目的探讨高龄急性心肌梗死的临床特点。方法通过对３１例８０岁以上高龄急性心肌梗死（ＡＭＩ）患者进行临床分析，并随机与６０～７０岁及５９岁以下ＡＭＩ患者进行对比观察。结果高龄组多于秋冬两季发病，且多数患者于发病前无明确诱因及典型的临床症状，非Ｑ波性心梗发生率、合并症、伴发症、死亡率均较老年组及非老年组明显高（Ｐ＜０．０５）。结论高龄急性心肌梗死临床症状多不典型，合并症、伴发症、死亡率均高于老年组及非老年组。

Methods The clinical data of 31 AMI patients aged over 80 years were analyzed and compared with AMI patients 60 to 70 years and below 59 years old. Results There was more incidence in the elderly group than in the autumn and winter seasons, and most of the patients had no definite predisposition and typical clinical symptoms before onset, and the incidence of non-Q wave myocardial infarction, complications, complication and mortality were significantly higher than those in the elderly and non-elderly Group was significantly higher (P <0.05). Conclusion The clinical symptoms of elderly patients with acute myocardial infarction are atypical, and the complications, complications and mortality are higher than those in the elderly and non-elderly patients.
