Abstract

ABSTRACT: Several recent studies showed that C825T polymorphism is related to cardiovascular diseases in normal population. However, studies on whether 825T allele influences the incidence of cardiovascular diseases in hypertensive patients are rare. 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. Established cardiovascular risk factors were used to adjust the multivariate Cox analysis. After a mean follow-up period of 7.60 ± 1.12 years, a significantly higher incidence of MACEs was seen in the TT genotype group than CC and CT genotypes. The TT variant was significantly and independently predictive of MACEs ( relative risk = 2.574; p < 0.001), CAD ( relative risk = 2.963; p < 0.001), but not stroke, CAD+stroke or death. The GNB3 TT genotype is a risk factor for CAD independent of other established cardiovascular risk factors in Chinese hypertensive patients.
