摘要:

目的 探讨血清低密度脂蛋白胆固醇(LDL-C)、超敏C反应蛋白(hs-CRP)联合颈动脉超声参数在疑似冠心病患者中的诊断价值。 方法 纳入2022年8月至2024年8月就诊于南京中医药大学武进附属医院心内科疑似冠心病接受冠状动脉造影(CAG)的患者,共260例。结合CAG,把患者分为非冠心病组(n = 110)和冠心病组(n = 150)例。比较两组患者一般资料和血清LDL-C、hs-CRP及颈动脉超声参数[包括颈动脉内膜中层厚度(CIMT)和颈动脉斑块Crouse积分]。采用Spearman 相关法和多因素logistic回归分析血清LDL-C、hs-CRP及颈动脉超声参数与冠心病的相关性。采用受试者工作特征(ROC)曲线分析血清LDL-C、hs-CRP和颈动脉超声参数单独及联合评估疑似冠心病的预测价值。 结果 (1)冠心病组在年龄、吸烟、空腹血糖(FPG)、收缩压(SBP)、舒张压(DBP)、高血压和糖尿病病史方面高于非冠心病组,差异有统计学意义(P < 0.05)。性别占比、饮酒、体质量指数(BMI)差异无统计学意义(P > 0.05)。(2)冠心病组总胆固醇(TC)、LDL-C、hs-CRP及颈动脉超声参数高于非冠心病组,差异有统计学意义(P < 0.05)。(3)Spearman 相关法和多因素logistic回归分析显示,血清LDL-C、hs-CRP及颈动脉超声参数与冠心病呈正相关(P < 0.05)。(4)ROC曲线分析显示,血清LDL-C、hs-CRP及颈动脉超声参数联合评估的曲线下面积(AUC)、灵敏度和特异度最高,与单独评估相比差异有统计学意义(P < 0.05)。 结论 血清LDL-C、hs-CRP和颈动脉超声参数单独或联合评估是否冠心病均有一定预测价值,联合评估的预测价值更高,对疑似冠心病患者的诊治策略选择有一定指导意义。

Abstract:

Objective To investigate the predictive value of serum low-density lipoprotein cholesterol(LDL-C) and high-sensitive C-reactive protein(hs-CRP) in combination with carotid ultrasound parameters for assessing the risk of coronary heart disease(CHD)in patients with suspected cases. Methods A total of 260 patients who underwent coronary angiography(CAG) in the Department of Cardiology at Wujin Affiliated Hospital of Nanjing University of Traditional Chinese Medicine from August 2022 to August 2024 due to suspected CHD were enrolled in this study. Based on CAG results, patients were categorized into a non-CHD group(n = 110) and a CHD group(n = 150). General clinical characteristics, serum LDL-C, hs-CRP levels, and carotid ultrasound arameters-including carotid intima-media thickness (CIMT) and Crouse score of carotid artery plaque-were compared between the two groups. Spearman correlation analysis and multivariate logistic regression analysis were conducted to evaluate the associations among these parameters. The predictive value of individual and combined markers for suspected CHD was assessed by using receiver operating characteristic(ROC) curve analysis. Results (1)The coronary heart disease(CHD) group had higher age, smoking,fasting plasma glucose(FPG), and blood pressure compared to the non-CHD group(P > 0.05). No significant difference was observed in the gender ratio, alcohol consumption rates, and body mass index(BMI), between the two groups(P > 0.05). (2) Total cholesterol(TC), LDL-C, hs-CRP levels, and carotid ultrasound parameters were significantly higher in the CHD group than those in the non-CHD group (P < 0.05). (3) Spearman correlation analysis and multivariate logistic regression analysis revealed that serum LDL-C,hs-CRP,and carotid ultrasound parameters were significantly correlated with coronary heart disease(P < 0.05). (4) ROC curve analysis demonstrated that the combined assessment of serum LDL-C, hs-CRP, and carotid ultrasound parameters achieved the highest area under the curve (AUC), sensitivity, and specificity, with statistically significant differences compared to individual markers(P < 0.05). Conclusions Serum LDL-C,hs-CRP,and carotid ultrasound parameters individually have predictive value for coronary heart disease, while their combined assessment offers superior predictive accuracy. The enhanced diagnostic performance of the combined valuation provides valuable guidance for the diagnosis and management of patients with suspected coronary heart disease.
