目的 分析万州区2018年居民急性心肌梗死死亡水平和疾病负担。方法 根据2018年万州区居民死因监测数据,分析因急性心肌梗死导致居民粗死亡率、标化死亡率、年龄别死亡率、构成比、期望寿命、早死概率、去死因期望寿命、期望寿命损失年数、早逝导致的寿命损失年、YLL率、平均减寿年。结果 2018年万州区居民急性心肌梗死粗死亡率50.98/10万,标化死亡率36.07/10万。男性急性心肌梗死粗死亡率(50.23/10万)和标化死亡率(35.07/10万)均低于女性(51.72/10万和37.47/10万),差异无统计学意义(χ²=0.18,P=0.649;χ²=0.67,P=0.421)。小于50岁人群急性心肌梗死死亡率低于10.00/10万,50岁后随年龄的增长呈现上升的趋势(χ²=20183.86,P＜0.001)。2018年万州区心肌梗死早死概率为1.12%,男性心肌梗死早死概率(1.41%)与女性(0.84%)比较,差异有统计学意义(χ²=1198.748,P＜0.05)。2018年万州区心肌梗死导致的期望寿命损失年数(Years of life expectancy lost,YLEL)为0.69岁,寿命损失年(years of life lost,YLL)率为8.58年/千人,YLL率男性(9.77年/千人)高于女性(0.29年/千人)。平均潜在寿命损失年(average years of life loss,AYLL)为16.83人年,男性AYLL(19.45人年)高于女性(14.36人年)。结论 万州区居民急性心肌梗死死亡率与早死亡概率高,疾病负担重,应加强急性心肌梗死的综合防治。

Objective To analyze the death level and disease burden of acute myocardial infarction (AMI) of Wanzhou District in 2018. Methods According to the death cause monitoring data of residents in Wanzhou District in 2018,analyze the crude death rate,standardized death rate,age-specific death rate,composition ratio,life expectancy,premature death rate,life expectancy without cause of death,years of life expectancy lost (YLEL),years of life lost (YLLs) with premature death,YLL rate,and average years of life reduction caused by acute myocardial infarction. Results In 2018,the crude death rate of acute myocardial infarction in Wanzhou District was 50.98/100,000,and the standardized death rate was 36.07/100,000.The crude death rate (50.23 / 100,000) and standardized death rate (35.07 / 100,000) of acute myocardial infarction in men were lower than those in women (51.72 / 100000 and 37.47 / 100,000).There was no significant difference (χ²= 0.18,P= 0.649;χ²= 0.67,P= 0.421).The mortality of acute myocardial infarction was lower than 10.00/100,000 in people under 50 years old,and increased with the increase of age after 50 years old (χ²= 20183.86,P＜ 0.001).In 2018,the premature death rate of myocardial infarction in Wanzhou District was 1.12%.Compared with women (0.84%),the premature death rate of myocardial infarction in men was significantly different (χ²= 1198.748,P＜0.05).In 2018,the years of life expectancy lost (YLEL) caused by myocardial infarction in Wanzhou District was 0.69 years,the years of life lost (YLL) rate was 8.58 years / 1000,and the YLL rate of men (9.77 years / 1000) was higher than that of women (0.29 years / 1000).The average years of life loss (AYLL) was 16.83 person years,and the male AYLL (19.45 person years) was higher than the female (14.36 person years). Conclusion The mortality and premature mortality of acute myocardial infarction in Wanzhou District were high,and the burden of disease was heavy.The comprehensive prevention and treatment measures of acute myocardial infarction should be strengthened.
