Diminished carotid bulb distensibility and flow separation with age may modify local atherogenesis risk; cross-sectional data leaves open predictive value for events.
How do flow velocity patterns and distensibility of the carotid artery bulb differ between younger and older subjects?
Older age is associated with diminished distensibility and reduced flow separation and recirculation in the carotid artery bulb.
Reneman et al. (1985) studied this question.
