title: [Hormonal theory of heart failure with altered systolic function].
abstract: Heart failure (HF) is a major cause of morbidity and mortality in the developed countries. Hospital discharges and deaths from HF are regularly increasing. Therapies initially aimed at reversing hemodynamic abnormalities in HF, increasing cardiac output, decreasing intracardiac pressures, and blocking vasoconstriction. However, none of these therapies improved survival and some actually increased mortality. Now therapies for HF related to left ventricular systolic dysfunction have focused on counteracting compensatory neurohormonal activation. Several neurohormonal activations are present in HF supporting hemodynamics, but they appear to be deleterious in the long term on the myocardium, increasing progression of the HF and mortality. Blocking the renin-angiotensin-aldosterone system and the sympathetic system are now the mainstay of medical therapy in HF related to systolic dysfunction as they decrease mortality, hospitalisation rate and improve quality of life. Hence, the approach to patient with chronic heart failure should differ from that of patient with acute heart failure.
