Sympathovagal imbalance in early ischemic stroke is linked to impaired cerebral autoregulation and increased infarct volumes

Autonomic dysfunction is associated with worse outcome of ischemic stroke patients by mechanisms that are not fully understood. There is evidence of autonomic influence in cerebrovascular control but this has not been studied in acute stroke. Therefore, we examined the relationship between heart rate variability (HRV) and baroreflex sensitivity (BRS) in dynamic cerebral autoregulation in the early hours post ischemia, and its impact in clinical and radiological outcome.
