Background: Recently, new devices using oscillometric cuff have been developed to derive central blood pressure (BP) waveform from brachial BP waveform. Late systolic pressure augmentation of central BP waveform is a marker of central hemodynamics. Mobil-O-Graph, a cuff-based oscillometric device, can assess central augmentation pressure (AP) together with central BP. Central AP measurement using the Mobil-O-Graph in the European population was reported to be associated with age and sex. However, factors influencing central AP in the Asian population have not been shown. Objectives and Methods: We enrolled 110 normotensive volunteers (50 men; age range, 21‒76 years). Central BP and AP were measured using the Mobil-O-Graph on the left arm with the subjects in the seated position after resting for at least 5 min. We compared central hemodynamics between the sexes. We investigated factors influencing central AP in uni- and multivariate linear regression analyses and age-related change in central AP using the Mobil-O-Graph in healthy Japanese individuals. Results: Central AP were lower in men than in women (5.5 ± 2.8 vs. 11.0 ± 4.7 mm Hg, p < 0.001). The central AP in the total cohort was positively correlated with age (r = 0.325, p < 0.001) and inversely correlated with height (r = −0.601, p < 0.001) in the Pearson correlations. In multivariate regression analysis, the parameters influencing central AP (R2 = 0.467) were age (β = 0.097, p < 0.001), sex (β = −2.890, p = 0.010), and height (β = −0.153, p = 0.031). The central AP (10.0 ± 4.8 mm Hg) in the ≥50-year-old group significantly increased compared with those in the 20- to 39-year-old group (6.7 ± 4.2 mm Hg, p < 0.05). Conclusions: Age, sex, and height influenced central AP, as assessed using the Mobil-O-Graph. Age-related increase in central AP was observed in normotensive Japanese individuals. Brachial cuff-based waveform recordings using the Mobil-O-Graph are feasible for the estimation of central AP in the Asian population.
