[Use of digitalis in chronic heart failure: an unresolved problem?].
The role of digitalis in the treatment of patients with heart failure is still being debated. The DIG study, a trial which enrolled about 6800 patients with the aim at overcoming the doubts on efficiency and safety of digoxin, showed a neutral effect on mortality but there was a statistically significant decreased risk of hospitalization due to worsening heart failure in the digoxin group compared to the placebo group. The trial disclosed several problems about patient selection (many patients were on digitalis before the start of the trial), digoxin dosage, which seemed to be high, and about the true reported beneficial effects of this therapy. Finally the data available do not permit any evaluation on the use of beta-blockers and the association between digitalis and beta-blockers considering the properties of these drugs in suppressing orthosympathetic activation.
