Abstract
Kounis syndrome defined as the appearance of acute coronary syndrome in the context of an allergic reaction is a relatively rare phenomenon. There are three variants of this syndrome in which the patient presents with symptoms of an acute chest. Herein, we describe a case of an 83-year-old woman who demonstrated type I variant of Kounis syndrome in response to vancomycin administration. After initialisation of vancomycin, she became unresponsive and an ECG demonstrated ST changes consistent with inferior-lateral myocardial infarction. Once allergic stimulus was removed, ECG normalised. Differential diagnosis includes, myocardial infarctions, angina as well as intravascular stent thrombosis, which must all be ruled out. The patient was monitored and discharged soon thereafter.
