Key result
Arterial path length measurements accounting for carotid arterial length yielded absolute pulse wave velocity values 16-31% lower than those calculated using the straight distance between carotid and femoral sites.
Why the study?
How do different body surface measurements for arterial path length affect absolute carotid-femoral pulse wave velocity values in healthy adults?
Population
250 apparently healthy adults (127 men, 123 women, aged 19-79 years) free of overt cardiovascular disease.
Design
Cross-sectional

PWV interpretation requires caution given path length variability; leaves open optimal standardization before broader clinical or research adoption.

How do different body surface measurements for arterial path length affect absolute carotid-femoral pulse wave velocity values in healthy adults?
Effect estimate: 16-31% lower
p-value: p=<0.0001
Different body surface measurements used to estimate arterial path length produce substantial variations in absolute PWV values, highlighting an urgent need for methodological standardization.
Sugawara et al. (2009) conducted a cross-sectional in Apparently healthy adults (n=250). Arterial path length measurements accounting for carotid arterial length vs. Straight distance between carotid and femoral sites was evaluated on Carotid-femoral pulse wave velocity (PWV) (16-31% lower, p=<0.0001). Arterial path length measurements accounting for carotid arterial length yielded absolute pulse wave velocity values 16-31% lower than those calculated using the straight distance between carotid and femoral sites.
