How to interpret 24-h arterial stiffness markers: comparison of 24-h ambulatory Mobil-O-Graph with SphygmoCor office values

The objective of this study was to compare 24-h mean values of arterial stiffness parameters obtained using 24-h ambulatory blood pressure monitoring device (Mobil-O-Graph) against a validated single-measure tonometric system (SphygmoCor). Materials and methods We measured brachial and central arterial pressure, augmentation index (AIx), and carotid-to-femoral pulse wave velocity (cfPWV) using SphygmoCor device in 82 high and very high cardiovascular risk patients. The Mobil-O-Graph device for the 24-h blood pressure and arterial stiffness parameter monitoring was used on the same day and started within 2 h after measurements using SphygmoCor were done. Results Mean AIx values were 26.38±9.95 for SphygmoCor office measurement and 26.69±8.45 for Mobil-O-Graph 24-h mean values. The mean difference was −0.31±9.78 (P=0.775). CfPWV values were 10.56±2.59 m/s for SphygmoCor office measurement and 8.72±1.29 m/s for Mobil-O-Graph 24-h mean values. The difference of 1.84±2.15 m/s was statistically significant (P
