2015—2020年成都市缺血性心脏病死亡率及变化趋势分析

Trend of mortality of ischemic heart diseases from 2015 to 2020 in Chengdu

目的 了解成都市缺血性心脏病死亡情况及变化趋势。方法 收集全国疾病监测系统2015—2020年成都市缺血性心脏病数据,计算粗死亡率和标化死亡率,率的比较采用χ^(2)检验,采用年度变化百分比(APC)评价不同组别率的变化趋势,并对其进行t检验,以P<0.05为差异有统计学意义。结果 2015—2020年成都市缺血性心脏病粗死亡率为60.35/10万,呈逐年上升趋势(APC=6.29%,P<0.001),标化后年均死亡率为66.75/10万,男性逐年死亡率均高于女性(P均<0.05)。死亡率随年龄增加而上升,50~59岁人群粗死亡率年均增速最快(APC=7.79%,P<0.001)。亚型中以急性心肌梗死占比最大,超50%。结论 2015—2020年成都市缺血性心脏病死亡率呈上升趋势,应加强重点亚型和重点人群的防控。

Objective To investigate the mortality and its trend of ischemic heart diseases in Chengdu.Methods Data of ischemic heart diseases from 2015 to 2020 in Chengdu were collected from the National Disease surveillance system. Crude and standardized mortality rates were calculated and compared by using chi-square tests. The annual percentage change(APC) was used to evaluate the changing trend of the rates in different groups, and t-test was performed. P<0.05 was considered as statistically significant. Results The crude mortality of ischemic heart disease in Chengdu was60.35/105, showing an increasing trend(APC=6.29%, P<0.001). After standardization, the average annual mortality rate was 66.75/105, and the standardized mortality in males was higher than that in females(P<0.05). The crude mortality increased with age;specifically, the crude mortality rate of 50-59 year increased the fastest(APC=7.79%, P<0.001). Acute myocardial infarction accounted for more than 50% of deaths in all subtypes. Conclusions The mortality of ischemic heart diseases was on the rise in Chengdu from 2015 to 2020, and the prevention and control of key subtypes and populations should be strengthened.
