Heart failure is a disorder of the circulation, not merely a disease of the heart. Heart failure develops not when the heart is injured only, but as a consequence of the actions of the compensatory mechanisms and when compensatory hemodynamic and neurohormonal mechanisms are overwhelmed and exhausted
