BACKGROUND: Cardiovascular diseases are the leading cause of death in patients who receive chronic renal replacement therapy. These patients undergoing maintenance hemodialysis through arteriovenous fistula develop both structural and functional cardiovascular abnormalities. The aim of this study was to assess the effect of arteriovenous fistula on left ventricular structural and functional parameters.
METHODS: Seventy individuals with end-stage renal disease were involved in this study, recruited from the Department of Vascular Surgery, Qena University Hospital, South Valley University, Qena, Egypt. AVF was created for every subject, preoperative echocardiography was performed in addition to two follow-up echocardiography studies after one and half month and 3 months postoperatively.
RESULTS: The overall patients mean ages were 54.1±13.4 years, 40% were males and 60% were females. After 1.5 months there was no statistically significant change in the functional parameters of the left ventricle (LV), while there were significant changes in the left ventricular posterior wall diameter (LVPWD), interventricular septum at end diastole (IVSd), and left ventricular mass (LVM). After 3 months of creating AVF, transthoracic echocardiography showed significant changes in both functional and structural parameters of the LV.
CONCLUSIONS: AVFs have a substantial effect on structural and functional remodeling of the LV.
