目的:了解甲状腺功能亢进(甲亢)性心脏病心力衰竭(甲亢并心衰)患者血浆内源性洋地黄样因子(EDF)浓度动态变化的意义.方法:用放射免疫法测定了45例甲亢并心衰患者和33名正常人血浆EDF浓度.结果:甲亢并心衰组血浆EDF浓度明显低于正常组［甲亢并心衰组(0.45±0.18)μG/L,正常组(0.66±0.22)μG/L,P＜0.01］,心衰纠正后血浆EDF浓度明显升高［治疗前(0.42±0.17)μG/L,治疗后(0.61±0.24)μG/L;P＜0.01］.结论:甲亢患者的EDF分泌不足可能与心衰的发生有关.“,”Objective: To observe the dynamic changes of plasma endogenous digitalis like factor (EDF) in heart failure induced by hyperthyroid heart disease Methods: 45 cases of heart failure patients induced by hyperthyroid heart disease and 33 healthy subjects were observed, and their plasma EDF were determined with radioimmunoassay Results: The levels of plasma EDF in hyperthyroid heart failure patients were significantly lower than those in healthy ...
