A lot of data has been accumulated at present on the metabolic and nutritional insufficiency in patients with chronic heart failure (CHF). Researchers have noted an actuality of the study of nutritional and metabolic insufficiency in CHF patients as independent factors affecting the course of CHF and because of its relationship with triggers of inflammation, sympathetic-adrenal system, and markers of functional state of the cardiovascular system (CVS). In some works attention has been given to relationship of nutritional and metabolic insufficiency with autonomic regulation of cardiac rhythm. Attempts have been made to systematize obtained data, create contemporary pathophysiological portrait of CHF development and highlight prevailing mechanisms of progression of the disease. This review summarizes accumulated data on nutritional insufficiency in patients with CHF and systematizes metabolic changes according to types of metabolism and CHF functional class. We have also made an attempt of creating figurative representation of pathophysiological mechanism of development of nutritional insufficiency in CHF. We have emphasized the problem of inadequate knowledge on contribution of inflammatory markers in development of nutritional insufficiency especially in patients with I-II functional classes of CHF. We also present suggestions concerning strategy of studying nutritional insufficiency in CHF, its classification according to CHF functional class, stratification of risk factors of its development, and the methods of its prevention and correction.
