Changes of serum low-density lipoprotein immune complexes in patients with complicated coronary lesion and their implication / 医学研究生学报

ABSTRACT

Objective:To study the significance of low-density lipoprotein immune complexes(LDL-IC) in the pathogenesis of complicated coronary lesion.Methods:Enzyme-linked immunosorbent assay(ELISA) was used to measure the serum LDL-IC in 139 patients with coronary heart disease and 111 normal controls.The patients were divided by coronary angiography into a multi-vessel diseased group,an ambi-vessel diseased group,mono-vessel diseased group;diffuse lesion group,a located lesion group,a serious stenoses group and a light stenoses group.Results: The LDL-IC level was significantly higher in the multi-vessel diseased group than in the ambi-vessel diseased group([2.75?1.22]AU vs [2.35?0.83]AU,P
