摘要：Objective To describe the association between apolipoprotein E alleles, dyslipidemia, and coronary heart disease (CHD). Methods Using polymerase chain reaction (PCR) the restriction fragment length polymorphism (RFLP), we studied the apolipoprotein E genotypes in 142 patients with coronary artery disease (CAD) and 131 age-matched healthy subjects, as well as the association between apolipoprotein, plasma lipids, and CHD. Results Compared with the E3 allele, the E4 allele was associated with elevated total cholesterol (TC) values (average increase about 0.32-0.58 mmol/L), low-density lipoprotein cholesterol (LDL-C) values, and apolipoprotein B (APOB). The E2 allele has opposite effects (average decrease about 0.34-0.61 mmol/L at TC). Both in cases and controls, the allelic frequency of E3/3 was highest, reaching 67.8% of whole volume, hemozygote of apo E3 was moderate, and homozygote E4/4 was low, E2/2 and E4/2 were rare. The frequencies of E3/4 and E4/4 were significantly higher in patients with CAD compared with controls (P<0.001).Conclusion Apolipoprotein E alleles are important genetic markers for dyslipidemia and CHD.The carrier of E4 gene was the risk factor of CHD.
