摘要
目的:探讨血浆同型半胱氨酸(Hcy)浓度与脑梗死TOAST亚型间的相关性。方法:362例脑梗死患者依据TOAST分型诊断标准确定亚型,酶法测定晨起空腹血浆Hcy浓度,秩和检验Hcy水平与TOAST亚型间相关性;彩色多普勒超声检查根据颈动脉内-中膜厚度、血管内膜形态、血流频谱将粥样硬化斑块分为易损和非易损斑块组,对比分析Hcy水平与斑块性质间关系。结果:①大动脉粥样硬化(LAA)型脑梗死患者血浆Hcy水平、高同型半胱氨酸血症(HHcy)发生率显著高于TOAST其他亚型;将心源性栓塞型、小动脉闭塞型、其他原因型、病因不明型4亚型合并为非LAA组后,LAA型Hcy水平和HHcy发生率仍然最高(P<0.05)。②Logistic回归分析显示HHcy是LAA型脑梗死的独立危险因素(OR=7.73,95% CI:2.99~20.01)。③LAA型脑梗死易损斑块组患者血浆Hcy浓度和HHcy发生率均显著高于非易损斑块组(P<0.05);多因素分析显示HHcy和糖尿病是易损斑块的独立危险因素。结论:血浆Hcy增高与TOAST分型中LAA亚型、颈动脉粥样硬化易损斑块密切相关,提示HHcy可能通过引发大动脉粥样硬化而导致脑梗死。
