Abstract Objective: Left ventricular regional systolic function was evaluated in patients with early stage chronic kidney disease(CKD) using three-dimensional speckle tracking echocardiography(3D-STE). Methods: From June 2017 to September 2018, 40 patients with early CKD and 26 healthy volunteers(control group) were enrolled in our hospital. The patients were divided into CKD stage 2, CKD stage 3 and control group according to glomerular filtration rate, including 20 patients with CKD stage 2 and 20 patients with CKD stage 3. Conventional two-dimensional echocardiography and 3D-STE were performed, and the differences in parameters between the groups were compared. Results: ①In the CKD stage 2 group and control group, the strain values of apicallateral(AL), apicalseptum(AS), midinferior(MI), midanteroseptal(MAS), basalanterior(BA), basalanteroseptal(BAS), and basalposterior(BP) strain values were significantly reduced in systolic longitudinal strain(SLS), systolic area strain(SAS), systolic circumferential strain(SCS), systolic radial strain(SRS)(P<0.05); ②In the CKD stage 3 group and the CKD stage 2 group, the apex(Apex), AS, and midanterior(MA) strain values were significantly reduced in SLS, SAS, SCS, and SRS(P<0.05). There are more segmental differences in SLS. Conclusion: 3D-STE can be used to evaluate the left ventricular regional systolic function in patients with early CKD, and SLS is a sensitive index.
