The aim of the work was to optimize the diagnosis of myocardial dysfunction in men, residents of Podillya, taking into account the plasma concentration of brain natriuretic peptide (BNP) and polymorphism of the corresponding gene under conditions of comorbidity of essential hypertension (EH) with left ventricular hypertrophy (LVH) and type 2 diabetes mellitus (T2D). We examined 211 men: 79 persons without the signs of cardiovascular diseases, 62 patients with EH 2 and chronic heart failure (CHF) 0-I functional classes (FC) according to NYHA Classification and 70 – with EH 2 combined with T2D and CHF FC I-II. The examination included the determination of plasma concentration of BNP, the brain natriuretic peptide gene polymorphism (polymorphic locus T-381C), indices of doppler-echocardiography. The mathematical processing was performed using the standard statistical package Statistica 10. During the study, we calculated the primary statistical indicators, identified differences between groups on statistical grounds, made correlation and discriminant analysis. Diastolic dysfunction (DD) of the left ventricle (LV) was diagnosed in 45.16% of patients in the group with EH 2, and 90% in the group of comorbid patients. It was determined that men, residents of Podillya, with presence and absence of T2D, have dominating T381C genotype of the BNP gene (p0.05). Lower plasma concentration of BNP that is peculiar for homozygous T381T genotype, in comparison with carriers of allele C of BNP gene and the average values of this biomarker in patients with DD may affect its informativeness in the diagnosis of myocardial dysfunction and requires a lower level of diagnosis. Appropriate borderline levels of BNP were determined for early diagnosis of DD in carriers of polymorphic variants of the BNP gene in men, residents of Podillya, with comorbid course of EH 2 and T2D. It is recommended to determine the genotype of the corresponding gene (polymorphic locus T-381C) and plasma level of BNP and focus on the calculated borderline levels of BNP to optimize the diagnosis of myocardial dysfunction in comorbid patients with EH 2 and T2D. For carriers of the T381T genotype it is ≥55.57 pg/ml, for carriers of the C allele (heterozygous T381C and homozygous C381C) of the BNP gene it is ≥69.13 pg/ml Доп.точки доступа: Antoniuk, Ya. O.
