In stress cardiomyopathy (also known as apical ballooning, broken heart syndrome, or takotsubo cardiomyopathy) the left ventricle takes on the appearance of a Japanese octopus pot (tako tsubo). The syndrome has been linked to emotional distress (e.g., death of a spouse, near-drowning, smoke inhalation, and so on). Often presents with anterior ST-elevation and associated with a rise and fall of cardiac biomarkers (so meets the technical definition of acute myocardial infarction) although no artery is occluded.
