Reproducibility of pulse-wave analysis and pulse-wave velocity determination in chronic kidney disease

摘要

Background. Indices of central arterial stiffness, derived by use of applanation tonometry, have shown to be strong independent predictors of cardiovascular morbidity and mortality in patients with chronic kidney disease (CKD). The objective of this study was to evaluate the intra- and inter-observer and day-to-day reproducibility of pulse-wave analysis (PWA) and pulse-wave velocity (PWV) in pre-dialysis patients with CKD stages 3–5 using applanation tonometry with the SphygmoCor® software and hardware.
