摘要

Objective: To assess the relationship between apolipoprotein E(apoE) polymorphism and early onset of Coronary heart disease (CHD) and the effect of apoE on lipids and lipoproteins in Chinese healthy subjects. Methods: Sixty-eight cases (CHD1) aged less than 55 y, 136 cases (CHD2) aged mare than 65 y with CHD and 136 healthy subjects were enrolled and their plasma levels of triglyceride(TG), total cholesterol(TC) and high density lipoprotein cholesterol (HDL-C) were determined. The apoE genotypes were identified by polymerase chain reaction-restriction fragment lengths polymorphism. Results: apoE3/ 4 genotype and E4 allele frequency in CHD1 were higher than those in CHD2 and healthy subjects and no difference was found between CHD2 and healthy subjects. Meanwhile the plasma levels of TC and low density lipoprotein cholesterol(LDL-C) were higher in CHD2 than in either CHD1 or healthy subjects. Each apoE isoprotein has variable TC and LDL-C levels characterized by E2 (E2/2 + E2/3)
