Takotsubo cardiomyopathy (TTC) is an increasingly recognized, reversible cardiomyopathy with a clinical presentation that mimics an acute coronary syndrome but without evidence of obstructive coronary lesions. Typical presentation involves chest pain and/or dyspnea, transient ST-segment elevation on the electrocardiogram, and a modest increase in cardiac troponin. Cardiac imaging demonstrates wall-motion abnormalities that extend beyond the territory of a single epicardial coronary artery, and the absence of obstructive coronary lesions. Supportive treatment leads to spontaneous, rapid recovery of ventricular function, but about 10% of patients have recurrent events. This article reviews the defining features and clinical profile of TTC.
