Myopericarditis as a Presenting Feature of Acute Myeloid Leukemia.

BACKGROUND

Myocarditis is a rare sequelae of acute myeloid leukemia (AML) and typically presents after the initial diagnosis of AML has been made.

CASE REPORT

We present the case of a 37-year-old female who came to the emergency department with chest pain, ST elevations on electrocardiogram, and a positive point-of-care troponin. She was brought emergently to the cardiac catheterization laboratory. After a negative catheterization, blasts were noted on the complete blood count, ultimately leading to the diagnosis of AML, with myopericarditis as the presenting manifestation. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: This case highlights the need for emergency physicians to consider a broad differential for chest pain, especially in those who do not fit into the prototypical patient with acute coronary syndrome.
