Features of gene polymorphism in comorbid patients with arterial hypertension and coronary heart disease

Objective: to assess the prospects of using genetic testing for early detection of patients with arterial hypertension (AH) with a high risk of developing coronary heart disease (IHD). Material and methods: we examined 100 patients with hypertension, who were divided into 2 groups: patients with hypertension without ischemic heart disease (62%, 62 people) and patients with hypertension with ischemic heart disease (38%, 38 people). All patients underwent a standard volume of diagnostic procedures, as well as molecular genetic research. Results: the specificity of the carriage of gene polymorphism was revealed, depending on the presence of isolated AH or AH in combination with IHD in patients. Patients with AH and IHD are characterized by the presence of the CC genotype and the C allele of the ΝΟS3 gene (p = 0,040 and p = 0,035), while the TT genotype of the T‑786C polymorphic marker of the NOS3 gene is characteristic of patients with isolated AH. Conclusion: the study of the genetic aspects of comorbidity is theoretically important for understanding the mechanisms of its formation. From a practical point of view, the opportunity to use modern genetic approaches for early screening of hypertensive patients with a high risk of developing cardiac comorbid pathology is valuable.
