to elucidate the role played by catecholamines in the early phase of ischemic derangement of the myocardial energy metabolism , effects of beta-blockers ( propranolol , pindolol , and celiprolol ) and isoproterenol , and of pretreatment with reserpine and 6-hydroxydopamine ( 6-ohda ) , were studied using the isolated perfused rat heart . beta-blockers and isoproterenol were infused for 12 min prior to induction of global ischemia .
