为探讨低血压在脑梗死中的作用,作者对135例心脏骤停或心室纤颤复苏后1日至数周内死亡者的脑(全部病例均在40岁以上)进行肉眼和显微镜检查。结果:大多数病例有广泛冠状动脉粥样硬化,但仅少数有严重的脑动脉粥样硬化,说明动脉粥样硬化在脑比冠状动脉发生为晚。患者平均年龄也随脑动脉粥样硬化的程度而增大。新近心肌梗死者74例,陈旧性心肌梗死或弥漫性心脏纤维化者32例,其他原因(如 To investigate the role of hypotension in cerebral infarction, we examined macroscopically and microscopically the brain of all 135 patients who died within one day to several weeks after cardioversion or ventricular fibrillation resuscitation, all of whom were over 40 years of age. RESULTS: In most cases, there was extensive coronary atherosclerosis, but only a few had severe cerebral atherosclerosis, suggesting that atherosclerosis occurs later in the brain than in coronary arteries. The mean age of patients also increases with the degree of cerebral atherosclerosis. 74 cases of recent myocardial infarction, old myocardial infarction or diffuse cardiac fibrosis in 32 cases, other reasons (such as
