Assessment of first derivative of doppler blood flow velocity in vascular aging

The aim of this study is to determine the first derivative of blood flow velocity (FDBFV) in common carotid artery (CCA) in order to evaluate cardiovascular functions. The extracted derivative of the velocity is suggested the acceleration waves which able to provide an aging index (AGI) in the cardi...
