摘要
目的探讨脑梗死与血浆同型半胱氨酸(HCY)水平的关系。方法120例脑梗死患者测定血浆HCY、叶酸、维生素B12、颈动脉内膜中层厚度、欧洲脑卒中量表评分等指标,并与60例健康对照者相比较。结果①脑梗死组的血浆HCY水平、颈动脉内膜中层厚度和甘油三酯明显高于对照组,而叶酸及维生素B12水平则低于对照组(P均<0.01)。②脑梗死与HCY水平之间存在危险性的水平梯度,当HCY>15μmol/L时,患者发生脑梗死的危险为正常人的5.909倍,而HCY≥20μmol/L时,患者发生脑梗死的危险为正常人的10.545倍。③从各项监测指标的相对危险度来看,与脑梗死有关的因素分别为HCY、叶酸、维生素B12、甘油三酯、颈动脉内膜中层厚度和收缩压、舒张压。条件Logistic回归模型检验发现HCY、甘油三酯、高密度脂蛋白、颈动脉内膜中层厚度和收缩压为脑梗死的独立致病因素。④脑梗死组和对照组血浆HCY水平与血叶酸、维生素B12水平、欧洲脑卒中量表评分均呈显著负相关性;HCY水平与颈动脉内膜中层厚度呈显著正相关性。结论高同型半胱氨酸血症是脑梗死的独立致病因素,导致高同型半胱氨酸血症的原因可能是血浆内叶酸和维生素B12的降低。
