Boerhaave syndrome: an unusual myocardial infarction mimic-a case report.

Background: A rare complication of oesophageal rupture or Boerhaave syndrome is myopericarditis due to leakage of oesophageal contents. This presentation can mimic a myocardial infarction, making diagnosis and management challenging. Case summary: We present the case of a middle-aged man presenting with chest pain, who was diagnosed with Boerhaave syndrome complicated by myopericarditis, although the presentation was concerning for acute coronary syndrome. Discussion: Through this case, we aim to highlight an unusual alternative aetiology of findings classically seen in myocardial infarction.
