老年与中青年急性心肌梗死患者临床特点对比分析

目的探讨老年人急性心肌梗死的临床特点。方法回顾性分析92例60岁以上老年急性心肌梗死（老年组）患者及70例非老年急性心肌梗死（中青年组）患者的临床资料，分析起病诱因、首发临床表现、梗死部位、伴发症、并发症以及死亡率。结果老年组多数患者于发病前无明显诱因及典型的临床症状，梗死部位较广泛，非ST段抬高型心肌梗死的发生率、并发症、伴发症、病死率均较中青年组高，差异有统计学意义（ P＜0.05）。结论老年人急性心肌梗死发生率高，且以临床表现不典型者多见。

Comparative Analysis of Clinical Features of Acute Myocardial Infarction in the Elderly and Young

Objective To study clinical features of atypical acute myocardial infarction among the elderly.Methods 92 patients above 60 years old with acute myocardial infarction and 70 patients less than 60 years old with acute myocardial infarction were selected from January 2005 to January 2013 ,as the old group and the young group respectively.Statistic of the two groups of patients were retro-spectively analyzed ,including inducement ,first clinical manifestation ,infarct location ,comorbidities ,complications ,and mortality.Results Most patients in the elderly group didn’t have obvious inducements and typical clinical symptoms ,while having extensive in-farct locations ,and the rates of non_ST_segment elevation myocardial infarction incidence ,comorbidities ,complications and mortality were significantly higher than young group （ P〈0.05）.Conclusions The incidence rate of atypical acute myocardial infarction in the elderly is high ,soheightened awareness ,early diagnosis ,early treatment are required to prevent the occurrence of complications or death.
