摘要 目的:观察慢性肾脏病患者血浆同型半胱氨酸(Hcy)的变化,探讨血浆Hcy水平与左室重构的关系。方法:选择慢性肾脏病患者60例和健康对照者60例,采用化学发光法测定血浆总同型半胱氨酸(tHcy)水平,应用ATL公司HDI-5000型彩色多普勒超声诊断仪测定左室舒张末内径(LVDd)、室间隔厚度(IVST)、左心室后壁厚度(LVPWT)、左心室射血分数(LVEF)、舒张早期和晚期最大血流速度比(E/A),计算左心室重量指数(LVMI)。结果:慢性肾脏病患者高Hcy血症发生率为70%,而正常对照组高Hcy血症发生率为5%。慢性肾脏病患者Hcy水平[(27.29±25.87)μmol/L]明显高于正常对照组[(8.65±2.57)μmol/L](P<0.05)。慢性肾脏病高Hcy组与正常对照组间LVDd、IVST、LVPWT、LVMI、LVEF、E/A比值差异存在显著性(P<0.05)。LVDd、IVST、LVPWT、LVMI与血浆Hcy呈正相关(r分别为0.30、0.44、0.58、0.42,均P<0.05)。而LVEF、E/A比值与血浆Hcy呈负相关(r分别为-0.42,-0.45,均P<0.05)。这种相关性在应用多元回归剔除了性别、年龄、血压、血脂、血红蛋白等因素影响后仍然存在。结论:慢性肾脏病患者的高Hcy血症发病率高。高Hcy血症可能是慢性肾脏病患者心室重构的独立危险因素。
