Abstract

Aims: To compare central systolic blood pressure (cSBP) and augmentation index (AIx) from 2 recently introduced devices Omron-HEM9000 (OM) and Arteriograph (AG) not using a transfer function with that of the widely used SphygmoCor (SC), which together with another radial device OM is calibrated on brachial BP.

Methods: Random-order manufacturer-recommended measurements using SC and OM (radial tonometry variants) and AG were taken on the left arm in 35 men (54±10yr) after >5mins supine rest. Results are means ±SD, or (95%CI of difference) for paired t-tests.

Results: cSBP by OM is slightly higher than by AG (4(1–7) mmHg, p=0.01). Both OM and AG estimate cSBP significantly higher than SC: 13(10–15) and 9(4–12) mmHg, respectively (p<0.001).

Late systolic shoulder of the radial pulse wave form measured by OM agreed with SC’s cSBP (SC-OM: 2(0–4) mmHg, p=0.06), but not with AG’s cSBP (AG-OM: 10(7–14) mmHg, p<0.001).

Radial AIx from SC and OM slightly disagree (SC-OM: 3(1–5)%, p=0.013) and both show close correlation (r=0.8) with AG’s brachial AIx. Aortic AIx by AG was lower than SC’s aortic AIx (8(6–10)%, p<0.001) but closely correlated (r=0.9).

Conclusion: Clinically significant higher cSBP values measured by two new methods AG and OM add to previous data suggesting that SC might be underestimating cSBP. Invasive studies involving all 3 devices across a wide age & BP range are needed.
