THE ROLE OF DETERMINING SOME GENETIC POLYMORPHISMS IN PATIENTS WITH NEURO-CIRCULATOR ASTHE- NIA AND HYPERTENSIVE HEART DISEASE OF STAGE I

Abstract

Arterial hypertension is a multifactorial disease, a significant role in the pathogenesis of which is played by a genetic factor. In recent years, many studies have been carried out to identify genes in various diseases, including arterial hypertension, and candidate gene databases have appeared, to which the results of these studies have been added. There are known polymorphisms of genes associated with the development of arterial hypertension, as well as with a change in the pharmacodynamics of antihypertensive drugs. The following genes and the peculiarities of metabolism and activity of pressor systems associated with their polymorphisms are most studied: genes of the cytochrome system (CYP2D6, CYP2C9, CYP11B2); genes of the renin-angiotensin-aldosterone system: ACE (angiotensin-converting enzyme gene), AGT (angiotensinogen gene), AGTR1 and AGTR2 (angiotensin 1 and angiotensin 2 receptor genes). The objective of the study was to study the frequency of detection of gene polymorphisms associated with the development of arterial hypertension in patients with hypertensive neurocirculatory asthenia and stage I hypertension. A total of 77 conscripts and contract employees between the ages of 18 and 40 were examined. Using the amplifier, the following genes were studied by polymerase chain reaction and detection: the p-450 cytochrome gene (CYP11B2) and the AGT renin-angiotensin-aldosterone system gene: 704 T> C. Polymorphisms of candidate genes for arterial hypertension were found in 100% of the examined. AGT polymorphisms: 704 T> C and CYP11B2 were more often detected in stage I hypertension than in hypertensive neurocirculatory asthenia. Conducting genetic research at a young age in patients with hypertensive neurocirculatory asthenia will reveal a risk group for the development of hypertension.
