摘要
目的 :探讨氧化型低密度脂蛋白 (ox- LDL )自身抗体及其免疫复合物与冠心病之间的关系。方法 :应用酶联免疫法对 6 1例确诊的冠心病患者、116例高血压患者和 12 3例健康对照组进行血清 ox- LDL自身抗体及其循环免疫复合物的检测 ,并同步测定 ox- LDL和血脂水平。结果 :冠心病患者自身抗体 Ig G[2 1.4 8(17.5 8~ 2 9.0 1) ]U/L和 Ig M[4 .71(3.88~ 7.0 6 ) ]U/ L以及 ox- L DL [0 .87(0 .4 4~ 1.0 8) ]mg/ L均显著高于高血压组 [15 .93(11.12~2 2 .2 6 ) U/ L、2 .5 4 (1.17~ 5 .0 5 ) U/ L、0 .32 (0 .16~ 0 .6 1) mg/ L ]和健康对照组 [11.12 (4.70~ 16 .5 7) U/ L、1.6 1(0 .6 0~ 3.0 3) U/ L、0 .2 3(0 .12~ 0 .36 ) mg/ L],P均 <0 .0 0 1,而循环免疫复合物 [2 .6 3(1.6 9~ 5 .90 ) U/ L ]显著低于高血压组 [15 .71(6 .2 5~ 2 8.74 ) U/ L]和健康对照组 [12 .5 4 (8.2 8~ 2 3.90 ) U/ L ],P均 <0 .0 0 1。ox- LDL与其自身抗体之间的关系在各组之间存在不一致性。结论 :ox- LDL自身抗体与循环免疫复合物在冠心病患者中的变化可能与ox- L DL及其自身抗体在冠状动脉硬化进程中发挥作用有关。
