Key result
Aging up to 50 years is linked to declining carotid compliance, followed by a plateau.
Why the study?
Age-related changes in carotid artery compliance and sex differences in compliance were not fully characterized across a wide age range in asymptomatic individuals.
Cross-Sectional (n=658)
Arterial compliance changes should not yet guide clinical decisions; leaves open their role in age- and sex-specific risk prediction.
Doppler-shifted ultrasound was used to measure arterial compliance non-invasively in the internal and external carotid pathways of 270 male and 388 female asymptomatic volunteers aged 5 to 90 years. There was a significant decrease in the compliance of both arteries from 5 to 50 years of age (p less than 0.001), when it then levelled out. Arteries of women were more compliant than those of men at ages 35 to 60 years.

BASKETT et al. (1990) conducted a cross-sectional in Asymptomatic volunteers (n=658). Age was evaluated on Arterial compliance in the internal and external carotid pathways (p=<0.001). Aging from 5 to 50 years was associated with a significant decrease in arterial compliance of both internal and external carotid pathways (p<0.001), after which it leveled out.
