A serious clinical course of a very elderly patient with takotsubo cardiomyopathy.

An 86-year-old woman was admitted to our hospital because of vomiting and anorexia. Although serum cardiac markers, an electrocardiogram, and echocardiography suggested acute myocardial infarction, emergency cardiac catheterization revealed akinesis of the left ventricular apex without significant coronary artery stenosis. She was diagnosed as having takotsubo cardiomyopathy. The left ventricular dysfunction was considered transient and reversible but did not improve at all, contrary to our expectations. She died of worsening heart failure on day 14. We discuss this serious clinical course of a very elderly patient with takotsubo cardiomyopathy.
