The two-factor dispersion analysis showed that the 786T>C (rs2070744) polymorphism of the NOS3 gene significantly influenced the ventricular hypertrophy (G9) at simultaneous cumulative impact with the age factor: the “Age” factor on the “Myocardium” index, right and left ventricular repolarization (G5, G6), and their depolarization symmetry (G7). This evidence concerns the gene NOS3 and Ventricular hypertrophy.
