STEMI mimicker in a 26-year-old man.

We herein describe a case of acute myocarditis which may mimic myocardial infarction, since affected patients experience 'typical' chest pain, the ECG changes are identical to those observed in acute coronary syndromes, and serum markers are increased. This case emphasises the importance of performing appropriate cardiac MRI to help in the differential and definitive diagnosis as well as the extent of myocardial involvement. ST elevation myocardial infarction is rare in young adults and when it is encountered, it should raise the differential diagnosis of its mimickers. © BMJ Publishing Group Limited 2019.
