RAU, Carlos M et al. Tako-Tsubo syndrome: Report of one case. Rev. méd. Chile [online]. 2011, vol.139, n.3, pp. 348-352. ISSN 0034-9887.  doi: 10.4067/S0034-98872011000300010.

Tako-Tsubo syndrome resembles an acute myocardial infarction in symptoms, laboratory parameters and electrocardiographic changes. However, angiography does not show evidence of coronary occlusion, and typically an apical ballooning ofthe ventricle in systole is observed. We report a 78-year-old woman with no coronary risks factors, admitted to the emergency room due to acute chestpain and an electrocardiogram compatible with an acute coronary syndrome with ST elevation. Serum troponin and creatin-kinase (MB fraction) were elevated. An emergency coronary angiography did not show a coronary occlusion. Due to the apical ballooning observed in the left ventriculography, aprobable diagnosis of Tako-Tsubo was proposed. The patient had a favorable evolution. A treadmill test, echocardiogram and myocardial perfusión SPECT, performed one month later, disclosed no abnormalities.
