Although there were indications that digitalis was beneficial in heart failure, it has only now been scientifically proven that digitoxin has a significant positive effect in heart failure due to reduced pumping function and insufficient emptying of the left ventricle—known in medical terms as HFrEF (heart failure with reduced ejection fraction).
