目的 研究分析超声心动图在尿毒症血透患者透析前后心脏结构与功能改变中的应用价值。方法 选取2014年4 月-2016年1月在我院进行诊治的80例尿毒症血透患者，所有患者均于血透前后给予超声心动图检查，对比分析患者 治疗前后心脏结构与功能改变情况。结果 透析6个月后患者心结构指标LAD及LVEDD较治疗前无明显变化(P>0.05)， LVPM、ISVD、LVMI则较治疗前明显降低(P<0.05)，心功能指标CO、SV、E、A、E/A较治疗前无明显变化(P>0.05)， LVEF、FS、TEI则较治疗前明显改善(P<0.05)。结论 超声心动图应用于尿毒症血透患者透析前后，有助于对尿毒症 心功能损害程度做出早期判断，有效评价血透后心脏结构及功能变化情况。

Objective To study the application value of echocardiography through changes of cardiac structure and function in patients before and after dialysis in uremic patients. Methods 80 cases of uremia blood in April 2014-2016 year in January in our hospital for diagnosis and treatment of hemodialysis patients, all patients before and after hemodialysis with echocardiography, comparative analysis of patients before and after the change of cardiac structure and function. Results After 6 months of dialysis LAD and LVEDD index in patients with cardiac structure than before treatment had no significant change (P>0.05), LVPM, ISVD, LVMI were significantly lower than that before treatment (P<0.05), heart function index of CO, SV, E, A, E/A compared with before treatment, no significant changes (P>0.05), LVEF, FS, TEI were significantly improved compared with before treatment (P<0.05). Conclusion The use of echocardiography in hemodialysis patients before and after dialysis, helps to make early judgment on heart function in uremic hemodialysis can effectively evaluate the extent of the damage, after the heart Structure and function changes.
