Determination of serum endogenous digitalis-like factor (EDF) concentration was carried out in 52 patients with chronic congestive heart failure with radioimmunoassay. The results showed that concentration of serum EDF in patients with chronic congestive heart failure was significantly lower than that in normal subjects (P less than 0.001). The lowering of serum EDF concentration was significantly negatively correlated with the severity of heart failure, r = 0.6475, P less than 0.001. Age had no significant effect on serum EDF concentration (P greater than 0.05). Serum EDF concentration rose after the heart failure was treated, but was still lower than that in normal subjects (P less than 0.01). Serum EDF concentration in patients with coronary heart disease was the lowest and in patients with hypertension the highest.
