Coincident Takotsubo Cardiomyopathy and Coronary Artery Disease / 대한내과학회지

ABSTRACT

Takotsubo cardiomyopathy is characterized clinically by transient left ventricular dysfunction in patients with normal coronary angiography findings. We report a case of Takotsubo cardiomyopathy with significant stenosis on coronary angiography. A 71-year-old woman was admitted to our hospital in a drowsy mental state. She was suspected to have diabetic ketoacidosis, but cardiac enzyme levels and electrocardiogram results were typical of myocardial infarction. Coronary angiography revealed occlusion of the distal right coronary artery. Echocardiography and left ventriculography revealed reduced left ventricular function with apical ballooning. However, coronary artery stenosis did not explain the severe reduction in left ventricular function. After 11 days, her left ventricular function and electrocardiogram results had returned to normal. Therefore, coronary artery disease does not rule out the presence of Takotsubo cardiomyopathy.
