Many researches have been published pertaining the influence of ApoE gene polymorphism on coronary artery disease, dyslipidemia and the response of statin in Han Chinese. Most of the studies in Han Chinese like other populations demonstrated that ApoE 4 allele genetically predisposes coronary artery disease, acute coronary syndrome, severity of occlusion of coronary artery and higher incidence of major adverse cardiovascular events (In Han Chinese, ApoE allele carriers demonstrated 85% increase in major adverse cardiovascular events (MACE) in six months follow up). In addition, ApoE4 allele carrier also showed both increased in LDL level and decrease response to statin therapy in dyslipidemic Han Chinese. On the other hand, ApoE2 carrier is scavenger of cholesterol and triglyceride from the blood;?thus it is cardiovascular-protective. Despite positive relationship between ApoE gene polymorphism and cardiovascular pathologies, prognostic outcome and resistance to intervention, this area of research still requires?extensive investigation in Han Chinese. Because, several other studies revealed either negative effect or showed no effect by ApoE gene polymorphism on cardiovascular disease. Some of the causes of such debatable results could be explained by factors such as diminutive frequency allele and expression of ApoE gene in coronary heart disease. This part of the research yet requires extensive study with bulkier sample size and retrospective in nature, in order to ascertain the influence of ApoE genotype on lipid, anti-hyperlipidemic agent and coronary heart disease. Such studies could assist us to confirm whether to test healthier subjects to predict genetic risk of coronary heart disease in Han Chinese population. The aim of this review paper is to critically analyze the effect of ApoE gene on the occurrence of coronary heart disease in Han Chinese.展开更多
