Accuracy of a Newly-Introduced Oscillometric Device for the Estimation of Arterial Stiffness Indices in Patients on Peritoneal Dialysis: A Preliminary Validation Study.

Accuracy of a Newly-Introduced Oscillometric Device for the Estimation of Arterial Stiffness Indices in Patients on Peritoneal Dialysis: A Preliminary Validation Study. Adv Perit Dial. 2018 Nov;34(2018):24-31 Authors: Vaios V, Georgianos PI, Pikilidou MI, Eleftheriadis T, Zarogiannis S, Papagianni A, Zebekakis PE, Liakopoulos V Abstract The aim of the present study was to compare the aortic systolic blood pressure (aSBP), heart-rate-adjusted augmentation index (AIx75), and pulse wave velocity (PWV) obtained using the Mobil-O-Graph (IEM, Stolberg, Germany) and SphygmoCor (AtCor, Sydney, Australia) devices in patients receiving peritoneal dialysis (PD).After a 10-minute rest in the supine position, the Mobil-O-Graph and SphygmoCor devices were applied in randomized order in 27 consecutive PD patients. The agreement between the measurements produced by the Mobil-O-Graph and SphygmoCor devices was explored using Bland-Altman analysis.The Mobil-O-Graph-derived aSBP, AIx75, and PWV did not differ from the same measurements obtained with SphygmoCor (aSBP: 120.5 ± 18.2 mmHg vs. 124.4 ± 19.0 mmHg, p = 0.438; AIx75: 27.0% ± 12.4% vs. 24.5% ± 10.6%, p = 0.428; PWV: 9.5 ± 2.1 m/s vs. 10.1 ± 3.1 m/s, p = 0.397). The slight difference in the estimation of aSBP is possibly explained by the difference in brachial SBP used for the calibration of the devices (131.0 ± 20.6 mmHg vs. 134.5 ± 19.7 mmHg, p = 0.525). Mobil-O-Graph-derived measuremen...
