Objective: Previous studies have shown that the pressure at the late systolic shoulder (SBP2) of the radial or digital pressure waveform is a good estimate of central systolic pressure (cSBP) when waveforms are calibrated from invasive measurements. These results suggest SBP2 may remain constant along the upper limb. The aim of this study was to examine the agreement between SBP2 at the carotid, brachial and radial arteries.
Methods: We compared measurements of SBP2 obtained by applanation tonometry using the SphygmoCor system (Atcor Medical, Australia) at the radial (RA), brachial (BA) and carotid (CA) arteries on 45 subjects (24 men, aged 23–84 years). Waveforms were calibrated using the same mean (MAP) and diastolic blood pressure (DBP).
Results: There was a close agreement between SBP2 values measured at the different sites with a mean difference (SD) of 0.88 (5.29) mmHg for RA-BA, −2.30 (4.60) mmHg for BA-CA and −1.42 (4.34) mmHg for RA-CA.
Conclusion: These results suggest that SBP2 can be considered as constant along the arm.
