本文用放射免疫方法测定26例老年人慢性充血性心力衰竭患者和20例健康人血清EDF浓度,结果发现,老年人慢性充血性心力衰竭患者血清EDF浓度明显低于正常,心力衰竭程度越重,血清EDF浓度越低;心力衰竭纠正后,血清EDF浓度明显升高;合并有房颤患者血清EDF浓度低于窦性节律患者,但无统计学上显著性差异。
In this paper, radioimmunoassay method for the determination of serum concentrations of EDF in 26 elderly patients with chronic congestive heart failure and 20 healthy subjects and found that the elderly patients with chronic congestive heart failure serum EDF concentrations were significantly lower than normal, the more severe heart failure, The lower the serum EDF concentration, the higher the serum EDF concentration after the correction of heart failure. The serum EDF concentrations in patients with atrial fibrillation were lower than those in sinus rhythm, but there was no statistically significant difference.
