The medical treatment of congestive heart failure.
The data herein presented provides persuasive evidence that in addition to diuretics, and probably digitalis (since all studies have included subjects taking this drug) patients with congestive heart failure should also be placed on a vasodilator regimen to slow the progression of the syndrome and to reduce its mortality. Firm recommendations for the choice of drug and the selection of patients likely to benefit from this treatment must await the results of further studies. At present, ACE inhibitors are preferred because they are usually better tolerated than conventional vasodilators and are clinically more effective. In regard to the question of when to begin vasodilator it is noteworthy that neurohormonal activation may occur early in the course of the disease, even before symptoms appear. If so, perhaps vasodilators should be initiated even in the asymptomatic stage of left ventricular dysfunction to prevent the progressive dilatation and deterioration that lead to clinical heart failure. The just published study of the efficacy of captopril in preventing the progression of left ventricular dilatation in patients with a recent anterior, transmural myocardial infarction supports this view. Further, ongoing studies, will help place these issues in their proper perspective.
