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 onset time characteristics and prognosis of hospitalized patients under 40 years old with acute myocardial infarction (AMI). Methods Among 218 patients with AMI, 106 patients (age ≤40 years) (group A) and 112 patients aged 60-75 years (group B). Retrospective analysis of clinical data, compared the incidence of the two groups of time distribution and hospital prognosis. Results The peak time of onset in group A was 6: 00-11: 59 (38.6%), followed by 0: 00-5: 59 (22.8%). The peak incidence of group B was 0: 00-5: 59 Accounting for 32.2%), followed by 6: 00-11: 59 am (30.0%). In-hospital mortality was lower in group A than in group B (5.7% vs.18.8%) (P <0.01). Conclusions Compared with elderly patients aged 60-75 years, AMI patients under 40 years of age are more morbid in the morning and the prognosis in the hospital is better.
