Does the CONNEQT Pulse device provide comparable measurements of central aortic blood pressure and vascular health biomarkers to the SphygmoCor XCEL device in adult patients?
The CONNEQT Pulse device demonstrates strong correlation and low bias compared to the SphygmoCor XCEL for central blood pressure estimation, supporting its potential suitability for home monitoring.
Introduction: The pulse wave analysis technology in the specialist SphygmoCor XCEL device has now been implemented in the CONNEQT Pulse device, which is a conventional sphygmomanometer suitable for home blood pressure (BP) monitoring. The aim of this study was to compare the correlation and consistency of measurements between the two devices. Methods: The study was conducted in participants admitted to the Department of Geriatrics, Ruijin Hospital, Shanghai Jiao Tong University School of Medicine. Brachial BP (bBP), central BP (cBP), augmentation pressure (AP), augmentation index (AIx), and subendocardial viability ratio (SEVR) were measured with the CONNEQT Pulse and the SphygmoCor XCEL devices, both using a calibrated cuff-based brachial waveform. Results: A total of 367 eligible subjects, aged 23–92 (57.6 ± 13.0) years, of whom 254 (69.2%) were male, was enrolled in this study. Paired t tests showed relatively low bias and elevated standard deviation: cSBP mm Hg (121.7 ± 17.2 vs. 117.5 ± 14.5, p
