目的:探讨颈动脉内中膜厚度与H型高血压及相关因素的关系。方法:选取244例高血压患者,根据同型半胱氨酸(Hcy)水平分为H型高血压组(Hcy≥10μmol/L)、非H型高血压组(Hcy<10 μmol/L),测量颈动脉内中膜厚度(IMT),观察有无斑块、斑块位置及类型,计算斑块积分并测量血甘油三酯(TG)、胆固醇(TC)、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)等指标;同时收集年龄、性别、病程等流行病学资料。结果:H型高血压组颈动脉IMT、斑块积分、斑块检出率、合并脑梗死及冠心病构成比均高于非H型高血压组,两组间差异有统计学意义(P<0.05)。相关分析显示:颈动脉IMT与Hcy、FBG、HDL-C、年龄及高血压病程有相关性。结论:H型高血压与颈动脉内中膜厚度密切相关,HHcy可在高血压的基础上加速动脉硬化的进程。
