to determine the level of sympathoadrenal activation in the very early phase of acute myocardial infarction ( ami ) and to determine if location of infarction ( anterior versus inferior ) was related to sympathoadrenal activation , we studied norepinephrine ( ne ) and epinephrine ( e ) within 4 hours after the onset of symptoms and prior to any rise in plasma creatine kinase ( ck ) .
