摘要 目的探讨血浆一氧化氮(NO)、同型半胱氨酸(Hcy)水平与高同型半胱氨酸中毒(HHcy)患者颈动脉斑块稳定性的关系。方法选取含有颈动脉斑块HHcy患者163例,根据颈动脉超声结果分为稳定斑块组和不稳定斑块组。观察2组患者血浆NO和Hcy水平。结果不稳定斑块组Hcy水平(24.92±2.01)mol/L显著高于稳定斑块组(18.14±2.98)mol/L(P=0.021);而不稳定斑块组血浆NO水平(45.19±8.59)μmol/L显著低于稳定斑块组(58.24±6.54)μmol/L(P=0.002)。相关分析显示,HHcy患者Hcy水平与颈动脉斑块不稳定性呈正相关(回归系数为0.071;P=0.006),血浆NO水平与颈动脉斑块不稳定性呈负相关(回归系数为-0.014;P=0.001)。结论 HHcy患者中,血浆Hcy升高可增加发生不稳定性颈动脉斑块风险,可能与Hcy所导致的NO水平减少有密切关系。
