] , and [Formula: see text] exposure and daily AAD incidence, showing that [Formula: see text] and [Formula: see text] were strong predictors of AAD incidence in a moderately polluted area.
