[Digoxin: the results of the DIG study in the XXI century].

Abstract

After the report that there was no statistical significance in the general mortality of the DIG study, the indication of digoxin in the treatment regimens for congestive heart failure (CHF) drastically decreased. Post hoc studies that reassessed the DIG study data, indicated that an aspect that was not considered in this multicenter study has a critical influence on the prognosis of patients: the serum levels of digoxin. Regarding those that received a placebo, the general mortality and hospitalization were decreased in patients with a digoxin level < 0.9 ng/ml. At the first study that assessed the influence of digitalis in an experimental model of CHF, we verified in our lab that female rats with congestive syndrome secondary to myocardial infarction have a prolonged survival when undergoing treatment with digitoxin. The current information recommends that the merits of digoxin continue to be analyzed in order to adequately establish its importance in the treatment of CHF.
