The surveillance data of new cases of acute myocardial infarction (AMI) from January 1, 2013, to December 31, 2021, in Tengzhou City, Shandong Province, were used to analyze the incidence rate of AMI and its change trend among residents. The age and gender standardized incidence rate was calculated based on the 7th National Population Census 2020. The Cochran-Armitage trend test was used to analyze the trend of onset time and age. From 2013 to 2021, the crude and standardized incidence rate of total AMI in Tengzhou City declined from 130.07/100 000 and 161.12/100 000 to 76.15/100 000 and 72.77/100 000 (Z=-13.785 and -20.822, both P<0.001). The crude and standardized incidence rates of males were higher than those of females. In 2016, males aged 45-54 years old and females aged 35-64 years old increased by 33.33%, 103.65%, 106.30%, and 95.75% compared to 2015, and the differences were statistically significant (χ2=6.512, 4.965, 25.115, and 46.004, all P<0.05). The incidence rate of AMI in men aged<35 and 35-44 years old had an upward trend. From 2013 to 2021, the incidence rate of AMI decreased by 55.15% in urban areas and 36.59% in rural areas (Z=-8.529 and -11.235, both P<0.001).
采用山东省滕州市2013年1月1日至2021年12月31日急性心肌梗死（AMI）新发病例监测数据，分析居民AMI发病率及其变化趋势。以2020年全国第7次人口普查数据计算年龄和性别标化发病率。采用Cochran-Armitage趋势检验分析发病时间趋势和年龄趋势。2013—2021年滕州市总体AMI粗和标化发病率由130.07/10万和161.12/10万降低至76.15/10万和72.77/10万（Z=-13.785和-20.822，均P<0.001）；男性粗发病率和标化发病率高于女性。2016年男性45~54岁1个年龄段、女性35~64岁3个年龄段比2015年升高，差异均具有统计有意义［分别增高33.33%、103.65%、106.30%和95.75%（χ2值分别为6.512、4.965、25.115和46.004，均P值<0.05）］。<35岁和35~44岁年龄段男性的AMI发病率有升高的趋势。2013—2021年城区AMI发病率下降了55.15%、农村下降了36.59%（Z值分别为-8.529和-11.235，均P<0.001）。.
