Measurement of arterial stiffness by ultrafast echo: Comparison with echotracking in normotensive subjects and hypertensive patients

Because measurement of arterial stiffness is highly dependent on blood pressure (BP), methods independent of BP are required. Ultrafast echography (UFE, Supersonic Imagine, Aix en Provence, France) makes use of very fast sampling rate (up to 10 kHz), so transient events such as pressure wave arrival can be tracked. This method has never been tested against classical echotracking (Artlab, Esaote, Maastricht, NL) and carotid-femoral pulse wave velocity (cf-PWV, Sphygmocor, AtCor, Sydney, Australia).
