急性心肌梗塞青年病人和老年病人发病因素临床特点及死亡率比较

Comparison of risk factors,clinical features and mortality in acute myocardial infarction between young and elderly patients

目的比较不同发病因素作用于急性心肌梗塞青年病人和老年病人的不同特点。方法本文将５２９例急性心肌梗塞（ＡＭＩ）病人分为青年组和老年组，对危险因素及临床各变量进行对比分析。结果ＡＭＩ老年病人比青年病人明显增高。青年病人中男性占大多数（８７１％），老年病人中女性百分率比较高（４０７％）。危险因素表明青年组以吸烟、高脂血症及家族史为常见，而老年组以高血压、糖尿病及高脂血症为常见。临床特征表明青年组疼痛症状典型、梗塞部位较局限，合并症较少，平均住院天数较短，无住院死亡，预后较好。老年组症状多不典型，多部位梗塞多。

Objective A young group and an elderly group with acute myocardial infarction were analysed in a fotal of 529 cases. Methods The risk factors and the clinical variables markedly increased in the elderly patients compared with the young patients.WT5HZResults The male were predominant in the young group(87.1%),while the female accounted for a large percentage in the elderly group(40.7%).Risk factor analysis revealed that cigarette smoking,hypercholesterolemia and family history were more frequently found in the young patients,while hypertension,diabetes and hypercholesterolemia were more frequently found in the elderly patients.Clinical features showed that the young patients had a severe pain in chest,localized infarction,less complications,shorter period of hospitalization,no in-hospital mortality and favorable prognosis.The elderly patients had no marked symptoms,ertensive infarction,associated with an increased length of hospitalization and in-hospital mortality(8.4%).The difference between the two groups was very apparent(P<0.01). Conclusion The risk factors AMI of is definit.
