To explore the variation for mortality/incidence (MI) ratio on acute myocardial infarction (AMI) in Tianjin from 2007 to 2015. Data from both disease and death surveillance systems on AMI in Tianjin from 2007 to 2015, were collected. Incidence and mortality for AMI of people over 35 years old were calculated and fitted by using the exponential model. Annual MI ratios by gender and different age groups were calculated. Join-point regression was used for sensitivity analysis of the ratio. Other than 2007, 2010, 2014 and 2015, the ratios in rest of the years were all bigger than one. From 2007 to 2015, the ratios were ranging from 0.80 to 1.60, with 0.90 to 1.80 for females, and 0.80 to 1.40 for males, respectively. The MI ratio on AMI changed relatively stable in Tianjin from 2007 to 2015, but the AMI incidence data in Tianjin seemed underreported, especially for people over 75 years old, indicating that some elderly AMI cases were not reported to the disease surveillance system.
探讨2007年至2015年天津市急性心肌梗死（AMI）死亡率/发病率（MI）比值的变化情况。收集了天津市2007年至2015年疾病监测系统和死亡监测系统中关于AMI的数据。计算并采用指数模型拟合了35岁以上人群的AMI发病率和死亡率。计算了按性别和不同年龄组划分的年度MI比值。采用连接点回归对该比值进行敏感性分析。除2007年、2010年、2014年和2015年外，其余年份的比值均大于1。2007年至2015年，该比值范围为0.80至1.60，女性为0.90至1.80，男性为0.80至1.40。2007年至2015年天津市AMI的MI比值变化相对稳定，但天津市的AMI发病率数据似乎存在漏报情况，尤其是75岁以上人群，这表明一些老年AMI病例未向疾病监测系统报告。
