Hypothesis-generating for digoxin in valvular disease without overt failure; leaves open need for randomized confirmation before practice change.
Does digoxin reduce oxygen debt during exercise in patients with acquired valvular heart disease and cardiac enlargement?
Digoxin administration reduces oxygen debt during exercise in patients with cardiac enlargement and valvular disease but no overt heart failure symptoms, indicating improved circulatory functional status.
Kahler et al. (1963) studied Acquired valvular heart disease and cardiac enlargement (n=3). Digoxin vs. Placebo was evaluated on Oxygen debt following exercise. Digoxin administration reduced oxygen debt following exercise compared to placebo in three patients with valvular heart disease, with oxygen debt being 34% to 74% greater without the drug.
