Association between rs1049673 polymorphism in CD36 and premature coronary heart disease.

Risk factors for premature coronary heart disease in China can be multiple; we investigated Chinese Han patients with premature coronary heart disease and a possible association with CD36 polymorphism at rs1049673, rs7755, and rs321159 sites. Outpatients were recruited according to chest X-ray coronary arteriography results; they were divided into two groups: early coronary artery lesions (premature coronary heart disease group, test group) and a control group. Coronary arteriography and laboratory blood examinations were conducted to analyze risk factors for coronary heart disease and CD36 polymorphisms. Seventy nine test and 56 control group patients were recruited. Compared with the control, the test groups had a significantly higher proportion of male patients, smoking, diabetes and metabolic syndromes, significantly higher levels of TG, LDL-C, ox-LDL, WBC, UA, FBG, and significantly lower levels of HDL-C. For rs1049673, rs7755, and rs321159 sites, patients with premature coronary heart disease have family genetic predisposition at high LDL-C level with GA, AA, and TT genotypes. Unconditional logistic regression analysis showed that gender, diabetes, high TG, LDL-C level and C carriers of rs1049673 significantly affected risk for premature coronary heart disease.
