This literature review reflects modern ideas about the combination of heart failure (HF) and osteoporosis, common risk factors for these diseases, and pathophysiological mechanisms of metabolic bone diseases in HF. Despite a growing number of studies on the combined cardiovascular and skeletal system pathology, the relationship between a decrease in bone mineral density and HF risk remains poorly understood. Both conditions are common causes of disability, death, prolonged hospitalizations and a significant reduction in quality of life, while its combination exacerbates their course and increases the incidence of adverse outcomes, which is a heavy burden for a patient and health care in general. Keywords: heart failure, osteoporosis, bone mineral density, bone metabolism.

The redistribution of body composition components in heart failure (CHF) is an urgent and poorly understood issue. Despite the significant impact of a decrease in muscle mass, redistribution of fat mass on the course and prognosis of HF, body composition is rarely taken into account in the treatment of this disease. In this regard, the purpose of this review was to systematize the available data and draw the attention of clinicians to this problem. The data presented in the review make it possible to consider the components of body composition as controllable factors, the normalization of which improves the prognosis in patients with HF. The study of pathophysiological mechanisms for the development of body composition anomalies in HF will make it possible to search for new therapeutic targets. Assessment of body composition will make it possible to develop an individual strategy for the treatment of HF, including a set of non-drug measures.
