Comparison of Non-Invasive Estimation of Central Aortic Blood Pressure and Biomarkers of Vascular Health Measured by Two Devices Using Brachial Cuff Waveforms

Both devices show strong cBP-bBP correlations and low bias, suggesting that the new CONNEQT Pulse provides similar measurements of cBP to the original SphygmoCor XCEL. Although there is greater variability in waveform parameters, the magnitude of differences is within acceptable limits for meaningful use in conventional home BP monitoring. The relatively elevated variability in measurement precision (standard deviation), most likely due to sequential measurements with both devices in the same arm, needs to be further evaluated using simultaneous measurements in both arms.
