Acute Myocardial Infarction Following Blunt Thoracic Trauma in a Young Patient

Introduction Coronary artery dissection caused by trauma is a rare but serious condition that can lead to acute coronary syndrome. The dissection may result from various mechanisms, including thrombus formation and intramural hematoma, leading to intraluminal occlusion. This report presents a case of acute myocardial infarction secondary to right coronary artery dissection in a traumatic context. Case Presentation We report the case of a 30-year-old male patient who presented to the emergency department with constrictive chest pain after sustaining direct blunt thoracic trauma caused by a pig. Clinical and imaging findings were suggestive of an acute coronary event. Coronary angiography and optical coherence tomography confirmed an acute occlusion of the right coronary artery due to dissection with intramural hematoma. A drug-eluting stent was placed to restore vessel patency. The patient had a favorable outcome, with improved ventricular function at discharge compared to admission. Conclusion Although uncommon, coronary artery dissection should be considered in patients presenting with acute chest pain following thoracic trauma. Prompt diagnosis and timely interventional treatment are essential to improving prognosis and minimizing long-term impairment of ventricular function.
