Subjects: Japanese adults >= 34 years of age
The index may range from about 1,000 cm/s at the lower end of normal range for a 35 year old to 2,000 for the upper limit of normal for an 80 year old.
Factors affecting baPWV index:
(1) The PWV index tended to increase with age.
(2) Males tend to have a higher PWV index than females.
(3) Regular ethanol use was associated with a lower PWV index.
Parameters:
(1) age in years
(2) mean arterial pressure (MAP) in mm Hg
(3) heart rate in beats per minute
(4) gender
equation for mean baPWV in cm/sec =
= (0.21 * ((age)^2)) – (13.73 * (age)) + (0.05 * ((MAP)^2)) + (3.95 * (heart rate)) + (36.49 if male, 0 if female) + 733
equation for upper limit of normal baPWV in cm/sec =
= (0.22 * ((age)^2)) – (14.22 * (age)) + (0.05 * ((MAP)^2)) – (0.76 * (MAP)) + (4 * (heart rate)) + (37.26 if male, 0 if female) + 1100
