    Abstract:
    A 32-year-old white male police officer suffered blunt trauma to the anterior chest wall during a routine training session. This was accompanied by the precipitous onset of chest discomfort. There was no previous history of any cardiac risk factors. The diagnosis of an inferior wall myocardial infarction was made based on the electrocardiogram findings, at his local community hospital. The total creatine kinase, creatine kinase-MB, and troponin I were normal. The transesophageal echocardiogram performed at that time demonstrated no aortic or coronary dissection. He was transferred to our tertiary care center. Emergency cardiac catheterization demonstrated lateral wall hypokinesis with a left ventricular ejection fraction of 45% and a total occlusion of the left circumflex coronary artery in its proximal portion. This was successfully recannulized with angioplasty and stenting techniques. We believe this to be only the second reported case of circumflex coronary artery obstruction after blunt chest trauma.
