Abstract

This Points to Remember column discusses the differential diagnosis of acute myocardial infarction with normal coronary arteries, one example of which is Takotsubo cardiomyopathy. In the case presented below, the diagnosis of Takotsubo cardiomyopathy was based on the characteristic appearance of the left ventricular apical bulging, normal coronary arteries, and the resolution of the wall motion abnormalities within a relatively short period of time.

Keywords: Takotsubo cardiomyopathy; broken heart syndrome; intramyocardial small vessel disease; stress cardiomyopathy.
