Pulse wave analysis using the Mobil-O-Graph, Arteriograph and Complior device: a comparative study

AbstractPurpose: Pulse wave velocity (PWV) is a marker of arterial stiffness with major prognostic value. We compared Arteriograph and Complior devices with the Mobil-O-Graph for assessment of PWV and central systolic blood pressure (cSBP).Materials and Methods: We studied 316 consecutive subjects (age: 55 ± 14 years). For each individual, we measured PWV and cSBP with Arteriograph, Complior and Mobil-O-Graph and compared the readings. Differences in values among three devices were calculated for each measurement. We used Bland-Altman analysis, intraclass correlation coefficient (ICC) and coefficient of variation (CV).Results: Bland-Altman analysis indicated a mean difference for PWV: i.0.5 m/s (limits of agreement -1.4–2.4) between Complior and Mobil-O-Graph, ii.0.6 m/s (limits of agreement -1.4–2.6) between Arteriograph and Mobil-O-Graph. cSBP mean difference was 3.8 mmHg between Complior and Mobil-O-Graph (limits of agreement -12.5–20.1) and 9.2 mmHg between Arteriograph and Mobil-O-Graph (limits of ag...
