Abstract：To investigate the correlation among pulse wave velocity (PWV), radial augmentation index (AIr) and diastolic
augmentation index (AId) and their influencing factors, we selected 133 health subjects to measure the pressure waveforms of
the carotid and femoral artery by using the SphygmoCor Px pulse waveform analysis system (AtCor, Australia). The radial artery
waveforms were collected by BL-420S Data Acquisition & Analysis System (China Pacific Technology Co., Ltd.). Then the
waveform was denoised and some feature parameters such as PWV, AIr and AId were calculated. There was significant correlation
between cf-PWV and AIr (R=0.5195, P<0.001), and cf-PWV was not significantly correlated with AId (R=-0.1472, P=0.0908). Heart
rate is the common influence factor of AIr and AId.
