The application of pharmacogenetic testing was analyzed in patients treated at the center of personalized medicine, in order to analyze gene polymorphism frequency - response predictors to indirect anticoagulants therapy, estimation of the warfarin dose selection time, the hospitalization duration. The presence of VKORC1 and CYP2C9 polymorphisms or homozygous polymorphisms combinations is quite common in the Russian population: CYP2C9*2 polymorphism (15.3%) was observed in 8 patients, CYP2C9*3 (9.6%) in 5 patients. VKORC1 gene A allele was detected in 18 patients, accounting for 34.6% of the whole group. In patients with this polymorphism warfarin administration according to the traditional algorithm often leads to excessive anticoagulation and bleeding. Initiation of warfarin therapy according to the scheme taking into account genotyping significantly increases the treatment safety and reduces the adverse events incidence in this group of patients.

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 aim of the treatment of hypertension in patients with overweight is not only normalization of blood pressure, but also improvement of endothelial function, reduction of insulin resistance and lipid metabolism. Some of the drugs with a broad therapeutic spectrum and huge evidential base, - I1-imidazoline-receptor agonists can be applied in both monotherapy and as a part of the combined therapy in overweight patients.
