AbstractTakotsubo cardiomyopathy, also called "broken heart" syndrome or apical ballooning syndrome, is a reversible cardiomyopathy characterized by left ventricular dysfunction and ballooning of the left ventricular apex on imaging during systole. It predominantly occurs in post-menopausal women and is commonly associated with emotional or physical stress. Patients commonly present with chest pain and electrocardiographic evidence of ST segment elevation or T-wave-mimicking acute coronary syndrome, but with an absence of angiographic evidence of obstructive coronary disease. The exact cause is unknown, but potential contributors include catecholamine excess and sympathetic nervous system hyperactivity. There is no consensus on pharmacological treatment of takotsubo cardiomyopathy. Based on the suspected pathophysiology of the disease, adrenergic blockade using beta-blocker therapy is employed. Near complete resolution of left ventricular wall motion dyskinesis occurs in the majority of takotsubo cardiomyopathy patients within a month. Although the prognosis is generally favorable, there are reports of complications during the acute phase, including cardiogenic shock, pulmonary edema, ventricular tachycardia, apical thrombus formation, and death. This review article will briefly discuss the epidemiology, etiology, clinical features, diagnostic evaluation, and treatment of this condition.
