脑缺血与诸多因素有关,但与心脏关系甚为密切,其中心力衰竭(简称心衰)即可引起脑缺血、缺氧症状,现将其有关方面的问题综述如下。一、脑缺血的病理生理学人脑的平均重量大约为1300～1500g,占体重的2.5～3％,而脑的血液灌流却占心输出量的16～17％。成人每分钟脑部输入血量为750～1000ml。静息 Cerebral ischemia and many factors, but with the heart is very close, which heart failure (referred to as heart failure) can cause cerebral ischemia, hypoxia symptoms, the relevant aspects of its problems are summarized below. First, the pathophysiology of cerebral ischemia The average weight of the human brain is about 1300 ~ 1500g, accounting for 2.5 to 3% of body weight, while the brain blood perfusion accounts for 16 to 17% of cardiac output. Adult brain blood volume per minute is 750 ~ 1000ml. Rest
