Abstract

Objectives: Mortality rate in end-stage renal disease (ESRD) are still at a high level. Sarafidis et al. showed the predictive value of 48h PWV in patients undergoing hemodialysis [1], although recent studies using office measurement showed controversial predictive results. Aim of the present study was to confirm the predictive value of a novel oscillometric measurement of pulse wave velocity on mortality in an elderly cohort of patients with ESRD.

Methods: The ISAR study is a prospective and longitudinal study targeting patients with ESRD undergoing hemodialysis. Oscillometric measurement of 24-hour PWV was performed at baseline. Survival analysis included Kaplan-Meier analysis, logrank test and Cox regression.

Results: A total of 350 patients had a median age of 69.3 [55.8; 77.3] years. Mean PWV was 9.6 (2.2) m/s and 120 patients died during the mean follow-up of 45 months. PWV was significantly higher in the deceased (10.6 +/− 1.9 m/s) than in surviving patients (9.0 +/− 2.2 m/s). Kaplan-Meier analysis showed differences in dichotomized PWV (cut-off 10 m/s [2]; Logrank test: p = 0.001). For results of univariate Cox regression, see Figure. Adjusted Cox regression analysis showed a significant risk prediction for all-cause mortality (HR 2.322; p = 0.011). Patients older than 50 years showed even higher predictive values (HR 2.442; p = 0.008) as well as patients with PWV values of at least 10 m/s (HR 3.300; p = 0.006).

Univariate hazard-ratios and their 95% confidence intervals for continuous PWV and PWV quartiles (Q1 as reference; ** p = 0.002; *** p < 0.001). Ql: <=7.92 m/s; Q2: 7.92–9.83 m/s; Q3: 9.83–11.23 m/s; Q4: >11.23 m/s.

Conclusion: Oscillometric measurement of 24-hour pulse wave velocity is a simple and valid method and has an additional predictive value for all-cause mortality in elderly patients with end-stage renal disease.
