本文报道554例大于65岁急性心肌梗塞(AMI)患者,其中合并重度泵功能衰竭的109例。老年AMI合并重度泵衰的临床特征是:发生率与住院病死率随年龄增加而明显增加。≥65岁者分别为14.2%,18.9%,≥71岁者分别为32.8%,53.5%,≥81岁分别为57.1%,87.5%。性别间无明显差异。梗塞部位与发生重度泵衰及死亡关系中提示泵衰的发生随梗塞部位的扩展而成倍增加。下壁为8.3%,广泛前壁10.5%,广泛前壁+高侧壁21.9%,广泛前壁+高侧壁+下壁57.1%,病死率也显示此规律,后三者分别为19.4%,31.0%,54.2%。本组死亡41例而24小时内死亡29例(70.7%),提示死亡集中在这一时间内。在109例泵衰
This article reports on 554 patients aged> 65 years with acute myocardial infarction (AMI), including 109 cases of severe pump failure. Clinical characteristics of elderly AMI with severe pump failure are: the incidence and in-hospital mortality increased significantly with age. Patients aged ≥65 years were respectively 14.2% and 18.9%, those who were ≥71 years old were 32.8% and 53.5% respectively, and those aged ≥81 years were 57.1% and 87.5% respectively. No significant difference between the sexes. The relationship between the infarction site and the occurrence of severe pump failure and death suggests that the occurrence of pump failure multiplies with the expansion of the infarct site. The lower anterior wall was 8.3%, the wide anterior wall was 10.5%, the anterior wall was 21.9%, the anterior wall was 57.1%, the anterior wall was high, the fatality rate also showed this pattern, the latter three were 19.4% 31.0%, 54.2%. Forty-one patients died in this group and 29 patients died in 24 hours (70.7%), suggesting that the death was concentrated in this period. 109 cases of pump failure
