Now there is a relevant development of the new biomarkers capable to serve as the instrument of early diagnostics of a disease for the purpose of selection of a pharmacotherapy and further monitoring of its efficiency. Galektin-3 is the atypical representative of the family of galektin. Its participation in fibrosis, remodeling of heart, the immunologic answer and inflammatory reactions are shown. Prognostic value is discussed and diagnostic opportunities of Galektin-3 at CHF are widely studied and take root into clinical practice. Now a great deal of research devoted to the studying of Galektin-3, possibilities of its use as a biomarker at diagnostics, forecasting of outcomes and the choice of therapeutic strategy at other cardiovascular diseases has been conducted.

Hypertrophic cardiomyopathy (HCM) is the most common genetic heart disease, with a prevalence of approximately 1 in 500 among the adult cohort. It is a common etiological factor of sudden cardiac death in the young and a common cause of morbidity and mortality in all age groups. HCM is characterized by a complex pathophysiology, which is manifested by a heterogeneous clinical picture. The mechanism of development of this variant of hypertrophy is not fully understood. Currently, only a part of the genetic mutations that correlate with the development of this pathology has been identified. In this regard, the issue of genetic diagnosis of HCM is very relevant, as it will allow us to conduct advanced screening. A very important task is to develop a personalized approach in the conservative and surgical treatment of people suffering from this variant of cardiopathy.
