A case of blunt chest trauma induced acute myocardial infarction involving two vessels.

Blunt chest trauma rarely induces acute myocardial infarction. We report a 36-year-old man who suffered from blunt trauma to the anterior chest wall while operating a punching machine. This case is the first report of simultaneous blunt chest trauma to the left anterior descending artery and left circumflex artery. The patient was treated surgically and discharged without any serious sequela. Early detection of the lesion site is important with regard to selecting the appropriate treatment strategy in patients with coronary injury caused by blunt chest trauma. Routine 12-lead electrocardiography and serial cardiac enzyme evaluation are necessary in every patient with chest trauma because they supply crucial information about the extent of cardiac damage. Treatment with primary angioplasty or bypass surgery should be based on the characteristics of the lesion and the associated problem.
