Myocardial injury from blunt chest trauma can result from either direct contusion or coronary artery injury due to acute coronary syndrome or coronary dissection. Although rare, blunt chest trauma is one of the non-atherosclerotic mechanisms leading to acute myocardial infarction (MI) in patients younger than 45 years. We are reporting ...
