[New inotropic drugs in chronic cardiac insufficiency: progress or wrong track]. / Les nouveaux inotropes dans l'insuffisance cardiaque chronique: progrès ou faux pas.

The first results of the long-term treatment of chronic heart failure with inotrope positive medications are disappointing, especially in that survival is not prolonged and even a greater mortality is suggested. Is it because of the regular failure of specific medications, of a class of medications or because the overall concept of inotropism stimulation during chronic heart failure should be condemned? The mechanisms of inotropism of normal muscles or muscles in human chronic heart failure are reviewed as well as the various pharmacological means available to stimulate inotropism.
