“…5 Takotsubo-the Japanese term for "octopus pot," which describes the apical ballooning morphology of the LVwas coined by Sato and associates in 1990. 6 This disease accounts for approximately 2% of all cases of suspected MI, and cases predominantly occur in postmenopausal Asian or white women.…”

Takotsubo cardiomyopathy, or transient left ventricular apical ballooning syndrome, is characterized by acute left ventricular dysfunction caused by transient wall-motion abnormalities of the left ventricular apex and mid ventricle in the absence of obstructive coronary artery disease. Recurrent episodes are rare but have been reported, and several cases of takotsubo cardiomyopathy have been described in the presence of hyperthyroidism. We report the case of a 55-year-old woman who had recurrent takotsubo cardiomyopathy, documented by repeat coronary angiography and evaluations of left ventricular function, in the presence of recurrent hyperthyroidism related to Graves disease. After both episodes, the patient's left ventricular function returned to normal when her thyroid function normalized. These findings suggest a possible role of thyroid-hormone excess in the pathophysiology of some patients who have takotsubo cardiomyopathy.

“…Similar deep negative T waves are seen in subendocardial ischemia due to left anterior descending artery lesions [2], sometimes in subarachnoid hemorrhage [3], and in pheochromocytoma [4]. In addition to the clinical history, two-dimensional echocardiography (2DE) greatly contributes to the differentiation between these etiologies.…”

Deep negative T waves associated with reversible left ventricular dysfunction in acute adrenal crisis

We report two cases of reversible left ventricular dysfunction associated with deep negative T waves during acute adrenal crisis due to isolated deficiency of adrenocorticotrophic hormone. There were no symptoms suggestive of heart disease in either case and left ventricular wall motion abnormalities, present mainly around the left ventricular apex, returned to normal in 1-2 weeks. Deep negative T waves normalized 4 weeks after corticosteroid administration. Acute adrenal crisis should be considered when deep negative T waves are associated with left ventricular dysfunction without cardiac symptoms.

“…This pioneering work inspired other investigators, who discovered that LVEF and regional wall motion abnormalities were significant predictors of death in patients with subarachnoid hemorrhage (Sugimoto et al, 2008). Reversible left ventricular dysfunction induced by excessive catecholamine surges in pheochromocytoma was also reported (Iga et al, 1989). This finding suggested that catecholamines at high concentrations can directly damage the myocardium.…”
