摘要:

目的 探讨小而密低密度脂蛋白胆固醇(sd-LDL-C)与急性冠状动脉综合征(ACS)的相关性,及其在预测ACS患者远期不良心血管事件发生中的作用。方法 选取接受冠状动脉支架植入治疗的ACS患者149例,其中急性心肌梗死(ACS)32例(AMI组)、不稳定型心绞痛(UAP)117例(UAP组)。另选取健康体检者50名作为正常对照组。检测所有对象的总胆固醇(TC)、三酰甘油(TG)、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)、载脂蛋白(apo)A1、apo B和脂蛋白(a)[Lp(a)],计算非高密度脂蛋白胆固醇(non-HDL-C)。采用Logistic回归分析评估ACS发生的危险因素。对所有患者随访36个月。采用Kaplan-Meier生存曲线评估不同sd-LDL-C水平ACS患者远期不良心血管事件的发生情况。采用Cox回归分析评估不同sd-LDL-C水平ACS患者发生主要心血管不良事件(MACE)和再发ACS的风险。结果 AMI组、UAP组血清TC、TG、LDL-C、non-HDL-C、apo B和sd-LDL-C水平显著高于正常对照组(P<0.05),血清HDL-C水平显著低于正常对照组(P<0.05)。3组之间apo A、Lp(a)差异均无统计学意义(P>0.05)。Logistic回归分析结果显示,sd-LDL-C是ACS发生的危险因素[比值比(OR)=67.184,95%可信区间(CI)为5.284~854.213]。依据ACS患者不良预后的发生情况绘制受试者工作特征(ROC)曲线,基于sd-LDL-C最佳临界值(1.145 mmol/L)将所有ACS患者分为低sd-LDL-C组和高sd-LDL-C组。Kaplan-Meier生存曲线分析结果显示,高sd-LDL-C组远期不良心血管事件发生率高于低sd-LDL-C组(P<0.05)。Cox回归分析结果显示,高sd-LDL-C组患者发生总远期不良心血管事件、MACE和再发ACS的风险显著升高(HR值分别为4.376、3.848、4.067,95%CI分别为2.178~8.791、2.419~6.120、2.002~8.262)。结论 sd-LDL-C在ACS的早期预防和远期预后评估中均有重要的临床价值。

Abstract:

Objective To investigate the correlation between small and dense low-density lipoprotein cholesterol(sd-LDL-C) and acute coronary syndrome(ACS) with long-term adverse cardiovascular events in ACS patients. Methods Totally,149 ACS patients who received coronary artery stent implantation treatment were enrolled,which included 32 cases of acute myocardial infarction(AMI)(AMI group) and 117 cases of unstable angina pectoris(UAP)(UAP group). Totally,50 healthy subjects were enrolled as control group. Total cholesterol(TC),triglyceride(TG),low-density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol(HDL-C),apolipoprotein(apo) A1,apo B and lipoprotein(a)[Lp(a)] were determined,and non-high-density lipoprotein cholesterol(non-HDL-C) was calculated. Logistic regression analysis was used to evaluate the risk factors for the occurrence of ACS. All the patients were followed up for 36 months. Kaplan-Meier survival curve was used to evaluate the incidence of long-term adverse cardiovascular events in ACS patients with different levels of sd-LDL-C. Cox regression analysis was used to evaluate the risk of major adverse cardiovascular events(MACE) and recurrent ACS in ACS patients with different levels of sd-LDL-C. Results The levels of serum TC,TG,LDL-C,non-HDL-C,apo B and sd-LDL-C in AMI and UAP groups were higher than those in control group(P<0.05),while the levels of serum HDL-C were lower than those in control group(P<0.05). There was no statistical significance in apo A and Lp(a) among the 3 groups(P>0.05). The results of Logistic regression analysis showed that sd-LDL-C was a risk factor for the occurrence of ACS [odds ratio(OR)=67.184,95% confidence interval(CI)5.284-854.213]. Based on the occurrence of adverse prognosis in ACS patients,receiver operating characteristic(ROC) curve was drawn,and all the ACS patients were classified into 2 groups,low sd-LDL-C group and high sd-LDL-C group,with the optimal cut-off value of 1.145 mmol/L. Kaplan-Meier survival curve showed that patients with high sd-LDL-C levels had a higher incidence of long-term adverse cardiovascular events compared to patients with low sd-LDL-C levels(P<0.05). Cox regression analysis indicated that an increasing in sd-LDL-C had independent prognostic value for adverse cardiovascular events(total long-term adverse cardiovascular events:HR=4.376,95%CI 2.178-8.791;MACE:HR=3.848,95%CI 2.419-6.120;recurrent ACS:HR=4.067,95%CI 2.002-8.262). Conclusions The sd-LDL-C has clinical value in early prevention and long-term prognosis evaluation of ACS.
