Abstract
Tako-tsubo, or stress cardiomyopathy is an increasingly recognized type of primary acquired cardiomyopathy occurring commonly after a recent stressful event and characterized by transient myocardial systolic dysfunction that is mainly confined to the apical region of the left ventricle. The clinical presentation closely resembles that of an acute coronary syndrome, with chest pain, ischemic type ST-segment changes and minimal cardiac enzyme elevation. Prognosis is good, with full recovery of cardiac function within 2-4 weeks in most of the cases. Treatment is supportive but coronary angiography is necessary to establish the diagnosis. The pathogenetic mechanism remains currently unknown, although catecholamine surge definitely plays a primary role.
