  Abstract

A 70-year-old female experienced severe anxiety due to an incident with a stranger when she was home alone at night. Immediately after the event, she had an oppressive chest sensation; 16h later she was admitted to hospital. Left ventriculography showed akinesia of the mid-to-distal portion and hyperkinesia of the basal portion of the left ventricular chamber. However, coronary angiography showed no significant coronary artery disease. We diagnosed her as having Tako-Tsubo cardiomyopathy. Subsequently, left ventricular and central aortic pressures were recorded simultaneously. Initial recording showed a peak systolic gradient of 60mm Hg. On the first sinus beat after a premature ventricular contraction, the peak systolic gradient increased to 130mm Hg, and the pulse pressure decreased. Shortly after intravenous administration of nitroglycerin (0.5mg), central aortic pressure decreased and the peak systolic gradient increased to 100mm Hg. On the first sinus beat after a premature ventricular contraction, the peak systolic gradient increased to 160mm Hg, and the pulse pressure decreased. Five minutes after intravenous nitroglycerin, the peak systolic gradient returned to 70mm Hg. Follow-up transthoracic echocardiography 13days later showed normal left ventricular wall motion with no pressure gradient through the left ventricular outflow tract.
