Tako-Tsubo cardiomyopathy is still en entity of unknown etiology and pathophysiology which clinically manifests with sudden, severe chest pain and/or dyspnea. It is generally triggered by emotional or physical stress and most cases are reported in postmenopausal women. Electrocardiographic changes are similar to acute myocardial infarction with ST-elevation, laboratory markers of myocardial lesion are usually mild to moderately high, and coronary angiography shows no significant pathomorphological changes of epicardial coronary arteries. Ventriculography and echocardiography show reversible akinesis and ballooning of the left ventricular apex with reduced ejection fraction which is usually normalized within 2-4 weeks. Generally, Tako-Tsubo cardiomyopathy has a good prognosis, in-hospital mortality rate is about 1%. In this article, we present a review about todays knowledge on Tako-Tsubo cardiomyopathy.
