摘要

目的：探讨移植肾患者心功能指标与移植肾血流动力学参数之间的相关性。方法：依据左室Tei指数将103例肾移植患者分为3组：左室0.40＜Tei＜0.47为A组（51例）；左室0.47≤Tei＜0.79为B组（39例）；左室Tei≥0.79为C组（13例）。正常对照（Tei≤0.40）为D组（30例）。行常规超声心动图检查测量二尖瓣口血流频谱舒张早期和舒张晚期血流峰值之比（E/A），E峰减速时间（DT），左室射血分数（EF）以及Tei指数。腹部超声检查测量移植肾主肾动脉的收缩期峰值血流速度（PSV）、舒张期最小血流速度（EDV）、平均血流速度（MN）、阻力指数（RI）、搏动指数（PI）、肾血流量（Q）。结果：A组的各项血流动力学参数与对照组比较，差异无统计学意义，P＞0.05；B组和C组的各项血流动力学参数与对照组比较，差异有统计学意义，P＜0.05。EF与移植肾血流动力学参数PSV、EDV、MN、Q呈正相关，与RI、PI呈负相关；DT与PSV、EDV、MN、Q呈负相关，与RI、PI呈正相关；E/A值与移植肾各项血流动力学参数无明显相关性；Tei指数与PSV、EDV、MN、Q呈高度负相关，与RI、PI呈高度正相关。结论：肾移植后反映左心室整体功能的指标Tei指数与移植肾动脉各项血流动力学参数具有高度的相关性。

Abstract

Objective:　To investigate the correlative analysis of left ventricular functional parameters and the transplanted renal hemodynamic parameters. Methods: According to Tei index 103 patients with kidney transplantation were divided into group A(0.40＜Tei＜0.47, 51 cases), group B(0.47≤Tei＜0.79, 39 cases), group C(Tei≥0.79, 13 cases). The following indexes of cardiac function(E/A, DT, EF, Tei) were measured by echocardiography. The following hemodynamic parameters of transplanted kidney(PSV, EDV, MN, Q, RI, PI) were measured by abdominal ultrasound examination. Results:　There was no statistical significant difference in hemodynamic parameter between group A and D, P＞0.05. There was statistical significant difference in hemodynamic parameter between group B and C, P＜0.05. EF was positively correlated with PSV, EDV, MN, Q and negatively correlated with RI, PI. DT was negatively correlated with PSV, EDV, MN, Q and positively correlated with RI, PI. E/A had no significant correlation with hemodynamic parameters of transplanted kidney. Tei index was negatively significantly correlated with PSV, EDV, MN, Q and positively significantly correlated with RI, PI. Conclusions: For patients with kidney transplantation, Tei index reflected left ventricle allomeric function was significantly correlated with transplanted renal hemodynamic parameters.
