This report summarises the case of a 19-year-old male, with a history of gastro-oesophageal reflux disease, who presented to hospital with an acute chest pain. An electrocardiographic and biochemical diagnosis of ST elevation myocardial infarction was made; however, subsequent coronary angiography and echocardiography were both normal. In the week preceding the admission, the patient had consumed large quantities of a popular energy drink and the authors believe this may have implicated the development of his coronary event. This is an association that has been suggested previously and this report briefly summarises the evidence supporting the connection.
