title: Acute myocardial infarction after administration of low-dose intravenous epinephrine for anaphylaxis.
abstract: This case describes a 29-year-old woman who presented with an acute severe anaphylactic reaction to penicillin. In addition to other medications administered in the emergency department, she received 0.1 mg intravenously of 1:10 000 epinephrine, after which she immediately developed severe chest pain. Her ECG showed ST elevations consistent with an anterior myocardial infarction, and her serum troponin level was elevated. A CT angiogram showed no signs of coronary artery disease or abnormal anatomy. This case is an example of vasospasm-induced myocardial injury and illustrates a potential danger of intravenous epinephrine use. The authors were able to identify only 2 other case reports where therapeutic doses of epinephrine have been reported to cause this phenomenon.
