动态监测尿毒症血液透析患者超声心动图的意义

The clinical significance of ultrasound cardiogram tests in uremia patients with hemodialysis

目的观察尿毒症血液透析患者超声心动图 (UCG)的动态变化 ,并探讨相关危险因素。方法采用UCG对83例尿毒症患者左房内径(LAD)、左室内径(LVD)、室间隔厚度(IVST)、左室后壁厚度(IVPWT)、E/A值进行动态检测 ,并探讨UCG多次异常与透析间期体重增加过多、高血压、营养不良、透析不充分等因素的相关关系。结果尿毒症患者左室内径、左房内径、室间隔厚度、左室后壁厚度明显增高 ,E/A值降低 ,与正常对照组比较存在显著性差异 (P<0.05) ;UCG多次异常与患者透析间期体重增加过多、高血压、营养不良、透析不充分等密切相关。结论尿毒症患者存在UCG的异常 。

Objective To investigate the clinical significance of ultrasound cardiogram(UCG)tests in uremia patients and analyze its risk factors. Methods Left atrium diameter (LAD), left ventricular diameter (LVD), interventricular septum thickness (IVST), left ventricular posterior wall thickness (IVPWT) and E/A of 83 uremia patients were measured by UCG,and correlated to clinical features, such as body weight,blood pressure,levels of albumin. Results The LAD,LVD, IVST, IVPWT of uremia patients were significantly higher than that of normal controls, and the E/A was significantly lower than that of normal controls (P<0.05); the frequent abnormal of UCG were correlated to body weight,hypertension,malnutrition and dialysis inadequacy. Conclusion Uremia patients have abnormal change of ultrasound cardiogram; the follow_up ultrasound cardiogram can be used to assess and manage the uremia patients with hemodialysis
