Aortic Aneurysm Mimicking Inferior ST-Elevation Myocardial Infarction: A Case Report.

Here, we report a rare case of a 22-year-old female presenting with recurrent chest pain mimicking inferior ST-elevation myocardial infarction (STEMI) but ultimately attributed to an aortic aneurysm. Despite facing initial challenges in diagnosis, such as normal troponin levels and temporary electrocardiogram (ECG) changes, advanced imaging showed a large mass in the chest pressing on the right coronary artery. Prompt multidisciplinary intervention, including surgical resection of the aneurysm, led to successful management and improved outcomes.
