农村居民急性心肌梗死住院及死亡人数变化趋势

The trend of changes in the rate of admission and mortality among rural patients with acute myocardial infarction

目的 估价农村居民急性心肌梗死(AMI)发病率与死亡率的变化趋势。方法 回顾性调查了1976～1995年AMI住院及死亡病例,以每5年为一个阶段进行统计、对比。结果 第4阶段与第1阶段比较,农村AMI住院人数增加了264.6%,死亡例数增加了129.4%,住院病死率下降了37.2%,女性住院人数增长显著高于男性,分别为375.0%和207.4%(卡方检验,P<0.05);女性住院病死率也高于男性,分别为19.8%和13.6%(卡方检验,P<0.05)。结论 农村居民AMI发病率、死亡率均呈上升趋势。

Objective To evaluate the trend of changes in the rates of incidence and mortality of acute myocardial infarction (AMI) in rural population. Methods Analysis was made on the clinical data of hospital admission and mortality rate of patients with AMI in rural areas during 1976 and 1995 under every 5-year interval: 1976-1980,1981-1985,1986-1990 and 1991-1995. Results The number of admission of patients with AMI in rural areas in these four periods were 82,118,177 and 299 cases respectively. The number of deaths were 17,23,30 and 39 caese and the fatality rates among inpatients were 20.7%, 19.5%, 16.9% and 13.0% respectively during these periods. The number of admission in females increased faster than that in males, the increase in percentage was 375.0% versus 207.4% ( P < 0.05 ).In-patient fatality rate in females was significantly higher than that of males (19.8% vs 13.6%, P < 0.05 ). Conclusion The rates of incidence and mortality of AMI have increased while inpatient fatality has decreased in rural population in the last 20 years.
