目的探讨肾移植后近期对患者心脏形态和机能的影响,评估肾移植的效果。方法于肾移植前两次血透之间及肾移植后半年内和半年后,采用彩色多普勒超声心动图、胸片、心电图及有关实验室检查,分别测定与心脏形态和机能相关指标,以辛普森法测定心功能。结果肾移植后6个月内与肾移植前对比AV血流速度显著改善(P<0.05),肾移植后6个月以上与肾移植前对比LV,LA,IVSD和LVPWD及每搏量(SV)、二尖瓣血流E峰、A峰都有显著改善(P<0.05),心电图明显好转,实验室有关指标达到正常。结论肾移植后,近期内对患者术前存在的心功能异常有显著改善,随着时间的推移心功能各项指标改善尤为明显。
Objective To investigate the effect of renal transplantation on the morphology and function of the heart after renal transplantation and evaluate the effect of renal transplantation. Methods Color Doppler echocardiography, chest radiograph, electrocardiogram and related laboratory tests were performed between the two hemodialysis patients before renal transplantation and within six months and six months after renal transplantation. The indexes related to cardiac morphology and function were measured respectively. Simpson method to determine cardiac function. Results AV blood flow velocity was significantly improved within 6 months after renal transplantation compared with that before kidney transplantation (P <0.05). After 6 months of renal transplantation, the blood pressure of AV, LV, LA, IVSD, LVPWD and stroke volume ), Peak E and peak A of mitral flow were significantly improved (P <0.05), electrocardiogram significantly improved, laboratory-related indicators to normal. Conclusions After renal transplantation, the abnormal cardiac function in patients with preoperative renal failure has been significantly improved, with the improvement of cardiac function indicators over time is particularly evident.
