[Tako-Tsubo syndrome in a patient with exacerbated bronchial asthma].

Transient apical ballooning syndrome without coronary stenosis or Tako-Tsubo syndrome was described a few years ago in a Japanese population. Although new cases and series have been gradually defining its physiopathology, there is much doubt about its etiology. We describe the case of a 74-year-old Caucasian woman, with a background of hypertension, type 2 diabetes mellitus and hyperthyroidism with tracheal compression, intrinsic asthma and depression syndrome. She had an acute attack of bronchospasm and chest pain. The electrocardiogram on admission showed Q-waves and ST segment elevation in precordial leads and elevated serum cardiac markers. The coronariography found no evidence of significant lesions in the vascular tree. Ventriculography showed an apical ballooning that was also found in the echocardiography. The evolution of the clinical picture with disappearance of the symptoms and normalization of the electrocardiogram and echocardiogram lead to the diagnosis of Tako-Tsubo syndrome. We believe that this new clinical entity may have a catecholamine-mediated neurogenic mechanism as the etiopathogenic substrate and that our clinical case could support this hypothesis.
