A common NOS3 polymorphism (the gene which encodes endothelial nitric oxide synthase), a variable number of tandem repeats within Intron 4 has been associated with cardiovascular disorders in which nitric oxide bioactivity is impaired including myocardial infraction. Consistent characteristic changes in the pressure pulse wave shape have been associated with ageing, risk factors for cardiovascular disease and impaired NO bioactivity. Therefore pulse waveform analysis can be ut...

We hypothesised that SNPs within oxidative stress genes influence vascular compliance in patients with coronary artery disease.A SNP within the gene encoding the eNOS (NOS3) which encodes a Glu298→Asp amino acid substitution has been associated with cardiovascular disorders in which NO bioactivity is impaired. The gene coding for p22phox, a critical component of the NADH/NAD(P)H oxidase enzyme system, a major source of vascular SO, is CYB...
