Background: Pulse wave velocity is a strong predictor of cardiovascular events and mortality. It is known that NO can influence arterial stiffness through vascular tone regulation. The presence of eNOS mutations can influence arterial stiffness. Purpose of the study was to investigate the relation between 894G>T mutation and arterial stiffness.

Material and method: The study included 70 subjects (63.4% women), in whom the 894G>T polymorphism (the PCR method) and arterial stiffness (using the TensioMedTMArteriograph) were determined. The mean age of the subjects was 59.81± 11.01 years, without significant sex differences.

Results: The distribution depending on the presence of genotypes was for the 894GT mutation as follows: 42.3% of the subjects were negative (GG), 40.8% heterozygous (GT) and 16.9% homozygous (TT). No significant differences were found between sexes (women vs men) regarding the presence of genotypes: GG 44.4% vs 38.5%, GT 44.4% vs 34.6%, TT 11.1 vs 26.9%, p=NS. Globally, there was no significant difference of the PWVAo values between homozygous and heterozygous or negative patients: 9.6±1.53m/sec in TT patients vs 10.36 ±1.79m/sec in GT patients vs 10.10±1.98 m/sec in GG patients(p=NS). There were no significant differences between the values of Aixb, AixAo, PP according to GG vs GT vs TT genotype (generally or per sexes), but homozygous patients (TT) had higher Aixb, PP values, respectively.

Conclusion: In the present study, the presence of the TT homozygote state was not associated with the increase of PWVAo, but seems to determine Aixb and PP increases.
