Normalization of the norepinephrine kinetic response to orthostatic stress after cardiac transplantation

In summary, we have demonstrated through the use of forearm venous NE kinetic methodology that plasma NE and NE spillover increase normally in response to orthostatic stress after cardiac transplantation. These findings suggest that, in the absence of ventricular afferents, systemic arterial baroreflexes respond in a compensatory manner to activate the sympathetic nervous system.
