RESUMO
The authors report the case of 2-old-caucasian women in the pre- and interhospital setting, who presented chest pain with ST segment elevation. Coronary angiography did not show any significant coronary lesion, ventriculography revealed typical aspect of tako-tsubo. It resolved in a short time, with normalisation of the left ventricule function. The tako-tsubo syndrome, or transient left ventricular apical ballooning syndrome, first described by Japanese physicians, is more and more frequently observed in caucasian patients. This cardiomyopathy associates an apical transient dysfunction without any significant coronary lesion. This syndrome is usually observed in elderly women, occurs frequently after acute emotional or physical stress. The clinical presentation looks like an acute coronary syndrome, with chest pain, electrocardiographic changes and moderate cardiac enzymes release. Coronary angiography shows no significant coronary disease and ventriculography a systolic dysfunction with akinesia of middle and apical segments, leading apical ballooning, and basale hyperkinesia. These abnormalities are transient, with quick favorable outcome. The aetiopathegenia is still uncertain. The differential diagnosis with an acute coronary syndrome with thrombosis is not yet possible. Clinical or biological criteria allowing early diagnosis would lead to optimize the therapeutic management.
