About

Digoxin is the oldest, market-authorized drug for heart failure (HF), and very cheap. A large trial with digoxin, the DIG trial, executed in the early nineties revealed a highly significant reduction in HF hospitalizations, but no effect on mortality. A post-hoc analysis of the DIG trial suggests that low serum concentrations of digoxin may not only improve HF hospitalizations but also mortality in chronic HF patients. To confirm these retrospective analyses, a prospective, randomized, placebo-controlled trial is necessary to establish the position of digoxin in the contemporary treatment of HF. Therefore, the investigators examine whether low-level, aiming for serum concentrations 0.5-0.9ng/mL, digoxin is beneficial in HF patients with reduced or mid-range ejection fractions (LVEF <50%).
