THE STUDY OF THE CONTENT OF THE ENDOGENOUS DIGOXIN-LIKE SUBSTANCE WITHIN THE PLASMA OF PATIENTS WITH CONGESTIVE HEART FAILURE / 西安交通大学学报(医学版)

In this study, endogenous digoxin-like substance (EDLS) in the plasma was measured by radioimmunoassay in patients with congestive heart failure The EDLS levels were significantly increased in patients with heart failure and were positively correlated correlated with the heart function state, Na~+/K~+-ATPasc activity in red cells and the electrolyte change in blood cells. We believed that digoxin-like substance may participatc in the process of the compensatory mechanirsms of the heart failure.
