Abstract:
OBJECTIVETo assess the association of haptoglobin (HP)1/2 polymorphism with coronary heart disease (CHD) in Chinese Hans.
METHODSOne hundred and eighty-nine CHD patients and 242 healthy controls confirmed with angiography were recruited. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method was utilized to genotype the HP1 and HP2 alleles and genotype frequencies in cases and controls were compared.
RESULTSThe frequency of HP2-2 genotype was significantly higher in CHDs than in controls (0.54 vs.0.35, P = 0.000). The HP2-2 genotype significantly increased the risk for CHD in univariable analysis (OR = 2.166, 95%CI: 1.467-3.196). Multifactor Logistic regression analysis indicated that HP2-2 genotype is an independent risk factor to CHD (P = 0.002; OR = 2.101, 95%CI: 1.311-3.367). Similarly, the HP2 allele frequency in the CHD group was significantly higher than that in the control subjects (0.74 vs.0.61, P = 0.000).
CONCLUSIONThe HP2-2 genotype is associated with CHD in Chinese. HP2-2 genotype may be an independent risk factor to CHD, and HP2 allele may be a genetic susceptibility factor to CHD in Chinese.
