老年急性心肌梗死临床特点分析

目的探讨老年急性心肌梗死(AMI)的临床特点。方法对比35例老年AMI与46例非老年AMI在首发症状、心肌梗死的部位、并发症及病死率的区别,进行假设检验。结果老年AMI组胸痛率低于对照组(P<0.05);无胸痛时,心力衰竭、胸闷发生率高于对照组(P<0.05);梗死部位无显著性差异(P>0.05);并发症中心力衰竭、急性脑血管意外、肺内感染、心律失常发生率高于对照组(P<0.05);病死率高于对照组(P<0.05)。结论老年AMI患者发生胸痛者较少,无胸痛时易发生心力衰竭和胸闷,心力衰竭、肺内感染、心律失常等并发症发生率高于年轻患者。

The study on the clinical characteristics of senile acute myocardial infarction

Objective To study the clinical characteristics of senile acute myocardial infarction（AMI）patients.Methods First symptoms,the parts of AMI,complications and mortality rate of 35 senile AMI patients and 46 AMI patients who were younger were compared,and hypothesis test was conducted. Results There was a significant difference in the rate of chest pain,heart failure, chest distress,heart failure of complications,acute cerebrovascular accident,intrapulmonary infection,arrhythmia and mortality between two groups（P〈0.05）,but was not in the parts of AMI（P〉0.05）.Conclusion The rate of chest pain of senile AMI patients was lower,but the rate of heart failure,chest distress,heart failure of complications,acute cerebrovascular accident, intrapulmonary infection,arrhythmia and mortality was higher than that of these who were younger.
