Introduction:
End stage renal disease (ESRD) is the terminal state of various chronic kidney diseases. Such patients often accompany with different degrees of myocardial remodeling and dysfunction. Hemodialysis is one of the main treatment methods for these patients. It removes excessive fluid and toxins in the body, with the decrease of preload, the final cardiac systolic and diastolic function will also change slightly.Therefore, echocardiography is needed to assess early changes in subclinical cardiac function in ESRD patients [1-3]. Evaluation of left atrial strain by speckle tracking imaging has been shown to play an important prognostic role in several different specific populations [4-7], but there are few studies on evaluation of left atrial strain before and after single hemodialysis.
