Aims. Measurement of central blood pressure remains difficult. Also a good proxy for aortic pressure, carotid pressure is difficult to get through tonometry. Moreover, tonometry being a contact method, motion of the wall, especially if large, might alter the pressure waveform. We thus compared echotracking carotid distension waveforms with radial derived aortic waveforms for assessment of central pulse pressure.

Methods: We included 115 subjects aged 18–75 with valid carotid echotracking (ET) (Artlab, Esaote, Nl) and radial derived aortic waveforms (TO) (Sphygmocor, Atcor, Aus). Central SBP and PP were compared with correlations and Bland-Altman method. ET was calibrated using radial mean and diastolic blood pressure

Results: Correlation equation for SBP was ET-SBP=0.83*TO-SBP+32.9, R2=0.82. Correlation equation for PP was ET-PP=0.80*TO-PP+21.5, R2=0.71. Mean bias for SBP was −12±8 mmHg and −12±7 mmHg for PP.

Conclusion: Although waveforms appeared very similar and correlation were very narrow, there was a systematic overestimation of SBP and PP by echotracking, compared to tonometry. Whether this is overestimation by ET or underestimation by TO remains to be demonstrated
