RESUMO
Objective To assess the mortality and risk factors for stroke among dialysis patients with different dialysis modality. Methods 590 patients who underwent hemodialysis (HD) or peritoneal dialysis (PD) from January 2008 to December 2012 were recruited in our study, and categorized according to dialysis modality. The prognostic risks of stroke were hazard ratio of risk was calculated by Cox regression analysis in HD and PD patients respectively. by the Kaplan?Meier curves or the Cox proportional hazards model. Results A total of 590 patients is under a median follow?up of 32.5 months. The stroke incidence rate of 49.2/1, 000 patient?years in total patients, and 74.1/1, 000 patient?years in HD patients, which was significantly higher compared with that of 31.8/1,000 patient?years in PD patients. On multivariate analysis, independent predictors of stroke occurrence were age(HR=1.05;95%CI:1.02~1.09;P=0.003)、diabete(HR=1.98;95%CI:1.31~3.46;P=0.001)、CVD(HR=2.06;95%CI:1.62-3.05;P < 0.001)、Total triglycerides(HR = 1.20; 95% CI:1.08-1.58; P = 0.034) and hemodialysis (HR = 2.03; 95% CI:1.46-3.89; P = 0.005). Conclusions Age, diabete, CVD, total triglycerides and hemodialysis are independently associated with increased stroke risks in dialysis patients, which suggest that these patients should pay attention to weight control and glucose control.
