摘要: 背景 残余胆固醇(RC)被认为是评估动脉粥样硬化性心血管疾病(ASCVD)风险的重要指标,且已有研究证实冠状动脉内易损斑块会对ASCVD患者的临床预后产生不利影响,然而关于RC与冠状动脉内易损斑块特征的相关性研究较少。目的 探究RC与急性冠脉综合征(ACS)患者冠状动脉内易损斑块特征的相关性。方法 选取河北省人民医院2017年1月—2021年10月收治的接受经皮冠状动脉介入治疗(PCI)及光学相干断层成像(OCT)检查的ACS患者142例作为研究对象。收集患者的基线资料,采用OCT技术分析患者冠状动脉内斑块特征,根据OCT检查结果有无薄纤维帽粥样硬化斑块(TCFA)将患者分为TCFA组(25例)和无TCFA组(117例)。采用多因素Logistic回归分析探究ACS患者冠状动脉内TCFA的影响因素;绘制受试者工作特征(ROC)曲线评估RC对TCFA的预测价值;采用Spearman秩相关分析RC与冠状动脉斑块特征的相关性。结果 TCFA组患者糖尿病史比例、RC水平高于无TCFA组(P<0.05)。多因素Logistic回归分析结果显示,高RC水平〔OR=5.241,95%CI(1.195,22.995),P=0.028〕是ACS患者冠状动脉内TCFA的危险因素。RC预测ACS患者冠状动脉内TCFA的ROC曲线下面积(AUC)为0.689〔95%CI(0.579,0.798),P=0.003〕,最佳截断值为0.475 mmol/L,灵敏度、特异度分别为76.0%和65.0%。Spearman秩相关分析结果显示,RC与斑块破裂、TCFA、巨噬细胞浸润呈正相关(rs=0.213、0.249、0.186,P<0.05)。结论 RC水平升高可能是ACS患者冠状动脉内TCFA的危险因素,对ACS患者斑块易损性有一定的预测价值,并与冠状动脉内的炎症进展有关。

Abstract: Background Remnant cholesterol (RC) is considered an important indicator to assess the risk of atherosclerotic cardiovascular disease (ASCVD), and the adverse effects of vulnerable plaque on the clinical prognosis of ASCVD patients has been demonstrated, however, there are few studies on the correlation between RC and vulnerable plaque characteristics.Objective To investigate the correlation between RC and vulnerable plaque characteristics in patients with acute coronary syndrome (ACS) .Methods One hundred and forth-two ACS patients admitted to Hebei general hospital who underwent percutaneous coronary intervention (PCI) and optical coherence tomography (OCT) from January 2017 to October 2021 were selected as the study subjects. The baseline data of the patients were collected, the characteristics of intracoronary plaques were analyzed by OCT, and the patients were divided into the TCFA group (25 cases) and the non-TCFA group (117 cases) according to the presence or absence of thin-cap fibroatheroma (TCFA) in OCT results. Multivariate Logistic regression was used to analyze the influencing factors of intracoronary TCFA in ACS patients. The receiver operating characteristic (ROC) curve was plotted to assess the predictive value of RC on TCFA; Spearman rank correlation was used to analyze the correlation between RC and intracoronary plaques characteristics.Results The proportion of patients with diabetes history and RC level in the TCFA group were higher than those in the non-TCFA group (P<0.05). The results of multivariate Logistic regression analysis showed that high RC level〔OR=5.241, 95%CI (1.195, 22.995), P=0.028〕was a risk factor for TCFA in ACS patients. The area under the ROC curve (AUC) of RC to predict intracoronary TCFA in patients with ACS was 0.689〔95%CI (0.579, 0.798), P=0.003〕, with an optimal cut-off value of 0.475 mmol/L, sensitivity and specificity of 76.0% and 65.0%, respectively. The results of Spearman rank correlation analysis showed that RC was positively correlated with plaque rupture, TCFA, and macrophage infiltration (rs=0.213, 0.249, 0.186; P<0.05) .Conclusion Elevated RC level may be a risk factor for TCFA, which has a certain predictive value for plaque vulnerability in ACS patients and is associated with the progression of intracoronary inflammation.
