However, previous measurements have been complex, operator dependent, or invasive. Recently, we developed a new automated oscillometric method to measure a brachial artery’s estimated area (eA) and volume elastic modulus (VE). The aim of this study was to investigate the reliability of new automated oscillometric measurement of eA and VE. Rest eA and VE were measured using the recently developed automated detector with an oscillometric method. eA was estimated using pressure-volume curves and VE was defined as follows [VE =Δ Pressure/ (100 × Δ Area/ Area) mmHg/%]. Sixteen volunteers (age 35.2 ± 13.1) underwent the oscillometric measurements and brachial ultrasound at rest and under nitroglycerin (NTG) administration. Oscillometric measurement was performed twice on different days. The rest eA correlated with brachial diameter measured by ultrasound (r = 0.75, P < 0.001). Rest eA and VE measurement showed good reproducibility (eA: ICC = 0.88, VE: ICC = 0 .78). Under NTG stress, eA was significantly increased (12.3±3.0 vs. 17.1±4.6 mm2, P < 0.001), which was similar to the case with ultrasound evaluation (4.46±0.72 vs. 4.73±0.75 mm, P < 0.001. VE was also decreased (0.81±0.16 vs. 0.65±0.11 mmHg/%, P < 0.001) after NTG. Cross-sectional vascular area calculated using this automated oscillometric measurement correlated with ultrasound measurement and showed good reproducibility. Therefore, this was a reliable approach and this modality may have practical application to automatically assess conduit artery diameter and elasticity in clinical or epidemiological settings.
