Abstract: ［Abstract］ Objective〖HTSS〗〓To observe the effect of peritoneal dialysis and hemodialysis on the heart structure and function of the patients with endstage nephropathy, and to investigate the correlation between clinical indicators and the structure and function of the heart.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓One hundred and eighty patients with endstage renal disease were divided into 90 cases of peritoneal dialysis group and 90 cases of hemodialysis group according to different dialysis methods. The residual urine volume, blood pressure, blood lipids and blood biochemical parameters of the two groups were compared. All patients underwent cardiac color ultrasonography before and after dialysis, and interventricular septum thickness(IVST), left ventricular pesterior wall diastolic thickness(LVPWDT), left ventricular end diastolic diameter left ventricular enddiastolic diameter(LVEDD), left atrium diameter(LAAP), left ventricular ejection fraction(LVEF), and left ventricular myocardial mass index left ventricular myocardial mass index(LVMI) of two groups were observed. The relationships between above observations and LVMI were analyzed.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓After dialysis, the residual urine volume and total cholesterol in hemodialysis group were less than that in the peritoneal dialysis group. IVST, LVPWDT, LVEDD, LAAP, and LVMI in hemodialysis group were larger than the peritoneal dialysis group, differences were statistically significant(P＜005). The mean arterial pressure in the peritoneal dialysis group was significantly higher than that in the hemodialysis group, while the blood albumin content was decreased, with statistically significant differences(P＜005).The residual urine volume and mean arterial pressure were significantly different in the peritoneal dialysis group(P＜005). In patients with endstage renal disease, there was a positive correlation between LVMI and systolic pressure(r=0.379, P＜005), and a negative correlation between residual urine, hemoglobin and low density lipoprotein cholesterol(r=-0.423, -0.342, -0.289, P＜005).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓Hemodialysis has a greater impact on cardiac structure and function in patients with endstage renal disease than peritoneal dialysis, Peritoneal dialysis may be a more ideal method for patients with endstage renal disease.
