[Determination of the aortic pulse wave velocity in 545 healthy subjects].

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.

[Clinical study of the distensibility of large arteries in elderly patients with essential hypertension].

Objective: To explore the change in the distensibility of large arteries and its influencing factors in elderly patients with essential hypertension.

Methods: Automatic measuring system for pulse wave velocity (PWV) was applied to examine carotid-femoral PWV as an index reflecting distensibility of large arteries. 118 hypertensive patients aged 64 - 83 (mean age 67.
