ST-segment elevation myocardial infarction with normal coronary arteries secondary to anterior communicating cerebral artery aneurysmal rupture: a case report.

Myocardial infarction with non-obstructive coronary arteries is uncommon. Though the majority is due to either plaque disruption or myocarditis, non-cardiac causes, such as acute neurological insults and substance use, should be considered. Scrutinizing the clinical presentation and using a meticulous approach with appropriate investigations are required to reach the correct diagnosis and appropriate management.
