Relevance. At present, it is urgent to develop new biomarkers that can serve as a tool for early diagnosis of the disease in order to select pharmacotherapy and further monitor its effectiveness. The goal is to evaluate the clinical value of the definition of galectin-3 in patients with chronic heart failure (CHF). Materials and methods. The study included 53 patients (31 women, 22 men) with CHF II-III functional class (FC) of the New York Heart Association (NYHA). The mean age of the patients was 71 years (95% confidence interval 68.99-74.37). A group of patients with NYHA FCh II CHF made up 14 people, a group of patients with NYHA-39 CHF III FC. The median of the initial level of the N-terminal brain natriuretic peptide (NT-proBNP) was 65.7 pmol/L, the median of the initial level of galectin-3 - 8.37 pmol/l. Results. The relationship of increased level of galectin-3 with reduced ejection fraction,% (r=-0.26, p=0.04), increased creatinine level (r=0.26, p=0.04) and increased level of NT-proBNP plasma (r=0.3, p=0.02). With other clinical indicators, such as systolic and diastolic blood pressure, heart rate, body mass index, 6-minute walk test, left ventricular mass index, glucose level, total cholesterol, glomerular filtration rate, no statistically significant association was found. A moderate correlation was obtained between the levels of NT-proBNP and galectin-3 plasma (r=0.3, p=0.02). Reduction in the level of galectin-3 after the treatment was detected in 84.3% of patients. The conclusion. Galectin-3 can serve as an additional diagnostic biomarker of CHF.

The reviewsummarizes the results of clinical trials in which galectin-3 was assessed as biomarker of heart failure. In addition, most relevant information on galectin-3 received in in vitro and in vivo research is given with respect of heart failure.
