Autonomic impairment in carotid stenosis may signal prognostic risk; leaves open whether BRS/HRV modification alters outcomes in prospective studies.
Does carotid stenosis impair baroreflex sensitivity and heart rate variability in patients with prior TIA or minor stroke compared to healthy controls?
Significant carotid stenosis is associated with impaired baroreflex sensitivity and heart rate variability, indicating autonomic dysfunction that may have prognostic implications for cardiovascular events.
