摘要
目的探讨脑梗死与血浆同型半胱氨酸(HCY)水平的关系。方法对120例脑梗死患者测定血浆HCY、叶酸、维生素B12等指标,并与60例健康对照者相比较。结果脑梗死组的血浆HCY水平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(均P<0.01);脑梗死与HCY水平之间存在危险性的水平梯度,当HCY>15μmol/L时,发生脑梗死的危险性为正常人的5.909倍,而HCY≥20μmol/L时,患者发生脑梗死的危险性为正常人的10.545倍;各项监测指标的相对危险性显示,与脑梗死有关的因素分别为HCY、叶酸、维生素B12、甘油三酯和收缩压、舒张压,条件Logistic回归模型检验发现HCY、甘油三酯、高密度脂蛋白和收缩压为脑梗死的独立致病因素;脑梗死组和对照组血浆HCY水平与血叶酸、维生素B12水平均呈显著负相关性。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。
