许多心脏疾病可累及肝脏,临床上与原发肝脏疾病具有某些共同的特征,使鉴别诊断发生困难,因而延误治疗,影响预后。本文就这一问题作扼要综述.心脏疾病时肝功能的改变及其机理充血性心力衰竭时的肝脏变化众所周知,肝脏有双重血液供应,约66～83%通过门静脉,其余17～34%通过肝动脉。在正常情况下,肝的氧气供应约50%来自肝动脉。在充血性心力衰竭时,因心排出量减少,使肝血流量减少约1/3,肝脏不能摄取足够的氧,导致肝小叶中央性缺氧,从而引起肝细胞缺氧及坏
Many heart disease can affect the liver, clinical and primary liver disease has some common features, so that differential diagnosis difficult, thus delaying the treatment, affecting the prognosis. This article briefly reviews this issue. Changes in hepatic function and its mechanism during heart disease Liver changes during congestive heart failure It is well-known that the liver has a dual blood supply of about 66-83% through the portal vein and the remaining 17-34% artery. Under normal conditions, about 50% of the liver’s oxygen supply comes from the hepatic artery. In congestive heart failure, due to decreased cardiac output, reducing blood flow to the liver about 1/3, the liver can not take enough oxygen, leading to central lobular hypoxia, causing hypoxia and bad liver cells
