摘要 目的分析糖尿病肾病患者心脏结构及功能的改变及其与相关因素的关系。方法对48例血清肌酐〈445μmol/L、未行血液净化的糖尿病肾病患者的血压、血红蛋白、血生化指标、尿微量白蛋白排泄率、血浆甲状旁腺素和胰岛素等进行检测,描记超声心动图,计算左心室心肌重量指数(LVMI),对心脏的结构和功能特征进行分析,并对LVMI与上述指标进行相关分析。结果48例中有左心室肥厚(LVH)者占58.3%,其中向心性肥厚占37.5%;无LVH而有向心性重构者占16.7%;20.8%左心室收缩功能障碍;有LVH组和无LVH组的血红蛋白、收缩压、血清白蛋白、血脂、血浆甲状旁腺激素以及内生肌酐清除率等,均存在明显差异;LVMI与血红蛋白、内生肌酐清除率呈负相关(r值分别为-0.34、-0.45,P值分别为P〈0.05、P〈0.01),与血浆全段PTH(iPTH)、尿微量白蛋白排泄率以及甘油三酯呈正相关(r值分别为0.514,0.35、0.48,P值分别为0.01、〈0.05、〈0.01)。结论处于透析前期糖尿病肾病患者,左心室肥厚尤其向心性肥厚发生率比较高,收缩压、贫血、高脂血症、营养不良、肾损害程度、代谢性酸中毒、继发性.甲旁亢等都是重要的影响因素,早期检查心脏结构和功能,及早对这些影响因素进行干预具有重要意义。
