目的探讨年龄因素对老年人急性心肌梗死临床特点的影响。方法将32~92岁共153例急性心肌梗死患者按年龄分为3组进行临床分析。结果随着年龄增长,≥70岁组女性患者明显增多,无痛性心肌梗死增多,心律失常、心力衰竭、心源性休克等并发症的发生率及病死率均明显高于60~69岁组及32~59岁组。结论年龄是急性心肌梗死发病及预后的重要影响因素之一,70岁以上老年人急性心肌梗死无痛性多见、并发症多、病死率高。
Objective To investigate the effect of age on the clinical features of elderly patients with acute myocardial infarction. Methods A total of 153 acute myocardial infarction patients 32 to 92 years old were divided into three groups by age. Results With the increase of age, the number of female patients ≥70 years old increased significantly, and the incidence of painless myocardial infarction increased. The incidence and mortality of arrhythmia, heart failure and cardiogenic shock were significantly higher than those of 60-69 years old And 32 to 59 years old group. Conclusions Age is one of the most important factors affecting the onset and prognosis of acute myocardial infarction. Acute myocardial infarction is more common in elderly patients over 70 years old with more complications and higher mortality.
