Efficacy and safety of low‐dose digoxin in patients with heart failure. Rationale and design of the DECISION trial

Aims Digoxin is the oldest drug in cardiovascular (CV) medicine, and one trial conducted >25 years ago showed a reduction in heart failure (HF) hospitalizations but no effect on mortality. However, later studies suggested that the dose of digoxin used in that trial (and other studies) may have been too high. The DECISION (Digoxin Evaluation in Chronic heart failure: Investigational Study In Outpatients in the Netherlands) trial will examine the efficacy and safety of low‐dose digoxin in HF patients with reduced or mildly reduced left ventricular ejection fraction (LVEF) with a background of contemporary HF treatment. Methods The DECISION trial is a randomized, double‐blind, parallel‐group, placebo‐controlled event‐driven outcome trial which will investigate the efficacy and safety of low‐dose digoxin in patients with chronic HF and LVEF
