Abstract des Autors
Pulse wave velocity (PWV) measurement is widely used for the indirect assessment of arterial wall distensibility. In order to improve its measurement technique, we built a system performing the calculation of the cross-correlation function of Doppler velocity signals. In 12 normal subjects and 10 patients, the mean difference between duplicate measurements was 0.7+/-7.8% (NS). We tested this technique in 15 elderly volunteers before and after a three months training period. Brachial and tibial systolic blood pressure decreased respectively from 18.1+/-2.2 kPa to 16.7+/-1.9 kPa (p=0.008) and from 21.1+/-3.4 kPa to 18.4+/-2.5 kPa (p=0.003), while lower limb PWV decreased from 8.96+/-1.26 to 7.92+/-1.22 m/s (p=0.016). Therefore, automatic PWV measurement using the cross-correlation technique allows to demonstrate training induced changes in PWV, although concomitant changes in blood pressure must be considered in their interpretation.
