摘要：

目的　探讨血浆同型半胱氨酸 (HCY)与冠心病 (CHD)的相关性、与CHD传统危险因素的关系及其致CHD的机制。方法　分别测定CHD患者 (10 5例 )及对照组 (32例 )血中HCY、内皮素(ET)、一氧化氮 (NO)、一氧化氮合酶 (NOS)水平及血脂各参数。结果　CHD组高同型半胱氨酸血症(HHCY)的发生率明显高于对照组 (49 5 %比 9 4 % ,P <0 0 1) ,CHD组HCY水平明显高于对照组[(15 2 9± 5 14 ) μmol L比 (10 6 6± 2 78) μmol L ,P <0 0 1]。多元回归分析显示HCY对CHD的相对危险度 (RR)为 1 397(95 %可信区间 :1 137～ 1 6 4 5 ,P <0 0 1) ,表明HCY为CHD的独立危险因素。HCY与年龄、甘油三酯有关 (P <0 0 5 )。HCY与ET呈正相关 (P <0 0 1) ,而与NO、NOS呈负相关 (P <0 0 1)。结论　HHCY是CHD的独立危险因素。HCY可能损伤血管内皮细胞 ,使血管内皮功能失调。
