Effects of arteriovenous fistula on structure and function of left ventricle in patients with maintained hemodialysis / 中华肾脏病杂志

ABSTRACT

Objective To investigate the effects of arteriovenous fistula on structure and function of left ventricle in patients with maintained hemodialysis. Methods Levels of hemoglobin, inter-hemodialysis weight increase, blood pressure, diameter and blood flow of the fistula, structure and function of left ventricle were examined before and 12, 24 months after hemodialysis treatment in 44 patients who were divided into group A(low flow group, 900 ml/min) based on the fistula flow at the 24th month. Results Left ventricular end-diastolic diameter (LVDd), interventriculare septal thickness (IVST) and left ventricular mass index (LVMI) increased gradually as the time of hemodialysis going on. The cardio-cheat proportion also increased as well as ejection fraction (EF) and the peak velocity ratio of early and late diastolic period(E/A), especially significantly increased in group B. Cardio-chest proportion , LVDd and LVMI were higher and E/A lower in patients with severe sodium retention than those with mild sodium retention in both groups. The fistula flow was positively related to LVDd and LVMI( P
