Introduction: The prognostic value of arterial stiffness has been shown in different groups of patients and also in apparently healthy populations. Several studies have already pointed out the prognostic importance of central Systolic Blood Pressure (cSBP)

Aim: To compare two devices that use indirect methods to asses central blood pressure: The SphygmoCor and OMROM HEM-9000AI.

Inclusion criteria

Age ≥18 years, Males and females, Arterial Hypertension

Methods: Eighty-four hypertensive subjects, mean age 58 ± 12 years were examined. Radial artery waveform recording at the left wrist was performed, patients with arrhythmias, severe hypertension, absence of radial pulse, diabetes were excluded.

Statistical software version 9.0 was used. Pearson’s correlations and Bland–Altman plots were used to assess the agreement between methods.

Results: cSBP measured with both devices values showed a significant correlation,r= 0.76; r²=0.58. cSBP values recorded with OMRON device were 16 mmHg higher (SD of difference = 13 mmHg) cSBP (Sphy) and pSBP2 (Omr) values showed a significant correlation (r= 0.74; r²=0.55, P <0.001) (Figure 1) mean difference was of −0.8, SD = 13 mmHg.

Conclusion: When compared both devices they offer discordant results, and this discrepancy tends to be larger at higher BP levels. In absence of invasive measurements of central aortic pressure, it is impossible to conclude which of the two systems provides cSBP values closer to true aortic cSBP. Our data suggest that pSBP2 reported by the Omron device more closely reflects the cSBP value assessed by the Sphygmocor device.
