摘 要:目的 探讨血清炎性因子高敏C反应蛋白(hs-CRP)、脂蛋白相关磷脂酶A2(Lp-PLA2)水平与冠状动脉罪犯病变纤维脂质斑块纤维帽厚度之间的相关性.方法 入选2015年1月至2016年1月在南京医科大学附属南京医院择期行冠状动脉造影的冠心病患者117例,对其临床资料进行回顾性分析.根据冠心病的类型,将患者分为稳定性心绞痛(SAP)组(47例)、不稳定性心绞痛(UAP)组(52例)和急性非ST段抬高型心肌梗死(NSTEMI)组(18例).检测患者术前血清hs-CRP及Lp-PLA2水平,术中在介入治疗前使用光学相干断层成像(OCT)观察罪犯病变斑块性质,并分析血清hs-CRP及Lp-PLA2水平与纤维脂质斑块纤维帽厚度之间的关系.结果 (1)NSTEMI组术前血清hs-CRP[2.13(1.04,4.75) μg/L比1.02(0.60,1.29) μg/L和1.30(1.03,1.96) μg/L,P均〈0.05]和Lp-PLA2[(394.8 ±61.4)mg/L比(140.1±40.4) mg/L和(284.5±93.6) mg/L,P均〈0.05]水平均高于SAP组和UAP组,UAP组术前血清hs-CRP和Lp-PLA2水平均高于SAP组(P均〈0.05).(2) NSTEMI组和UAP组的罪犯病变纤维脂质斑块纤维帽厚度均小于SAP组[50(50,60) μm和60(50,90) μm比130(80,190) μm,P均〈0.05],NSTEMI组与UAP组之间的罪犯病变纤维脂质斑块纤维帽厚度差异无统计学意义(P〉0.05).NSTEMI组薄纤维帽粥样斑块[82.35%(14/18)比19.15%(9/47)和63.46%(33/52),P均〈0.05]、斑块破裂[55.56% (10/18)比6.38%(3/47)和28.85%(15/52),P均〈0.05]和血栓形成[33.33%(6/18)比4.26% (2/47)和9.26%(5/52),P均〈0.05]的比率均高于SAP组和UAP组;NSTEMI组斑块内钙化的比率低于SAP组[11.11%(2/18)比42.55%(20/47),P〈0.05],与UAP组[19.23%(10/52)]之间差异无统计学意义(P〉0.05).(3) Pearson相关分析显示,术前血清hs-CRP(r=-0.233,P〈0.05)和Lp-PLA2(r=-0.465,P〈0.01)水平与纤维脂质斑块纤维帽厚度均呈负相�Objective To identify the correlation between serum inflammatory cytokine levels including high sensitive C reactive protein (hs-CRP) and lipoprotein associated phospholipase (Lp-PLA2) and the fibrous cap thickness of fibrofatty plaque in coronary culprit lesions.Methods Clinical data of 117 patients with selective coronary artery angiography diagnosed coronary artery disease admitted to our hospital from January 2015 to January 2016 were retrospective analyzed.According to type of coronary disease,patients were divided into 3 subgroups:SAP group (containing 47 stable angina patients),UAP group (containing 52 unstable angina patients),and NSTEMI group(containing 18 acute non ST segment elevation myocardial infarction patients).Serum hs-CRP and Lp-PLA2 levels were measured before subsequent procedures.The characteristics of the culprit lesions were detected by optical coherence tomogarpgy (OCT) before interventional treatment,and the correlation between hs-CRP and Lp-PLA2 and the fibrous cap thickness of fibrofatty plaque in coronary culprit lesions were analyzed.Results (1) The serum levels of hs-CRP (2.13 (1.04,4.75) μg/L vs.1.02 (0.60,1.29) μg/L and 1.30 (1.03,1.96) μg/L,all P 〈 0.05)and Lp-PLA2 ((394.8 ± 61.4) mg/L vs.(140.1 ± 40.4) mg/L and (284.5 ± 93.6) mg/L,all P 〈 0.05)were significantly higher in NSTEMI group than in SAP group and UAP group,and serum levels of hs-CRP and Lp-PLA2 were significantly higher in UAP group than in SAP group (all P 〈 0.05).(2) The fibrous cap thickness of fibrofatty plaque in coronary culprit lesions were smaller in NSTEMI group and UAP group than in SAP group(50(50,60) μm and 60(50,90) μm vs.130(80,190) μm,all P 〈0.05),and there was no significantly difference between NSTEMI group and UAP group (P 〉 0.05).Proportion of thin-cap fibroatheroma plaque (82.35 % (14/18) vs.19.15 % (9/47) and 63.46% (33/52),all P 〈 0.05),plaque rupture(55.56% (10/18) v
