Bruehl S, et al. - In view of the observation that heart rate variability (HRV) and baroreflex sensitivity (BRS) reflect the ability to maintain cardiovascular homeostasis amidst changing conditions, individuals with chronic pain (CP) (broadly defined) were compared with pain-free controls in terms of HRV and BRS. Findings confirmed a link between the presence of CP and impaired cardiovascular regulation. This study supported that links between CP and comorbid hypertension reported in previous population studies could be due in part to CP-related decrements in cardiovascular regulation.
