Abstract:
Objective To evaluate global left ventricular(LV) strain of patients with chronic renal failure(CRF) by three-dimensional speckle tracking imaging(3D-STI) and discuss the possible association between global peak strain and ejection fraction of LV.Methods The study includes 22 patients in the renal failure period,25 patients with uremia (pre-dialysis),and 20 healthy controls.Global peak longitudinal strain (GPSL),global peak area strain(GPSA) and global peak radial strain(GPSR) were measured by 3D-STI.Then possible association between GPSL,GPSA,GPSR and LVEF were discussed by the Pearson correlation analysis.Results The GPSL,GPSA,GPSR were statistically different in the control group,patients in the renal failure period and patients with uremia.There were significant differences between groups(F =13.28,4.65,4.68,P ＜ 0.01) as following,all of GPSL,GPSA,GPSR were lower in uremia group compared with control group [q =7.48(GPSL),4.19(GPSA),4.72(GPSR),P ＜0.01],GPSL was lower in renal failure group compared with control group [q =4.9 (GPSL),P ＜0.01].The Pearson correlation analysis revealed GPSL,GPSA,GPSR were strongly associated with LVEF(r =-0.679,-0.781,0.719,P ＜0.01).Conclusions In patients with CRF,the global peak strain can reveal the systolic function of left ventricle and the global peak longitudinal strain can recognize systolic dysfunction more sensitively.
