测定了20例正常人及34例充血性心力衰竭(CHF)患者血浆β-内啡肽(β-EP)含量及部分患者的心脏泵功能参数(CO、CI).结果表明:CHF患者β-EP含量显著高于正常人;β-EP含量与心力衰竭严重程度呈正相关,与心力衰竭病因无关,而与CO、CI呈负相关.提示:CHF患者血浆β-EP含量显著升高,β-EP含量可以反映心力衰竭的严重程度. Β-EP in 20 normal subjects and 34 patients with congestive heart failure (CHF) were measured, and cardiac pump parameters (CO, CI) were measured in some patients.The results showed that β- EP content was significantly higher than the normal people; β-EP content and the severity of heart failure was positively correlated with the etiology of heart failure has nothing to do with the CO, CI was negatively correlated.It suggested that: the plasma levels of β-EP in CHF patients significantly increased, β- EP content can reflect the severity of heart failure.
