Disfunção ventricular esquerda transitória por cardiomiopatia induzida por estresse

Abstract

The case presented here is of a 71-yr-old female patient who met the diagnostic criteria for stress-induced cardiomyopathy, which was triggered by intense emotional stress after being hit by a bicycle. The clinical picture mimicked that of an acute myocardial infarction, manifesting as precordial pain, ST-segment depression followed by deep negative T waves and prolonging of the QT interval, slight increase in cardiac enzymes and coursing with transient apical ballooning of the left ventricle and hyperkinesis of the basal walls (conferring the aspect of "apical ballooning"), although in the absence of subepicardial coronary obstruction. Ventricular function normalized after the second week of clinical evolution.

“…Although its real prevalence has not been defined, retrospective surveys suggest that 2% of the cases treated as acute coronary syndrome are actually Takotsubo syndrome 5 .…”
