ApoE基因多态性与冠心病患者冠状动脉病变的相关性研究

ApoE基因多态性与冠心病患者冠状动脉病变的相关性研究摘要：目的：研究ApoE基因多态性与冠心病患者冠状动脉病变的相关性。方法：采集200名冠心病患者的血液样本并分离DNA，采用PCR技术进行ApoE基因多态性分型，并依据冠状动脉造影结果分为冠状动脉病变组和非病变组。比较两组ApoE基因型分布的差异。结果：在200名冠心病患者中，ε3/ε3基因型最为常见，占68.5%；病变组中ε4等位基因频率显著高于非病变组（P<0.05）；而ε2等位基因频率病变组低于非病变组（P<0.05）。结论：ApoE基因ε4等位基因与冠心病患者冠状动脉病变相关，而ε2等位基因可能具有保护作用。

Abstract:

Objective:ToinvestigatethecorrelationbetweenApoEgenepolymorphismandcoronaryarterydiseaseinpatientswithcoronaryheartdisease.Methods:Bloodsampleswerecollectedfrom200patientswithcoronaryheartdiseaseandDNAwasisolated.ApoEgenepolymorphismwasanalyzedbyPCRtechnique,andthepatientsweredividedintocoronaryarterydiseasegroupandnon-diseasegroupbasedoncoronaryarteriographyresults.ThedifferenceinApoEgenotypedistributionbetweenthetwogroupswascompared.Results:Amongthe200patientswithcoronaryheartdisease,theε3/ε3genotypewasthemostcommon,accountingfor68.5%.Thefrequencyoftheε4allelewassignificantlyhigherinthediseasegroupthaninthenon-diseasegroup(P<0.05),whilethefrequencyoftheε2allelewaslowerinthediseasegroupthaninthenon-diseasegroup(P<0.05).Conclusion:TheApoEε4alleleisassociatedwithcoronaryarterydiseaseinpatientswithcoronaryheartdisease,whiletheε2allelemayhaveaprotectiveeffect.
