Background: Aortic/central blood pressure (cBP) is an important determinant of cardiovascular risk. The SphygmoCor device applies a transfer function to radial BP waveforms calibrated to brachial systolic and diastolic BP (bSBP/bDBP) to estimate cBP parameters. Radial waveforms can be also calibrated to brachial mean BP (bMBP) and bDBP. Vicorder is a new cuff-based, operator-independent device which converts bBP waveforms to aortic waveforms to derive cBP.

Objective: to compare cBP estimated by non-invasive (Vicorder & SphygmoCor) devices to invasive cBP at cardiac catheterization.

Methods: Invasive BP (iBP) was measured in 33 patients (59±11 years, 63% males) undergoing diagnostic angiography, with a fluid-filled catheter at the aortic root. Simultaneous measurements were made using Vicorder and Sphygmocor. Brachial waveforms (Vicorder) were calibrated to oscillometric bSBP/bDBP; radial waveforms (Sphygmocor) were calibrated to oscillometric bSBP/bDBP and to bMBP/bDBP.

Results: Average (±SD) bSBP/bDBP was 145(±18)/81(±11) mmHg. iSBP/iDBP was 136/74(±18/9) mmHg; Vicorder-derived cSBP (137±17 mmHg) was in agreement with iSBP (mean ∆BP 0.3±8.0 mmHg, p=n.s.), while Vicorder-derived cDBP (81±11 mmHg) was higher than iDBP (mean ∆BP 7.0±7.4 mmHg, p<0.001). SphygmoCor bSBP/bDBP-calibrated cSBP (131±18 mmHg) under estimated iSBP (mean ∆BP −5.7±9.2 mmHg, p=0.002). SphygmoCor bMBP/bDBP-calibrated cSBP was higher than iSBP (141±17 mmHg, mean ∆BP 4.3±7.2, p=0.003).

Conclusions: Vicorder apparatus is highly accurate in non-invasive assessment of cBP compared with catheter-derived iSBP. SphygmoCor bSBP/bDBP-calibrated cSBP was lower than iSBP, while SphygmoCor bMBP/bDBP-calibrated cSBP was higher. Vicorder apparatus provides clinically useful values of cSBP.
