title: [Defining the concept "cardiac insufficiency"].
abstract: The paper analyzes various definitions of the concept "heart failure" and shows disadvantages of these definitions. Based on the analysis of the time course of myocardial functional and structural changes during various pathological processes, heart failure is defined as a condition characterized by lower cardiac reserve potentialities. A process of cardiac desynchronization is analyzed as a predisposition to heart failure.
