How effective is digitalis in the treatment of congestive heart failure?

The evidence suggests that digitalis glycosides do indeed improve ventricular performance through a sustained but moderate positive inotropic effect. This effect is more marked in failing than in nonfailing myocardium. The clinical studies suggest a moderate salutary effect in patients with chronic CHF who are in sinus rhythm. The drug can be given safely to patients with CAD and in combination with other medications when the physician is aware of those factors leading to increased sensitivity to digitalis.
