摘要
为了观察急性冠状动脉综合征患者血清屏氧酶 1活性变化 ,探讨血清屏氧酶 1活性变化在急性冠状动脉综合征中的作用 ,以苯乙酸作为屏氧酶 1的底物 ,采用分光光度法测定 6 0例急性冠状动脉综合征者、32例稳定性冠心病和 2 4例正常健康者血清屏氧酶 1活性。结果表明 ,正常对照组血清屏氧酶 1活性为 136± 6 4μmol (L·min) ,急性心肌梗死组为 95± 42 μmol (L·min) ,不稳定心绞痛组为 80± 36 μmol (L·min) ,均显著降低 (P <0 .0 5 ) ;稳定性冠心病组 [133± 2 9μmol (L·min) ]与正常对照组无差异。血清屏氧酶 1活性与甘油三酯 (r=0 .496 ,P =0 .0 0 1)及载脂蛋白B(r=0 .34 2 ,P =0 .0 0 2 )呈正相关 ,与高密度脂蛋白胆固醇无相关性。结果提示急性冠状动脉综合征患者血清屏氧酶 1活性降低 ,推测抗氧化能力下降可能参与该综合征的发病过程
