Association between Carotid Intima Media Thickness and Heart Rate Variability in Adults at Increased Cardiovascular Risk.

Atherosclerotic carotid intima-media thickness (IMT) may be associated with alterations in the sensitivity of carotid baroreceptors. The aim of this study was to investigate the association between carotid IMT and the autonomic modulation of heart rate variability (HRV). A total of 101 subjects were enrolled in this prospective observational study.
