The Application of 2-Dimensional Speckle Tracking Imaging in Evaluating Left Atrial Function Before and after Hemodialysis in Uremia
Objective The aim is to detect the structural and functional changes of the left atrium in uremia before and after hemodialysis by using two-dimensional speckle tracking echocardiography.Methods 100 cases of uremia at depart-ment of nephrology,Benq hospital affiliated to Nanjing medical university from July 2022 to June 2024 were enrolled as the ob-servation group.The pre-scheduled examination items were executed before and after 2 hours of hemodialysis treatment.100 normal cases whose age and gender distribution matches the observation group were set as the control group.The control group was tested once during the physical examination,and the parameters were same as observation group.The routine echocardio-graphy and 2D-STE were performed to measure LASr,LAScd and LASct,then statistical analysis.Results Compared with the control group,the observation group had lower LASr and LASct,and higher LAScd.The differences were statistically sig-nificant.(P＜0.05).Conclusion 2D-STE was capable for measuring left atrial dysfunction in uremia and evaluate the im-provement of atrial function in hemodialysis patients.Hemodialysis is beneficial for the recovery of left atrial function.
