Implicates endogenous catecholamines in myocardial stunning; hypothesis-generating for beta-blockade effects in clinical ischemia-reperfusion.
Does elimination of endogenous catecholamines improve tension recovery in a simulated ischemia model of ferret papillary muscles?
Endogenous catecholamines released during ischemia exacerbate myocardial stunning, which may limit the protective ability of beta-adrenergic antagonists.
Ishiguro et al. (2001) studied this question.
