摘要 为观察青年人 (<4 0岁 )急性心肌梗死血清晚期糖基化终末产物—Nε 羧甲基赖氨酸含量的变化 ,探讨其发病机制。采用抗戚蓝蛋白晚期糖基化终末产物抗体竞争酶联免疫吸附测定法测定 32例青年人急性心肌梗死、4 7例中老年人急性心肌梗死和 38例健康年轻自愿者血清中Nε 羧甲基赖氨酸含量。结果发现 ,年轻对照组中有 5例血清Nε 羧甲基赖氨酸含量 >0 .1mg L ,青年人急性心肌梗死组有 14例 ,两组差异显著 (P <0 .0 5 ) ,其中冠状动脉单支病变组与多支病变组相比具有显著性差异 (P <0 .0 5 ) ;但中老年人急性心肌梗死组Nε 羧甲基赖氨酸水平较青年人急性心肌梗死组显著增加 (P <0 .0 0 1) ,冠状动脉单支病变与多支病变相比具有显著性差异 (P <0 .0 5 )。中老年人急性心肌梗死中合并糖尿病患者与不合并糖尿病患者血清Nε 羧甲基赖氨酸水平无显著性差异 (P >0 .0 5 )。结果提示 ,机体内晚期糖基化终末产物的产生增多部分参与了青年人冠状动脉粥样硬化的形成和急性心肌梗死的发病机制。
