Abstract
In 1785 William Withering in his accounts of Foxglove, reported the beneficial effects of digitalis in dropsy [1]. Thus, the use of drugs with positive inotropic effects in the management of heart failure was introduced in the clinical practice. Catecholamines with positive inotropic effects appeared several decades after the introduction of digitalis and presently a large number of such catecholamines are available for the clinical use and a growing number of such agents are undergoing clinical investigation. Non-glycoside, non-catecholamine inotropic agents have also been developed and enthusiasm continues to introduce newer inotropic agents with novel modes of action in the management of both acute and chronic heart failure. The background for this increasing interest in developing inotropic agents is based on the fact that the inotropic agents have the potential to correct one important functional abnormality, that is, the reduced contractile function that frequently initiates heart failure. Although the principle goal for the use of inotropic agents is to enhance contractile function, it needs to be realized that the modes of action and the relative potencies of various inotropic agents are not similar and understanding the mechanism of action of these various inotropic agents and their hemodynamic effects has direct clinical relevance in their use in the management of patients with heart failure.
