Myocardial perfusion scintigraphy during chest pain: An atypical presentation of takotsubo cardiomyopathy?

Although Takotsubo cardiomyopathy (TCM) knowledge is increasing, the exact pathophysiology remains unclear. TCM represents 1%-2% of all troponin positive acute coronary syndromes, affects predominantly postmenopausal women, and is commonly preceded by exposure to severe physical or emotional stress. Transient wall motion abnormalities mimicking ST-elevation myocardial infarction is expected as well as increase of troponin levels and echocardiography alterations.
