40岁以下急性心肌梗死患者发病时间特征及其院内预后分析

An analysis on the hour feature of acute myocardial infarction attack and in-hospital prognosis in patients aged under forty

目的探讨40岁以下急性心肌梗死(AMI)患者的发病时间特征及其住院期间的预后。方法 AMI患者218例中,年龄≤40岁106例(A组),年龄60-75岁112例(B组)。回顾性分析临床资料,比较两组发病的日时间分布及院内预后。结果 A组发病高峰时间是上午6:00-11:59(占38.6%),其次是0:00-5:59(占22.8%);B组发病高峰时间是0:00-5:59(占32.2%),其次是上午6:00-11:59(占30.0%)。A组院内死亡率低于B组(5.7%vs.18.8%)(P<0.01)。结论与60-75岁的老年患者比较,40岁以下的AMI患者上午发病者较多,院内预后较好。

Objective To investigate the hour feature of acute myocardial infarction （AMI） attack and in-hospital prognosis in the patients under 40 years. Methods A total of 218 patients with AMI was assigned into two groups of A≤40 years old, 106 cases） and B （60-75 years old, 112 cases）. The hour [eature of AMI attack and the in-hospital prognosis were compared by retrospec- tively analyzing clinical data of 218 cases. Results The peak period of time for AMI attack was 6：00- 11 ： 59 am（accounting for 38.6 %） in group A, which was 0 ： 00-5 ： 59 am （ accounting for 32.2 % ） in group B. The second peak period of time for AMI attack was 0：00-5：59 am（accounting for 22.8%） in group A,which was 6：00-11：59 am（accounting for 30.0%） in group B. The in-hospital mortality was lower in group A than that in group B（5.7%vs. 18. 8%）（P〈0. 01）. Conclusion Compared to people aged 60-75 years old, the peak period of time for AMI attack is 6：00-11：59 am with a lower in-hospital mortality in those aged under 40 years.
