Evaluation of Pulse Wave Velocity and Augmentation Index in supine and sitting position
Nürnberger J, Michalski R et al; Artery Research Vol 3 (2009).
Despite the introduction of arterial stiffness measurements in the recommendation of the European Societies of Hypertension and Cardiology, pulse wave velocity (PWV) and augmentation index (AI) are still not used routinely in clinical practice. Possibly, current techniques, although non-invasive, validated, and easy to use, are still impractical and not favoured by patients. This includes the ability to perform such measurements in the sitting position as is done for blood pressure. New devices allow measurements in the sitting position. The aim of this study was to evaluate the role of posture on PWV and AI, and to assess whether arterial stiffness measurements can be reliably measured in the supine position.
