摘要:

目的 探讨血浆氧化低密度脂蛋白(ox-LDL)联合高分辨磁共振血管壁成像(HRMR-VWI)高信号特征对急性脑梗死患者动脉粥样硬化斑块稳定性的预测价值。方法 选取急性脑梗死患者147例,根据斑块稳定性分为稳定组(61例)和不稳定组(86例)。收集2组基线资料,HRMR-VWI检查获取斑块特征指标;采用Pearson相关性分析探讨ox-LDL与HRMR-VWI指标的相关性,受试者工作特征(ROC)曲线分析各指标及联合检测对斑块不稳定性的预测效能,多因素Logistic回归分析斑块不稳定性的影响因素。结果 与稳定组相比,不稳定组甘油三酯(TG)、低密度脂蛋白胆固醇(LDL-C)、空腹血糖(FPG)、糖化血红蛋白(HbA1c)、收缩压(SBP)、舒张压(DBP)、脂蛋白相关磷脂酶A2(LP-PLA2)、C-反应蛋白(CRP)、胱抑素C(CysC)、同型半胱氨酸(HCY)、ox-LDL水平显著升高(P<0.05);斑块负荷、斑块内出血、纤维帽破损及大脂质坏死核心比例显著升高(P<0.05)。Spearman相关性分析显示,ox-LDL与斑块负荷(rs=0.174)、斑块内出血(rs=0.241)、纤维帽破损(rs=0.352)呈正相关(P<0.05)。ROC曲线分析显示,ox-LDL、斑块负荷、斑块内出血、纤维帽破损及联合预测斑块不稳定性的曲线下面积(AUC)分别为0.802(95%CI:0.728~0.863)、0.798(95%CI:0.723~0.859)、0.754(95%CI:0.676~0.821)、0.774(95%CI:0.698~0.839)和0.957(95%CI:0.910~0.983),联合预测效能最高。多因素Logistic回归分析显示,ox-LDL(OR=1.137,95%CI:1.070~1.208)、斑块负荷(OR=1.292,95%CI:1.151~1.450)、斑块内出血(OR=2.843,95%CI:2.239~3.611)、纤维帽破损(OR=3.200,95%CI:2.494~4.104)是急性脑梗死患者斑块不稳定性的危险因素(P<0.05)。结论 血浆ox-LDL水平及HRMR-VWI相关指标与脑梗死患者斑块稳定性密切相关,联合检测可显著提高对斑块不稳定性的预测效能。

Abstract:

Objective To explore the predictive value of plasma oxidized low-density lipoprotein (ox-LDL) combined with high-resolution vascular wall imaging (HRMR-VWI) hyperintensity features for the stability of atherosclerotic plaques in patients with cerebral infarction. Methods A total of 147 patients with cerebral infarction were selected and divided into the stable group (n=61) and the unstable group (n=86) based on plaque stability. Baseline data were collected from both groups, and plaque characteristic indicators were obtained through HRMR-VWI examination. Pearson correlation analysis was used to explore the relationship between ox-LDL and HRMR-VWI indicators. ROC curve analysis was conducted to evaluate the predictive efficacy of individual and combined indicators for plaque instability. Multivariate Logistic regression analysis was performed to identify the influencing factors of plaque instability. Results Compared with the stable group, there were significantly increased levels of triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), fasting blood glucose (FPG), glycated hemoglobin (HbA1c), systolic blood pressure (SBP), diastolic blood pressure (DBP), lipoprotein related phospholipase A2 (LP-PLA2), C-reactive protein (CRP), cystatin C (CysC), homocysteine (HCY) and ox-LDL in the unstable group (P<0.05). The plaque burden, incidence of intraplaque hemorrhage, incidence of fibrous cap damage and incidence of large lipid necrosis core were also significantly increased (P<0.05). Spearman correlation analysis showed that ox-LDL was positively correlated with plaque burden (rs=0.174), plaque bleeding (rs=0.241) and fibrous cap damage (rs=0.352) (P<0.05). ROC curve analysis revealed that the AUCs for ox-LDL, plaque burden, intraplaque hemorrhage, fibrous cap rupture and combined prediction were 0.802 (0.728-0.863), 0.798 (0.723-0.859), 0.754 (0.676-0.821), 0.774 (0.698-0.839) and 0.957 (0.910-0.983), respectively, with combined prediction demonstrating the highest efficacy. Multivariate Logistic regression analysis indicated that ox-LDL (OR=1.137,95%CI: 1.070-1.208), plaque burden (OR=1.292, 95%CI: 1.151-1.450), intraplaque hemorrhage (OR=2.843, 95%CI: 2.239-3.611) and fibrous cap rupture (OR=3.200, 95%CI: 2.494-4.104) were risk factors for plaque in stability in patients with cerebral infarction (P<0.05). Conclusion The levels of plasma ox-LDL and related indicators of HRMR-VWI (plaque burden, intraplaque hemorrhage and fibrous cap damage) are closely related to plaque stability in patients with cerebral infarction. Combined detection can significantly improve the predictive efficacy of plaque instability.
