Key result
Conservative medical therapy successfully treats blunt trauma-induced LMCA dissection and acute anterior MI.
Case Report (n=1)
Conservative medical therapy may be appropriate for stable patients with coronary artery dissection following blunt chest trauma.
May support conservative management in stable traumatic coronary dissection; hypothesis-generating for larger cohorts.
Coronary artery injury after blunt chest trauma is very rare, but this can result in a serious acute myocardial infarction. Coronary artery dissection is an uncommon complication of thoracic injuries. We report a case of a 17-year-old male who was presented with an anterior myocardial infarction following blunt chest trauma after a bicycle accident. His coronary angiography revealed aneurysmal dilatation with dissection of the distal left main stem coronary artery. Intravascular ultrasound showed a dissecting flap at the left main stem coronary artery. The patient was treated conservatively and discharged without serious sequelae. When symptoms and electrocardiographic findings are compatible with acute myocardial infarction, careful evaluation is important in patients with thoracic injuries for proper management. If the patient is stable, medical therapy may be appropriate. But early intervention should be considered in the presence of ongoing myocardial ischemia.

Chun et al. (1998) conducted a case report in Left main coronary artery dissection after blunt chest trauma presenting as acute anterior myocardial infarction (n=1). Conservative medical therapy was evaluated on Clinical outcome. Conservative medical therapy was successfully used to treat a 17-year-old male with left main coronary artery dissection and acute anterior myocardial infarction following blunt chest trauma.
