【目的】探讨脂蛋白 (a) [Lp (a) ]联合最大颈动脉内膜中层厚度 (CIMT) 与冠心病血瘀证的关系,并评估其预测价值。【方法】选取2023年1月至2024年1月于广东省中医院大德路医院心血管科住院治疗的冠心病患者207例,根据《冠心病血瘀证诊断标准》分为血瘀证组110例和非血瘀证组97例。收集患者冠状动脉造影前的Lp (a) 、CIMT、糖化血红蛋白 (HbA1c)等临床资料,采用多因素 Logistic 回归分析探讨冠心病患者血瘀证的独立危险因素,并采用受试者工作特征 (ROC) 曲线分析各指标独立及多指标联合的预测效能。 【结果】(1) 单因素分析结果显示:血瘀证组患者的饮酒史、高血压、糖尿病及HbA1c、Lp (a) 、最大CIMT水平均高于非血瘀证组 (P<0.05或P<0.01) 。 (2) 多因素 Logistic 回归分析结果显示:Lp (a) [OR=1.004,95%CI (1.002~1.005) ]、最大CIMT水平升高[OR=10.999,95%CI (1.897~63.784) ]以及具有高血压病史[OR=2.354,95%CI (1.141~4.856) ]是冠心病血瘀证的独立危险因素 (P<0.05或P<0.01) 。 (3) ROC 曲线分析结果显示:Lp (a) 、最大CIMT、Lp (a) 联合最大CIMT模型、Lp (a) +最大CIMT联合高血压模型预测冠心病血瘀证的 ROC 曲线下面积 (AUC) 分别为 0.749、0.650、0.773、0.787 (P<0.001) ,其中两个联合诊断模型的灵敏度分别为0.655、0.736,特异度分别为0.804、0.742。 【结论】Lp (a) 和最大CIMT联合检测能提高冠心病血瘀证的预测效能,可为临床识别冠心病血瘀证患者提供依据。

Objective To investigate the correlation between lipoprotein(a)[Lp(a) ] combined with maximum carotid intima-media thickness (CIMT) and coronary heart disease with blood stasis syndrome,and to assess its predictive value. Methods A total of 207 patients with coronary heart disease who were hospitalized in the Cardiovascular Department of Guangdong Provincial Hospital of Chinese Medicine(Dade Road Hospital) from January 2023 to January 2024 were selected. According to the Diagnostic Criteria for Blood Stasis Syndrome of Coronary Heart Disease,the patients were divided into the blood stasis syndrome group (110 cases) and the non-blood stasis syndrome group (97 cases) . Before coronary angiography,the clinical data such as Lp (a) ,CIMT and glycosylated hemoglobin (HbA1c) of the patients were collected. Multivariate Logistic regression analysis was conducted to explore the independent risk factors of blood stasis syndrome in the patients with coronary heart disease,and the receiver operating characteristic (ROC) curve was drawn for the analysis of the predictive efficacy of the indicators, independently and jointly. Results (1) The results of univariate analysis showed that the percentages of the patients having drinking history, hypertension history, and diabetes in the blood stasis syndrome group and the levels of HbA1c,Lp (a) ,and maximum CIMT were higher when compared with those in the non-blood stasis syndrome group (P<0.05 or P<0.01) . (2) The results of multivariate Logistic regression analysis showed that Lp (a) [OR=1.004,95%CI (1.002-1.005) ],increased level of maximum CIMT [OR=10.999,95%CI (1.897-63.784) ],and history of hypertension [OR=2.354,95%CI (1.141-4.856) ] were independent risk factors for blood stasis syndrome in the patients with coronary heart disease (P<0.05 or P<0.01) . (3) The results of ROC curve analysis showed that the area under the curve (AUC) of ROC for the prediction of blood stasis syndrome in the patients with coronary heart disease by Lp (a) ,maximum CIMT,Lp (a) combined with maximum CIMT model,Lp (a) + maximum CIMT combined with hypertension model were 0.749,0.650,0.773,and 0.787,respectively (P<0.001),and the sensitivity of the two combined diagnostic models was 0.655 and 0.736,and their specificity was 0.804 and 0.742,respectively. Conclusion The combined detection of Lp(a) and maximum CIMT can enhance the predictive efficacy of blood stasis syndrome in the patients with coronary heart disease,and will provide evidence for the clinical identification of blood stasis syndrome in the patients with coronary heart disease.
