Alpha-adrenoceptor stimulation with exogenous norepinephrine or release of endogenous catecholamines mimics ischemic preconditioning.

Abstract

Exposure of the heart to either transient exogenous norepinephrine or endogenous release of norepinephrine and/or other catecholamines by tyramine can mimic the effects of ischemic preconditioning in rabbits.
