Title: Quantitative assessment of left ventricular systolic synchrony in patients with chronic renal failure using real-time three-dimensional echocardiography
Abstract: 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(P0.05 or P0.01);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(P0.05 or P0.01).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.
