摘 要:目的:探讨低密度脂蛋白免疫复合物(LDL-IC)在急性冠状动脉综合征(ACS)发生发展过程中的作用及其临床意义。方法:采用酶联免疫吸附法测定139例冠心病患者(ACS组76例,非ACS组63例)及111例正常对照组的血清LDL-IC浓度。根据冠状动脉造影结果将冠心病组分为多支病变组(病变≥2支)及单支病变组(1支病变)进行比较。结果:①ACS患者LDL-IC水平显著高于非ACS冠心病患者[(2.78±1.08)AU(相对单位)vs(1.74±0.45)AU,P<0.01]和正常对照组[(2.78±1.08)AUvs(1.55±0.71)AU,P<0.01]。②多支病变组LDL-IC水平高于单支病变组[(2.60±1.10)AUvs(1.82±0.50)AU,P<0.01]及正常对照组[(2.60±1.10)AUvs(1.55±0.71)AU,P<0.01]。③LDL-IC水平与氧化低密度脂蛋白(ox-LDL)水平呈显著正相关(r=0.348,P<0.01)。结论:LDL-IC与ACS的发生发展及冠状动脉病变程度之间可能存在一定的相关性。Objective:To study the significance of LDL immune complexes in the pathogenesis of acute coronary syndrome(ACS). Methods: Enzyme linked immunosorbent Assay was used to measure the plasma LDL-IC in 139 patients with coronary heart disease (76ACS ;63NACS) and in 111 control subjects. The patients with coronary heart disease were divided into multi-vessel diseased group( 2-vessel diseased group and 2 vessels more) and mono-vessel diseased group ( 1-vessel diseased group) by coronary angiography. Results: (1)LDL-IC level was higher in patients with ACS than that in patients with non-ACS [ (2.78 ± 1.08 ) AU vs ( 1.74 ± 0.45 ) AU, P 〈 0.01 ] and than that in control subjects [ ( 2.78 ± 1.08)AU vs (1.55 ± 0.71 )AU,P 〈 0.01 ]. (2)LDL-IC level was higher in patients with multi-vessel diseased group than that in mono-vessel diseased group[ (2.60 ± 1.10)AU vs ( 1.82 ±0.50) AU,P 〈 0.01 ] and than that in control subjetcs [ (2.60 ± 1.10) AU vs ( 1.55 ± 0.71 ) AU, P 〈 0.01 ]. (3)LDL-IC level was correlated with ox-LDL( r = 0.348, P 〈 0.01 ). Conclusion :LDL-IC might have some relation to the pathogenesis of ACS and the severity of coronary lesions.
