Acute MCA velocity rise after smoking should not change practice; hypothesis-generating for cerebral autoregulation effects.
Observational (n=14)
Does smoking acutely increase middle cerebral artery flow velocity in healthy subjects?
Smoking acutely increases middle cerebral artery flow velocity, potentially reflecting a global increase in cerebral blood flow via complex influences on cerebral autoregulation.
Boyajian et al. (2000) conducted an observational in Healthy subjects (n=14). Smoking vs. Baseline (before smoking) was evaluated on Middle cerebral artery (MCA) mean flow velocity. Smoking acutely increased middle cerebral artery mean flow velocity by a group mean of 19% (range 2-64%) in healthy subjects.
