Abstract
BACKGROUND AND OBJECTIVE: In dialysis patients, the cardiovascular mortality is 10 to 20 times higher than that in the general population. The increased arterial stiffness in patients with end-stage renal disease (ESRD) is an independent predictor of all-cause mortality. The arterial stiffness and atherosclerotic markers were evaluated in patients with ESRD treated with and without hemodialysis (HD) or peritoneal dialysis (PD).
SUCJECTS AND METHODS: 14 hemodialysis (mean dialysis duration 19.6 months), 14 peritoneal dialysis (mean dialysis duration 26.1 months) and 14 patients with ESRD prior to initiation of dialysis, and 27 age-sex matched controls were enrolled. The calculated central pulse pressure, plasma homocysteine, serum C-reactive protein, left ventricular mass index and aortic pulse wave velocity (PWV) were measured.
RESULTS: Patients with ESRD treated with and without dialysis had greater increases in their arterial stiffness and advanced atherosclerosis compared with the controls. However, there was no difference in the arterial stiffness and atherosclerotic markers before and after the dialysis treatment, or in the dialysis modality (HD, PD) of patients with ESRD. In a multiple regression model, PWV in patients with ESRD was explained by the level of plasma homocysteine (beta=0.396;p=0.027).
CONCLUSION: Atherosclerosis and arterial stiffness in patients with ESRD may not be affected by dialysis treatment or modality. In patients with ESRD, the level of plasma homocysteine is independently associated with arterial stiffness.
