Evaluation of eSie VVI Technology on Left Ventricular Systolic Function Changes in Uremic Patients Undergoing Dialysis.

To analyze the longitudinal peak systolic strain of left ventricular myocardium in three layers before and after hemodialysis in uremic patients, and to explore the value of eSie VVI (Velocity Vector Imaging) technology in evaluating the changes of left ventricular myocardial systolic function in uremic patients in a short time after hemodialysis, the longitudinal peak systolic laminar strain and global full-thickness strain of 17 segments of the left ventricle are obtained by eSie VVI software analysis, and the results are deduced in Excel form. Statistical analysis is made on the results of longitudinal peak systolic stratified strain of left ventricular inner, middle and outer layers and whole myocardium in uremic patients before and after hemodialysis. The results show that eSie VVI technology can more sensitively and accurately evaluate the changes of left ventricular myocardial systolic function after hemodialysis in uremic patients, and has certain clinical value.
