心力衰竭(heart failure,HF)或心功能不全,泛指在有适量静脉回流的情况下,心脏排出的血液不足以维持组织代谢需要的一种病理状态,并形成一个临床综合病征。 HF可分为多种类型。根据发病的急慢,可分为急性和慢性HF;视受累的心室不同,可分为左心衰竭、右心衰竭和全心衰竭;视心排血量的下降是绝对抑或相对,可分为低排血量型HF和高排血量型HF;而心室充盈受阻所致的HF则称为顺应性减低型HF。 Heart failure (HF) or cardiac insufficiency refers to a state of the pathology in which the blood excreted in the heart is insufficient to maintain tissue metabolism in the presence of adequate venous return and forms a clinical syndrome. HF can be divided into many types. According to the onset of acute and chronic, can be divided into acute and chronic HF; depending on the different ventricles, can be divided into left heart failure, right heart failure and heart failure; decreased cardiac output was absolute or relative, can be divided into Low-level HF and high-level HF-type HF; and ventricular filling obstruction caused by the HF is called compliance-reduced HF.
