摘要：

目的探讨红细胞膜胆固醇水平是否与非ST抬高型急性冠状动脉综合征(ACS)患者经皮冠状动脉介入治疗(PCI)相关慢血流或无复流发生密切相关,或许是冠状动脉慢血流或无复流的预测因子。方法选取我院2012年3月至2014年3月收治的295例非ST抬高型ACS患者作为研究对象,年龄57.54±12.16岁,男168例,女127例。应用酶学方法检测红细胞膜胆固醇等生化因子。所有患者术前进行Gensini及Syntax评分后进行标准的冠状动脉造影并行罪犯血管PCI术,术后即刻应用TIMI血流计帧法评估冠状动脉血流速度,并分为血流正常组和慢血流或无复流组。结果与冠状动脉血流正常患者相比,发生PCI相关冠状动脉慢血流或无复流患者红细胞膜胆固醇水平明显升高(142.05±26.37比95.46±22.58,P<0.001)。此外,发生慢血流或无复流患者的罪犯相关血管狭窄程度、Gensini积分、Syntax评分、支架长度及数量、中性粒细胞计数及高敏C反应蛋白(hs-CRP)均显著增加(P<0.001)。同时发现吸烟和高龄与冠状动脉慢血流或无复流发生密切相关(P<0.05)。而低密度脂蛋白胆固醇(LDLC)、高密度脂蛋白胆固醇(HDLC)及总胆固醇(TC)水平在两组间未见明显差异(P>0.05)。多因素Logistic回归分析发现,红细胞膜胆固醇水平与罪犯血管狭窄程度、Gensini积分、Syntax积分、hs-CRP及长期吸烟史密切相关(OR分别为0.81、0.609、0.327、5.16及3.17,P<0.01),而与总胆固醇水平、LDLC、HDLC无明显相关(OR分别为1.21、1.19及1.08,P>0.05)。结论红细胞膜胆固醇水平与非ST抬高型ACS患者PCI相关冠状动脉慢血流或无复流发生密切相关,是非ST抬高型ACS患者PCI相关冠状动脉慢血流或无复流发生的预测因子,其机制与增加斑块内脂质核体积和PCI术中脂质核内含物释放及炎症激活有关。
