【 摘 要 】

Aim. To study the parameters of aortic stiffness and polymorphisms of matrix metalloproteases genes MMP2 (-1306) and MMP9 (-1564) in patients with arterial hypertension (AH) of young and middle age.Material and methods. Totally, 58 patients studied with AH, age 25-60 y.o., and 59 healthy volunteers. The pulse wave velocity (PWV) assessed, and augmentation index (arteriography on TensioClinic TL1, Hungary). The specimens of DNA extracted, from blood leucocytes, and gene typing of promotor regions of the genes MMP2 (-1306) and MMP9 (-1564).Results. Genotypes MMP2 (-1306) (CT and ТТ) are found in AH patients with the signs of metabolic syndrome (MS) 1,72 times more commonly than in controls (p=0,23). Genotypes MMP9 (-1564) (CT and ТТ) are slightly more common in the general AH group comparing to controls (OR=1,4; p=0,39). In AH patients with no MS signs the genotypes MMP9 (-1564) (CT and ТТ) are predominant and found 2,66 times more frequently, than in the healthy (р=0,04). In cases of high PWV in AH, genotype MMP9 (-1564) (СТ and ТТ) is found 1,9 times more often than in controls with AH and normal PWV with no statistical significance (р=0,14).Conclusion. The polymorphism MMP9 (-1564 C/T) finding in AH patients can be used for prediction of additional risk for cardiovascular catastrophes with the individualized monitoring of collected factors.
