Nat MedPublished

  • Randomised controlled trial
  • double-blind
  • placebo-controlled

Authors' conclusion

The results of this trial indicate that in patients with heart failure and reduced or mildly reduced ejection fraction, low-dose digoxin did not significantly reduce the composite endpoint of total worsening heart failure events or cardiovascular mortality.
