Acute myocardial infarction due to coronary thrombosis caused by blunt chest trauma

A 65-year-old man presented to the emergency department following an anterior chest trauma. He had significant chest pain and chest X-ray was significant for revealed multiple rib fractures and negative. CT scan of the chest ruled out pulmonary embolism or aortic dissection. However, few hours later he developed hypotension requiring admission to medical intensive care unit and intravenous vasopressors. Further workup showed ST elevation myocardial infarction involving the anterior ECG leads. Emergent coronary angiography was performed with intervention to the mid-left anterior descending occlusion. Cardiogenic shock resolved and patient was discharged few days later. One-year follow-up with echocardiogram showed stable ischaemic cardiomyopathy with improved left ventricular ejection fraction to 50%.
