摘要 目的分析血小板源性生长因子D(PDGF-D)基因多态性与冠状动脉粥样硬化斑块稳定性的关系。方法疑诊冠心病患者349例,其中经冠脉动脉造影确诊冠心病237例(观察组)、排除冠心病112例(对照组),观察组确诊后行血管内超声检查判断斑块稳定性,两组均采用聚合酶链反应-限制性片段长度多态性方法检测PDGFD rs7950273位点基因型。结果观察组rs7950273位点CC、GG基因型频率分别为26.2%、18.1%,C等位基因频率为54.1%;对照组分别为14.2%、34.8%、39.7%,P均<0.05。观察组易损斑块者CC基因型、C等位基因频率分别为31.5%、57.9%,混合斑块者分别为31.3%、58.4%,均高于稳定斑块者的12.3%、43.1%(P均<0.05),易损斑块与混合斑块者比较P均>0.05。结论冠状动脉粥样硬化斑块越不稳定,PDGF-D rs7950273位点CC基因型频率和C等位基因频率越高;PDGF-D rs7950273位点C等位基因可能是冠状动脉粥样硬化斑块不稳定的遗传易感基因。
