目的 :研究 75岁以上老年人急性心肌梗死 ( AMI)的临床特点。方法 :对 63例 75岁以上老年 AMI进行临床分析 ,并与同期 161例 60～ 74岁和 176例 60岁以下 AMI患者进行对比。结果 :75岁以上老年女性 AMI患者明显增多 ,无痛性 AMI多 ( 34.9% ) ,血流动力学受损的体征和并发症、泵衰竭引起的室上性心律失常和房室传导阻滞以及死亡率均比其他两年龄组多见 ,而梗死范围、死亡原因三组间无明显差异。结论 :75岁以上老年无痛性 AMI多见 ,病情严重程度高 ,并发症发生率高 ,死亡率高 ,而性别对 AMI的发生和预后无明显影响
Objective: To study the clinical features of acute myocardial infarction (AMI) in the elderly over 75 years old. Methods: The clinical data of 63 AMI patients aged 75 years and above were analyzed and compared with 161 AMI patients aged 60-74 years and 176 cases under 60 years old in the same period. Results: The AMI patients older than 75 years old were significantly increased with more painless AMI (34.9%), signs and complications of hemodynamic impairment, supraventricular arrhythmias and atrioventricular block induced by pump failure, and Mortality were more common than the other two age groups, and the infarct size, the cause of death was no significant difference between the three groups. CONCLUSIONS: Painless AMI is common in elderly patients over 75 years of age with high severity, high complication rate and high mortality rate, while gender has no significant effect on the occurrence and prognosis of AMI
