Sympathetic neck blockade may restore cerebral blood flow velocity during exercise under beta-1 blockade; leaves open whether targeted sympathetic modulation improves outcomes in limited cardiac output states.
Does unilateral stellate ganglion blockade affect the attenuation of middle cerebral artery blood velocity during exercise induced by beta-1 adrenergic blockade in humans?
A reduced ability to increase cardiac output during exercise limits cerebral blood flow, a limitation that is likely mediated by the sympathetic nervous system.
