Relations between carotid artery distensibility and heart rate variability The Cardiovascular Risk in Young Finns Study

Reduction in carotid artery wall elasticity may interfere with baroreceptor function that could lead to low vagal tone. We studied at the population level the relations between carotid-artery-distensibility (Cdist) and vagal modulation of heart rate. Cdist was assessed with ultrasonic measurements o...

Description
Summary:Reduction in carotid artery wall elasticity may interfere with baroreceptor function that could lead to low vagal tone. We studied at the population level the relations between carotid-artery-distensibility (Cdist) and vagal modulation of heart rate. Cdist was assessed with ultrasonic measurements of changes in carotid artery diameter during cardiac-cycle. Vagal tone was estimated with the heart rate variability (HRV) in 1872 healthy 24-39year-old subjects. Cdist was significantly related with all HRV-components (always P
