Abstract:
Various neurological disorders and emotional stress may cause left ventricular dysfunction, known as a neurogenic stunned myocardium. A previously healthy 71-year-old woman collapsed immediately after experiencing left arm numbness and pain. Thereafter, the patient complained of anterior chest pain and became comatose. An electrocardiogram showed ST-segment elevation of I, aVL, and V2-3 and depression of II, III, and aVF. Echocardiography revealed anteroseptal hypokinesis of the left ventricle. Emergency coronary angiography revealed no significant stenosis in the coronary arteries; however, left ventriculography revealed obvious anteroseptal hypokinesis. When the patient regained consciousness the following day, tetraplegia was observed. Spinal computed tomography and magnetic resonance imaging revealed an intramedullary spinal cord hemorrhage from the medulla to the conus. The cardiac function recovered, but the patient remained tetraplegic with poor spontaneous respiration. Although its incidence is extremely rare, hematomyelia should be recognized as a potential cause of neurogenic stunned myocardium.
