Validity Of Withings Pulse Wave Velocity Scale Versus Gold Standard Applanation Tonometry And Body Composition Analysis In A Young Healthy Population

Cardiovascular disease currently is the leading cause of death nationwide. Pulse Wave Velocity (PWV) is now considered a gold standard for measuring arterial health. Deleterious changes in arterial distensibility are risk factors for cardiovascular disease. The Withings Body Cardio Scale has been marketed to the general population for its ability to measure PWV in the home, however, there are no data that demonstrate the accuracy of this technology. The PURPOSE of this study was to determine the accuracy and reproducibility of PWV with the Withings Body Cardio. METHODS 20 normotensive healthy young adults enrolled in this study. Two measurements with each operating system were obtained over a period of 30 minutes. Standing PWV measurements with SphygmoCor were utilized in order to maintain ecological validity with the scale. RESULTS Significant differences were observed in measurement of fat mass and fat-free mass. No significant differences were found between Withings and SphygmoCor equipment. CONCLUSION There were no clinical differences detected between devices in the measurement of PWV, suggesting the home-based system of tracking PWV using the Withings scale can be an accurate measurement of systemic PWV. Monitoring cardiopulmonary health at home can be useful in providing clinical insight for longitudinal healthcare monitoring.
