Logistic regression analysis indicated that the GNB3 825T allele carriers were positively associated with EH in males (odds ratio (OR) for TT/CT, 1.459; 95% confidence interval (CI), 1.048-2.033, P=0.0255).
In 34 white patients with established mild to moderate essential hypertension (World Health Organization stage I or II, mean age 52 +/- 9 years) genotype analysis of GNB3C825T polymorphism, insertion/deletion polymorphism of the ACE gene and 1166 A/C polymorphism of the AT1 receptor gene was performed.
In the current study, 729 patients (CC, n = 332; CT, n = 313; TT, n = 84) with essential hypertension were genotyped for C825T polymorphism of the GNB3 gene and followed 8 years for major adverse cardiovascular events (MACEs) which include stroke, the onset of coronary artery disease (CAD), and all-cause death.
GNB3 825 C>T is likely to be a significant risk factor for LVH but not for EH in the Emirati population, thereby strengthening the view that LVH is genetically a separate clinical entity.
