Takotsubo cardiomyopathy or stress-induced cardiomyopathy is often diagnosed as an acute coronary syndrome in postmenopausal women, because its clinical presentation may mimic an acute myocardial infarction: anginal chest pain, changes in the ST segment and T wave in precordial leads and elevated cardiac biomarkers of necrosis. It is characterized by systolic dysfunction with transient ballooning of the apical and middle portions of the left ventricle, in the absence of significant coronary disease. Prognosis is good and complete recovery occurs in days to weeks. We report three cases of postmenopausal women with initial diagnosis of acute myocardial infarction; no significant coronary lesions were found in the coronary angiography; apical ballooning, characteristic of this syndrome, was observed on left ventriculography. On follow-up, the three patients had complete recovery of systolic function at six weeks. KEYWORDS: Acute Coronary Syndrome; Acute Heart Failure,Tahotsubo Cardiomyopathy La cardiomiopatia de Takotsubo o cardiopatia por estres se diagnostica frecuentemente como un sindrome coronario agudo en mujeres posmenopausicas, por su presentacion clinica, que puede simular un infarto agudo de miocardio: dolor toracico anginoso, cambios del segmento ST y de la onda T en las derivaciones precordiales y elevacion de biomarcadores cardiacos de necrosis. Se caracteriza por disfuncion sistolica con discinesia transitoria de los segmentos apicales y/o medios del ventriculo izquierdo, en ausencia de enfermedad coronaria significativa. Tiene buen pronostico y la recuperacion ocurre en dias a semanas. Describimos los casos de tres mujeres posmenopausicas con diagnostico inicial de infarto agudo de miocardio. En la coronariografia no se encontraron lesiones significativas, y en la ventriculografia se observo el abalonamiento apical y medial, que es caracteristico de este sindrome. En todos los casos hubo recuperacion completa de la funcion sistolica a las seis semanas de seguimiento.
