[Takotsubo syndrome and multivessel coronary disease]

Takotsubo syndrome is a generally reversible cardiomyopathy often related to a stressor trigger, either physical or emotional. It is estimated that this entity represents between 1 and 6% of the cases of suspected acute coronary syndrome without ST segment elevation in women. Coexistence with coronary artery disease has been a matter of long controversy. On this matter, we present the clinical case of a 79-year-old hypertensive and dyslipidemic female with smocking history, who was referred to our institution presenting an episode of chest pain with anginal characteristics. During the conducted interrogation, she reported having been overpassing a stressfull moment in her private life. The electrocardiogram showed deep and diffuse negative T waves with prolonged QT interval. Laboratory findings revealed dissociation of biomarkers (troponin/ProBNP), and the transthoracic Doppler echocardiogram showed left ventricular dysfunction with apical ballooning. Given the differential diagnoses of acute coronary syndrome and TakoTsubo syndrome, a coronary angiography was performed, which revealed multiple epicardial coronary disease. However, due to the strong suspicion of stress cardiomyopathy, a cardiac magnetic resonance imaging with gadolinium was performed, which showed an improvement in the ejection fraction prior to revascularization with the presence of myocardial edema and absence of late gadolinium enhancement. The aforementioned characteristics led to the diagnosis of Takotsubo syndrome. The final decision of revascularization was based on the fact that the patient's principal complaint was typical anginal symptoms.
