SUMMARY
The aim of the research was to describe the clinical charachters of male and female patients with stage II arterial hypertension (AH) of young and middle age with different gradations of galectin-3 plasma levels according to multiple linear stepwise regression analysis.Materials and methods: 160 patients with AH of different sex (male and female) and age (young (18–44 years), middle (45–60 years)) were examined (clinical, laboratory and instrumental). Multiple linear regression was used to determine the clinical presentation of patients with AH at different levels of the neurohormone (StatSoft's Statistica MultipleRegression v. 10.0 module). which were divided into groups that vi told for the entirely different patient characteristics. multiple linear regression was performed for each indicator separately and the results have been shaped in the form of regression equations.Results. Patients with young and middle-aged AH have been found to be relatively high (RH) levels of galectin-3 associated with: the presence of a complex of metabolic risk factors – obesity and dyslipidemia; in combination with multiple features of structural and functional changes in the cardiovascular system, such as the presence of concentric left ventricular (LV) hypertrophy in combination with myocardial relaxation disorders (?/e' aver>7.2) and signs of hemodynamic overload of the left atrium (LA) (LA volume index (LAVi)>34 ml/m2); the presence of valve dysfunctions in the form of mitral (1–2 degree) and aortic regurgitation (1 stage); the presence of structural remodeling of the carotid arteries (intima-media thickness (IMT)>0.91 mm). Plasma abdominal obesity was the most informative marker of RH galectin-3 in plasma, IMT>0.91 mm and LAVi>34 ml/m2.Conclusions. The association of plasma galectin-3 levels with various clinical and instrumental indicators indicates a certain effect of the neurohormone on the course of AH in young and middle-aged male and female patients. Of indisputable interest is the determination of the features of the course of AH and the clinical profile of patients at different gradations (relatively low (RL), relatively moderate (RM) and relatively high (RH)) galectin-3 plasma level.
