Objectives: The objective of this study is to quantitatively analyze the acute effects of atmospheric pollutant sulfur dioxide (SO2) on acute myocardial infarction (AMI) death in residents of Jinan City. Methods: A descriptive analysis of data on daily weather, air pollutants, and residents' AMI death events was collected from 2011 to 2017 in Jinan city. A generalized additive model (GAM) based on the Quasi-Poisson regression was used to analyze the associations of AMI deaths and SO2. The lag effect of current day (lag0~lag3) and cumulative lagged effect (lag01~lag03) were explored. The excess risk (ER) and 95% confidence interval (CI) of AMI deaths were calculated for every 10 μg/m3 increase in SO2. Results: A total of 40,843 AMI deaths occurred between 2011 and 2017, with a daily average of 16 deaths. During the same period, the average annual value of SO2was 65 μg/m3. An increase in SO2concentration of 10 μg/m3 was associated with an increased risk of death related to AMI at lag 1 by 0.35% (95% CI: 0.06%–0.64%). Especially in cold months, a higher increased risk of 0.49% (95% CI: 0.19%–0.79 %) for AMI death was observed with SO2a 10 μg/m3 increase. While there was a significant cumulative hysteresis effect, the maximum cumulative hysteresis effect appeared in lag 02. Conclusions: The atmospheric pollutant SO2in Jinan City has a significant acute effect on the risk of death from AMI , especially a higher increased risk was observed in cold months.
