Abstract

Objective: To compare the short-term repeatability of aortic pulse wave velocity (PWV) measures obtained with non-invasive devices.

Methods: In 102 patients planned to undertake a cardiac catheterization (65±13 years, 70.6% males) duplicate non-invasive measures of PWV, 15-minutes apart, were obtained with 4 devices measuring two-points carotid-femoral PWV and the related pulse transit time (PTT): Complior (AlamMedical), PulsePenETT, PulsePenET (DiaTecne), SphygmoCor (AtCorMedical), and with 2 devices estimating PWV from the oscillometric cuff-derived brachial wave: BPLab (Petr Telegin), Mobil-O-Graph (IEM). PWV and carotid-femoral PTT measurements were compared using coefficients of variation (CV%) and their confidence intervals (CI).

Results: Devices evaluating carotid-femoral PWV showed a good repeatability (CV%[CI]: Complior: 8.8 [7.3–10.1]; PulsePen ETT: 8.0 [6.2–9.5]; PulsePen ET: 5.8 [4.9–6.6]; SphygmoCor: 9.5 [7.7–11.0]), whereas the repeatability of PWV estimated by cuff-based devices was for the BPLab = 5.5 [4.2–6.6] and for the Mobil-O- Graph = 3.4 [2.9–3.8]). A tendency toward a lower repeatability of carotid-femoral PWV was present for greater arterial stiffness, while repeatability of carotid-femoral PTT was not related to its mean values. Differences between repeated PWV measurements were not correlated with blood pressure (R2 = 0.005) or heart rate variations (R2 = 0.013).

Conclusions: Short-term repeatability of PWV measures was good, with some differences between different devices. A greater repeatability was observed in devices estimating PTT from a cuff-based measurement, compared to devices measuring carotid-femoral PTT, owing to the algorithm of calculation of PWV (Mobil-O-Graph) or to the procedure of correction which eliminates highly variable PWV values (BPLab).

Repeatability of PWV is not influenced by blood pressure or heart rate variations. For carotid-femoral PWV, the repeatability of measures is lower for higher PWV values.
