True Arterial Stiffness Does Not Change between Dialysis Sessions during 1 Week in Outpatients on Intermitted Hemodialysis.

Introduction: End-stage renal disease (ESRD) is associated with exponentially elevated cardiovascular mortality. Arterial stiffness (AS) - usually expressed with pulse wave velocity (PWV) - is an established independent predictor of cardiovascular risk beyond the traditional risk factors. Higher PWV values are frequently observed in patients with ESRD.
