Recent medical literature is replete with articles i concerning the treatment of congestive heart failure, acute^1-7 and chronic,^9-16 with agents that increase venous capacitance and reduce preload, and with those that decrease systemic arteriolar resistance and reduce afterload. These concepts are not new^17,18 and their recent widespread acceptance as therapeutic modalities in the treatment of congestive heart failure should not obscure the primary role of digitalis glycosides.^19-22 This fact is best perceived after a review of basic concepts and a classification of the etiologies of congestive heart failure.

If congestive heart failure is due to failure of myocardial fibers, the essentials of pathophysiology are as follows: (1) the velocity of myocardial fiber contraction varies inversely with the load moved; (2) at any given load, the velocity of contraction can be enhanced by increasing fiber length (heterometric autoregulation), or by sympathetic stimulation (homeometric autoregulation), sympathomimetic drugs, and . . .
