Key result
F-18 FDG PET imaging in patients with tako-tsubo cardiomyopathy demonstrated that the extent of metabolic defect in the apical akinetic area was more severe than the perfusion abnormality.
Observational (n=15)
In tako-tsubo cardiomyopathy, metabolic defects in the apical akinetic area are more severe than perfusion abnormalities, suggesting a catecholamine-induced metabolic disorder.

Stress-induced metabolic defects in Takotsubo warrant mechanistic studies; clinical implications remain uncertain pending larger trials.
Yoshida et al. (2007) conducted an observational in Tako-tsubo cardiomyopathy (n=15). F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET) was evaluated on Metabolic and perfusion abnormalities. F-18 FDG PET imaging in patients with tako-tsubo cardiomyopathy demonstrated that the extent of metabolic defect in the apical akinetic area was more severe than the perfusion abnormality.
