将25例维持性血透患者分成A、B两组,其中A组甲状旁腺激素(PTH)<正常值上限3倍,B组PTH>正常值上限3倍。通过对A、B两组患者的心超检测,了解尿毒症患者心脏结构与功能改变与血PTH的关系。结果显示,B组室间隔厚度、左心室后壁厚度、左心室心肌重量指数均高于A组。B组舒张功能异常发生率为69%,明显高于A组的25%。两组患者的收缩功能差异不显著。提示尿毒症患者血PTH增高是影响左心室结构与功能的重要因素。
25 cases of maintenance hemodialysis patients were divided into A, B two groups, including group A parathyroid hormone (PTH) <3 times the upper limit of normal, B group PTH> 3 times the upper limit of normal. Through the A, B two groups of patients with cardiac ultrasonography to understand the uremic patients cardiac structure and function changes and blood PTH. The results showed that the thickness of interventricular septum, left ventricular posterior wall thickness, left ventricular myocardial mass index were higher in group B than in group A. The incidence of diastolic dysfunction in group B was 69%, which was significantly higher than that in group A (25%). There was no significant difference in systolic function between the two groups. Prompted uremic patients with elevated blood PTH is an important factor affecting left ventricular structure and function.
