目的 探讨实时三维超声心动图在评价慢性肾功能衰竭(CRF)患者左心室收缩同步性中的应用价值.方法 对30例CRF患者和 25 例正常对照组先行常规超声检查,获取M型左心室射血分数(M-EF)、左心室舒张末期内径(LVIDd)、左心室室间隔厚度(IVSD)、左心室后壁厚度(LVPWD);再采用三维超声心动图(RT-3DE)获取左心室全容积图像,并采用Qlab分析软件计算左心室17节段达到收缩期最小容积点时间(Tmsv)的标准差(Tmsv 16-SD、Tmsv 12-SD和 Tmsv 6-SD )及最大时间差 (Tmsv 16-Dif、Tmsv12-Dif和 Tmsv6-Dif),对标准差及最大时间差行心率校正,同时采集左心室舒张末期容积(LVEDV)、收缩末期容积(LVESV)、射血分数(LVEF)和心率(HR). 结果一般情况比较显示,CRF组HR、LVIDd、IVSd、LVPWd及LVESV均大于正常组(P＜0.05或P＜0.01),LVEF小于正常组(P＜0.05);时间-容积曲线同步性收缩参数比较显示,Tmsv6-SD及Tmsv6-Dif两组间差异无统计学意义(P＞0. 05),余参数CRF组均大于正常组 (P＜0.01或P＜0.05).结论 实时三维超声心动图能在同一心动周期内比较左心室各节段收缩的同步性,为临床评价CRF患者左心室内收缩不同步及心功能提供了简便、直观、无创性的新方法.

Objective To quantitatively evaluate the left ventricular systolic synchrony in patients with chronic renal failure (CRF) by real-time three-dimensional echocardiography (RT-3DE). Methods Thirty patients with CRF and twenty-five normal subjects were enrolled in this study.The M-mode ejection fraction (M-EF), left ventricular end diastolic internal diameter (LVIDd), interventricular septum diameter (IVSd), left ventricular posterior wall diameter (LVPWd) were obtained on two-dimension. The global and regional volume-time curves were obtained on three -dimensional. The end diastolic volume (LVEDV),end systolic volume (LVESV) and ejection fraction (LVEF) of left ventricule, the time to minimal systolic volume (Tmsv) of 16,12,6-segmental standard deviation (Tmsv16, 12, 6-SD), maximal difference (Tmsv16, 12, 6-Dif) were derived from Qlab software . The above parameters as a percentage of the cardiac cycle with different heart rates between patients were also calculated from the Qlab software, which were Tmsv16, 12, 6-SD% and Tmsv16, 12, 6-Dif %, rspectively. Results The indices of HR, LVIDd, IVSd, LVPWd and LVESV were significantly higher while LVEF was significantly lower in the CRF group than those of the control group (P<0.05 or P<0.01); The indices of systolic asynchrony of Tmsv16,12-SD%, Tmsv16,12-Dif, Tmsv16 ,12 ,6-SD/R-R%,Tmsv16,12,6-Dif/R-R% were significantly larger in the CRF group than those of the control group(P<0.05 or P<0.01). Conclusions RT-3DE provides a simple, intuitional and noninvasive approach to assess the systolic synchrony of all the LV segments simultaneously and LVEF in patients with chronic renal failure.
