A huge coronary artery aneurysm with ST-elevation myocardial infarction: A case report and review of literature

<h2>Abstract</h2><h3>Background</h3> Giant coronary artery aneurysms (GCAA), are rare findings often discovered incidentally in adults. GCAAs are defined by a significant enlargement of coronary arteries, posing a heightened risk of myocardial infarction and thrombosis. <h3>Case presentation</h3> A 52-year-old male known case of ischemic heart disease (IHD), presented with chest pain and signs of anterior ST-elevation MI (STEMI). He had a history of MI six years ago and was on a medical regimen. Coronary angiography revealed a huge aneurysm (4.8∗8.2mm) in the left anterior descending artery (LAD) and ectasia in other arteries. Surgical management via coronary artery bypass graft (CABG) was pursued, successfully addressing the aneurysm. <h3>Conclusion</h3> Recent advancements have improved our understanding and imaging capabilities for coronary artery aneurysms (CAAs). Treatment options include medical therapy, percutaneous coronary intervention, or surgery, with decisions tailored to individual cases. Standardized treatment protocols await clarification through further research, including randomized controlled trials.
