This study compared office and ambulatory measurements of PWV and observed the changes in PWV after lifestyle modifications or initiation of antihypertensive medication. The results showed significant differences between office and ambulatory measurements, suggesting that the two methods are not interchangeable.
Objective: Pulse wave velocity (PWV), the most accepted biomarker of arterial stiffening can be measured by different methods and in the past decade, its 24 h monitoring has also become available. The aim of our study was to compare office and ambulatory PWVs and in a proportion of patients to compare the changes of PWVs after the initiation of lifestyle modifications or antihypertensive medication. Methods: Office carotid-femoral PWV was measured with the tonometric PulsePen device (PP PWV), first hour and 24 h ambulatory oscillometric PWVs were evaluated with Mobil-O-Graph (MOB first hour PWV and MOB 24 h PWV, respectively). In new hypertensive patients, the measurements were repeated 3 months after the initiation of antihypertensive medication. In white-coat hypertensive patients after lifestyle modifications the measurements were repeated at 12 months. Results: One hundred and five participants were involved with 22 new hypertensive and 22 white-coat hypertensive (WhHT) patients. PP PWV [8.7 (7.3-9.9) m/s] differed from MOB first hour PWV [7.3 (6.5-8.8) m/s] and MOB 24 h PWV [7.4 (6.4-8.8) m/s] as well (P < 0.05). PP PWV significantly decreased both in hypertensive [by 0.9 (0.4-1.5) m/s, P < 0.05] and WhHT patients [by 0.3 (-0.1 to 1) m/s, P < 0.05]. MOB first hour PWV did not change neither in hypertensive patients, nor in WhHT patients. MOB 24 h PWV decreased only in hypertensive patients [by 0.2 (0-0.6) m/s], which was less pronounced compared with PP PWV (P < 0.05). Conclusion: The significant differences observed both in the cross-sectional and in the prospective parts of our study suggests that the two methods are not interchangeable.
