老年人急性心肌梗死临床特点探讨

Clinical Analysis of the Aged Patients with Acute Myocardial Infarction

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 15 3例急性心肌梗死病人按年龄分为 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死亡率均明显高于 6 0～ 6 9岁组及 32～ 5 9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 ,死亡率高。

Objective: To explore the clinical characteristics of acute myocardial infarction were mainly affected by the age of the patients.Methods:Patients of AMI were divided into 3 groups ,70 years and over (87 cases),between 60 to 69 years (36 cases) and between 32 to 59 years (30cases).The clinical features were compared.Results: The number of females and the painless myocardial infarction patients were more in group of 70 years and over . The group of 70 years and over had more complications such as arrhythmias cardiac failure and cardiogenic shock and higher mortality rate than the other two groups.Conclusion: The factor of age is an important predictor of the onset and outcome of AMI.The number of painless AMI ,the complication rate and mortality rate were higher in the group of 70 years and over.
