Abstract
Objective: To compare the pulse wave velocity (PWV) results obtained by Sphygmocor AtCor Medical, by radial tonometry, and Mobil-Ambulatory Blood Pressure Monitor-Pulse Wave Velocity (Mobil-ABPM-PWV) 24 hours, an oscillometric method. Design and method: Sixty-three controlled hypertensive (41 female and 22 male) and sixty-three resistant hypertensive (36 female and 27 male) patients were recruited and submitted to evaluation of arterial stiffness by the SphygmoCor (radial tonometry) and by Mobil-ABPM-PWV (oscillometric method). Linear regression and Bland-Altmann test were used to statistics analysis. Results: The correlations of the PWV as assessed with Mobil-ABPM-PWV 24 hours with the values obtained using the SphygmoCor radial tonometry were significant (controlled hypertensive patients: r = 0.54, P < 0001; resistant hypertensive patients: r = 0.48, P < 0.001). Comparison Bland-Altman plot showed concordance correlation coefficient (controlled hypertensive patients = 5.0, P < 0.0001 and resistant hypertensive patients = 4.8, P < 0.0001). Figures 1–4. Conclusions: The oscillometric method Mobil-ABPM-PWV is an easy-to-use and time-effective method for assessing arterial stiffness compared with the SphygmoCor AtCor radial tonometry.
