Abstract:
BACKGROUNDSequence variants in the β-adrenergic receptor (ADRB) genes have a close relationship with the development of coronary artery disease (CAD) and the patient's prognosis. However, there is a lack of data on the role of the variants in ADRBs genes in Han Chinese patients with CAD. We aimed to investigate the association of genetic variants in the ADRB1 and ADRB2 genes with the incidence of major adverse cardiac event (MACE) in Han Chinese patients with CAD.
METHODSA total of 545 Han Chinese patients with CAD undergoing percutaneous coronary intervention (PCI) were recruited to the study and followed for one year. Three variant sites in ADRB1 (rs1801253) and ADRB2 (rs1042713 and rs1042714) were genotyped. The effect of the ADRB1 and ADRB2 genotypes on MACE within one year was assessed.
RESULTSThere were 47 cases of MACE during follow-up. There was no significant difference in the incidence of MACE among patients carrying different genotypes of the three variants in ADRB1 and ADRB2 (Log-rank, all P > 0.05). Cox regression analysis showed no association between three variants in ADRB1 and ADRB2 genes and the incidence of MACE during one-year follow-up, the adjusted hazard ratios (95% confidence interval) for rs1801253, rs1042713 and rs1042714 were 1.05 (0.54-2.02), 1.24 (0.58-2.64) and 1.66 (0.81-3.42), respectively.
CONCLUSIONOur data did not support a relationship between the three polymorphisms of ADRB1 (rs1801253) and ADRB2 (rs1042713 and rs1042714) genes and risk of subsequent cardiovascular events after PCI in Han Chinese patients with CAD.
