2010年-2016年某医院急性心肌梗死发病和死亡统计分析

Analysis on Morbidity and Mortality of Acute Myocardial Infarction in the Hospital from 2010 to 2016

目的分析急性心肌梗死患者发病和死亡特点,为其防治工作提供科学依据。方法采用SAS9.4软件对2010年-2016年急性心肌梗死发病和死亡病例数据进行回顾性统计分析。结果发病例数男性大于女性(χ~2=354.58,P<0.0001),2010年—2016年男性和女性患者的发病构成比均有随年度增加而增加的趋势。死亡率男性高于女性,差异有统计意义(χ~2=24.30,P<0.0001)。发病患者(t=-17.16,P<0.0001)和死亡患者(t=-2.19,p=0.0300)的平均年龄均为女性大于男性。1~2月份发病人数(256例)占出院患者的比例最高(0.25%),时间分布差异有统计学意义(χ~2=20.62,P=0.0010)。发病患者(Z=-4.08,P<0.0001)和死亡患者(Z=-2.02,P=0.0437)的平均住院费用均为男性高于女性。住院日和住院费用存在正相关关系。结论加强男性、老年女性以及高峰季节急性心肌梗死的重点防治,加强住院日的管理,提高医疗质量,降低急性心肌梗死的发生。

Objective To analyze the characteristics of morbidity and mortality in patients with acute myocardial infarction, and provide scientific basis for its prevention and treatment. Methods The cases of acute myocardial infarction from 2010 to 2016 year were analyzed retrospectively by using the SAS9.4 software. Results The incident cases of acute myocardial infarction in male was markedly higher than that in female（χ~2=354.58, P0.0001）.The composition ratio of morbidity of the male and female increased with the increasing of annual year during 2010 to 2016 year. The mortality rate in male were greater than in female, and the difference was statistically significant（χ~2=24.30, P0.0001）. The average age of morbidity（t=-17.16, P0.0001） and mortality（t=-2.19,p=0.0300） in female were larger than that in male. The highest incident cases was in 1~2 month and there was statistically significant in the time distribution（χ~2=20.62,P=0.0010）. The average hospital charges of morbidity（Z=-4.08, P0.0001） and mortality（Z=-2.02, P=0.0457） in male were greater than that in female. There was a positive correlation between hospital stay and hospital charges. Conclusion We must enhance the prevention and control of acute myocardial infarction in the male, older female and peak season and pay attention to the management of hospital stay, so as to improve the medical quality and reduce the morbidity of acute myocardial infarction.
