Assessment of left atrial volume and function by real-time three-dimensional speckle tracking imaging in end-stage renal disease patients with different dialysis methods / 中华超声影像学杂志

ABSTRACT

Objective:To discuss the value of real-time three-dimensional speckle tracking imaging(RT3D-STI) in the evaluation of the left atrial (LA) volume and function in end-stage renal disease (ESRD) patients with different dialysis methods.Methods:Eighty-three ESRD patients who were treated in the Affiliated Hospital of Qingdao University from February to August 2019 were enrolled and divided into non-dialysis group ( n=25), hemodialysis group (HD group, n=31) and peritoneal dialysis group (PD group, n=27). And 30 healthy volunteers were enrolled as control group. Subsequently, the LA volume indexs including LA maximal volume index (LAVImax), LA minimal volume index (LAVImin) and LA presystolic volume index (LAVIpre), the LA function parameters including LA ejection fraction (LAEF), LA passive ejection fraction(LApEF) and LA active ejection fraction (LAaEF) and the LA global strain parameters including global longitudinal strain(GLS), global radial strain(GRS) and global circumferential strain(GCS) were obtained by RT3D-STI. The differences of the parameters among these groups were compared and the correlations between the myocardial strain parameters and dialysis time were analyzed. Results:①The LAVImax, LAVImin and LAVIpre of the non-dialysis group, PD group and HD group were higher than those in the control group, while the LAEF, LApEF, GLS, GRS and GCS were lower than those in the control group(all P<0.05); the LAVImin of the PD group as well as the LAVImin, LAVIpre and LAVImax of HD group were higher than those of non-dialysis group, while the LAEF, LApEF, GLS, GCS of the PD group and the LAEF, LApEF, GLS, GRS, GCS of HD group were lower than those of non-dialysis group (all P<0.05). The LAVImax, LAVImin, LAVIpre of HD group were higher than those of PD group, while the LAEF, LApEF, GLS, GRS and GCS of HD group were lower than those of PD group (all P<0.05). ②The GLS and GCS in PD group were negatively correlated with the dialysis time( r=-0.670, -0.596, all P<0.05), and the GLS, GCS and GRS in HD group were negatively correlated with the dialysis time( r=-0.624, -0.631, -0.551, all P<0.05). Conclusions:RT3D-STI can assess the LA volume and function of ESRD patients with different dialysis methods effectively and can further evaluate the prognosis of patients and guide timely clinical intervention.
