摘要

This case describes an atypical presentation of isolated posterior ST-segment elevation myocardial infarction (STEMI), who presented with left arm numbness and weakness, mimicking an acute stroke. Diagnosis was confirmed with coronary angiogram showing occlusion in proximal left circumflex artery, as well as rise in troponin. This atypical presentation highlights the importance of maintaining high index of suspicion and casting a wide net of differential diagnoses in initial assessment of patient in the emergency department.
