非典型性老年急性心肌梗塞43例临床分析

CLINICAL ANALYSIS ON 43 CASES OF ATYPICAL SENILE ACUTE MYOCARDIAL INFARCTION

本文通过随机抽样调查80例60岁以上老年急性心肌梗塞患者,依临床症状分为非典型组和典型组进行对比观察,显示症状非典型性老年急性心肌梗塞发病率达53.8%(43/80);随着年龄增长而患病增加(P<0.05);梗塞部位以下壁为多(P<0.01);常合并心衰、心律失常、心源性休克(P<0.05～0.01);伴发症以慢性支气管炎肺气肿以及慢性胃肠疾患为主(P<0.01);急性期病死率达32.6%(14/43);较典型性老年急性心肌梗塞具有显著性差异(P<0.05)。

Through investigation on 80 patients with senile a- cute myocardial infarction by random sampling and com- parative observation on the atypical group and typical group according to the clinical symptoms,it was shown tlhat the attack rate of the former reached 53.8%(43/ 80)and it became higher with the increase of age(P< 0.05). Myocardial infarction often appeared on the low- er wall(P<0.01)with incorporation cardiac failure, arrhythmia and cardiogenic shock(P<0.05～001). It might be accompanied with the chronic bronchitis and chronic obstructive emphysema and chronic gastrointestinal tract disease(P<0.01). The oase-fatality rate in the acute period was up to 32.6%(14/43),significantly different from relatively typical senile acute myocardial infarction(P<0. 05).
