    Abstract:
    The etiology of a novel cardiac syndrome called "tako-tsubo" cardiomyopathy, otherwise known as "acute onset and reversible left ventricular apical wall motion abnormality (ballooning)," is very similar to that of acute myocardial infarction; however, it may also be associated with emotional or physical stress. We report a case of tako-tsubo-like left ventricular dysfunction with ST-segment elevation after trauma. A 69-year-old man was transferred to our hospital after a fall in which he injured his back. He was diagnosed with a central spinal cord injury and was admitted to our Intensive Care Unit. He complained of a sudden chest pain 12 h after the injury. ST-segment elevation was observed on the electrocardiographic monitor, and subsequent 12-lead electrocardiogram demonstrated ST-segment elevation in leads V(2) through V(5). We considered acute myocardial infarction or cardiac contusion to be the cause of this event; therefore, an emergency coronary angiography was performed. However, the angiography revealed no significant coronary artery stenosis. Furthermore, left ventriculography demonstrated severe hypokinesis of the left ventricular apical region, consistent with tako-tsubo-like left ventricular dysfunction. The patient's cardiac function improved gradually, and he was discharged from our hospital on the 18(th) day after admission. Physicians should recognize the syndrome of tako-tsubo-like left ventricular dysfunction, which may result from traumatic stress or chest injury.
