This syndrome usually occurs in women and is frequently associated with an intense emotional or physical stress. It usually involves apical segments,but in the recent years atypical forms have been described. Inverted or reverse Takotsubo is a variant in which the basal and midventricular segments are hypokinetic,sparing contractile function of the apex. In this report we describe the case of a 54-year-old woman,with chronic malnutrition,initially admitted because of hypoglycemia and severe electrolyte disturbance due to a refeeding syndrome. Within the next hours she experienced acute cardiac symptoms and developed heart failure with low cardiac output. Electrocardiogram(ECG),elevation of troponin and echocardiographic findings were consistent with inverted Takotsubo cardiomyopathy. To the best of our knowledge,this is the first incidence reported of inverted Takotsubo triggered by refeeding syndrome.展开更多
