Elevated Hemi-diaphragms as a Cause of ST-segment Elevation: A case report and review of literature

While ST-segment elevation (STE) on ECG is widely recognized as representing myocardial infarction or injury such as coronary occlusion or pericarditis, STE may occasionally ensue from non-cardiac etiologies. Indeed, gastrointestinal disorders causing STE are not well documented in the literature. We present a case wherein extreme abdominal distension and hemi-diaphragm elevation resulted in extrinsic cardiac and epicardial coronary compression manifesting as STE. Subsequent relief of the abdominal distension resulted in resolution of STE representing a noncoronary cause of STE. A brief literature review, illustrating the importance of considering abdominal etiologies as a cause of STE is provided.
