Overview

Observational analysis shows cardiac sympathetic activity influences cerebral blood flow regulation in post-stroke patients, indicating neurovascular connections exist.

Key Points

  • Maladaptive crosstalk likely exists between cardiac rhythms and cerebral autoregulation.
  • Elevated mean flow velocity was associated with cardiac sympathetic changes in stroke and elderly populations.
  • Transcranial Doppler assessed blood flow dynamics during orthostatic stress via mean flow velocity measurements.
  • Findings emphasize the importance of understanding the interplay in neurovascular dynamics in ageing populations.,
