Frequency of eNOS T786->C promoter polymorphism in 325 patients with acute coronary syndrome and 104 control per­sons and influence of this polymorphism on reactive hyper­emia and arterial stiffness were determined. Interrelation be­tween T/T homozygous, T/C heterozygous and C/C homozygous was 42,5%, 41,2% and 16,3%, correspondingly (in control - 40,4%, 53,8% and 5,8%; P<0.01 by X2-test). Higher degree of brachial arteries diameter increase in response to ischemia was estimated in patients with T/T genotype: 8,03 ± 0,71% compared to 5,55 ± 0,92 % in Т/С (P<0.05) and 5,30 ± 1,21 % in C/C genotypes (P<0.05). Speed of pulse wave spreading on carotid-radial and carotid-femoral arteries segments was also depended on patients genotype: in T/T genotype was 9,10 ± 0,15 and 8,68 ± 0,26 correspondingly, in T/C - 9,38 ± 0,18 and 8,74 ± 0,21, and in C/C carriers - 9,71 ± 0,22 and 10,02 ± 0,71 (P<0.05). Thus, the data obtained indi­cate on significant influence of T786->C polymorphism on integral parameters of functional condition of arterial vessels.

Keywords: allelic polymorphism, endothelial NO-synthase,endothelial dysfunction, speed of pulse wave arrival frequency,acute coronary syndrome.
