Berukstis A, et al. - Using 24-hour ambulatory blood pressure monitoring device (Mobil-O-Graph) against a validated single-measure tonometric system (SphygmoCor), 24-hour mean values of arterial stiffness parameters were compared. Researchers examined 82 high and very high cardiovascular risk patients by using SphygmoCor device to determine brachial and central arterial pressure, augmentation index (AIx), and carotid-to-femoral pulse wave velocity (cfPWV). Following assessments with SphygmoCor, they used Mobil-O-Graph device within 2 hours for 24-hour blood pressure and arterial stiffness parameter monitoring. They found moderate agreement between SphygmoCor single measurement and Mobil-O-Graph 24-hour mean values of arterial stiffness parameters. Mobil-O-Graph provided significantly lower 24-hour mean values of cfPWV vs SphygmoCor values obtained in the office, whereas 24-hour AIx mean values did not have a significant bias.
