In normal conditions, the heart has seven kinds of receptors on the cellular membrane surface which in normal conditions can be activated by several chemical and hormonal stimuli as for instance parcelary ischemic necrosis, due to myocardial failure, hemodynamic excessive over load without structural harm as in the case of aortic insufficiency whatever the cause, heart failure reduces expulsion fraction increases the ventricular volumenes and lowers cardiac “waste”. The decrease of the expulsion fraction becomes the trigger mechanism to liberate (generate) the compensatory mechanisms (“catecolamins” and “reninas” secretion). It has been demonstrated that if the cause of heart failure is not remedied the neurohumoral system remains persistently activated and it is the cause of the illness progression. The present pharmacological treatment for heart failure is meant to avoid the perpetuation of these neurohumoral mechanisms and, thus, avoid the progression of this illness and improve morbi-mortality of patients who suffer from it.
The most important knowledge that sustains the present heart failure therapy is summaryzed is this work so that the nurse can satisfy the demands of nowadays clinical world and come-up with short, and long-term strategies which aim at the efficient attainment of established goals for the patient.

Key words: Heart failure, neurohumoral mechanisms, pharmacological treatment.
