  • Title: Acute myocardial infarction due to left anterior descending coronary artery dissection after blunt chest trauma.
    Author: Oghlakian G, Maldjian P, Kaluski E, Saric M.
    Journal: Emerg Radiol; 2010 Mar; 17(2):149-51. PubMed ID: 19214607.
    Abstract:
    Cardiac complications of chest trauma range from arrhythmias to valvular avulsions to myocardial contusion, rupture, and rarely myocardial infarction. We describe a case of a young patient with blunt chest trauma after a motor vehicle accident in whom the diagnosis of myocardial infarction was established a week later because no electrocardiogram or cardiac biomarkers were obtained on presentation. Retrospective review of contrast-enhanced computed tomography (CT) of the chest done on presentation demonstrated a perfusion defect in the distribution of the left anterior descending artery (LAD). Subsequent coronary angiography demonstrated dissection in the proximal LAD. Our case illustrates the importance of electrocardiography and contrast-enhanced chest CT in initial evaluation of patients with blunt chest trauma and suspected injury to the coronary arteries.
