title: [Determination of the aortic pulse wave velocity in 545 healthy subjects].
abstract: OBJECTIVE
  To understand the aortic pulse wave velocity (PWV) in mid-aged and elderly populations and to study the correlation between gender and PWV and the tendency of PWV on different age groups.
  
  
  METHODS
  According to the clinical trial guideline, we selected 545 healthy subjects (age, 31-85 years, 395 men and 150 women), and measured carotid-femoral PWV, using Complior.
  
  
  RESULTS
  The average value of PWV in Chinese healthy subjects was 11.62 +/- 2.97 m/s. There was no significant difference in the PWV values between males and females who were older than 40 years, but the values of PWV were lower in females than in males in the 30-39 year-old group. PWV was positively correlated with age. In the present study, the reference values of PWV were established in the different age groups, based on the regression equations between PWV and age.
  
  
  CONCLUSIONS
  Aortic pulse wave velocity seemed to be influenced by age but hardly influenced by gender in healthy subjects, so that the reference value of PWV should be established according to the different age groups. When aorta got stiffer, the value PWV got larger accordingly when age was increasing.
