[Heart Failure in Patients With Preserved Ejection Fraction - Pumping Heart Failure?]

The review analyzes literature data on the phenomenon of chronic heart failure as a clinical syndrome of hypoperfusion of organs and systems of the body due to multiple causes of pumping inadequacy of the circulatory system. Special attention is paid to diastolic heart failure of different origin. Attention is drawn to the fact that integrated quantitative characteristic of CHF of any origin is indexed cardiac output (CO) rather than ejection fraction, and that allocation of systolic and diastolic CHF is a relatively conventional division concept. It has been shown that in heart failure of any origin, cardiac output is reduced, resulting in diminished supply of oxygen and substrates to tissues of the body. The variety of causes of heart failure with preserved ejection fraction makes it impossible to correct hemodynamic disturbances by "standard set" of drugs. Normalization of the balance between delivery of oxygen / substrates and metabolic demands of tissues may be a key approach to the treatment of diastolic heart failure of different origin.
