Gemella Endocarditis Presenting as an ST-Segment-Elevation Myocardial Infarction

Abstract

Acute myocardial infarction from septic embolization is a rare initial presentation of endocarditis. We report the case of a 67-year-old man who presented with acute chest pain, in whom emergency cardiac catheterization revealed findings that suggested coronary embolism. The patient was found to have Gemella endocarditis, with its initial presentation an embolic acute ST-segment-elevation myocardial infarction. We suggest that endocarditis be considered among the potential causes of acute myocardial infarction.

Keywords: Coronary occlusion/microbiology; Gemella infections/complications; diagnosis, differential; embolism/complications/etiology; endocarditis, bacterial/complications/diagnosis/therapy; fatal outcome; myocardial infarction/etiology.
