N: 1. Takotsubo cardiomyopathy was first reported in Japan in 1990. The word ’Takotsubo’ means ‘octopus pot’ in Japanese, as the left ventricle of the heart changes into a similar shape as the pot – developing a narrow neck and a round bottom.
2. A temporary condition where your heart muscle becomes suddenly weakened or ‘stunned’.
The left ventricle, one of the heart’s chambers, changes shape and enlarges. This means this part of the heart doesn’t pump well.
3. The modified Mayo Clinic criteria for diagnosis of TCM can be applied to a patient at the time of presentation. The diagnosis requires the presence of all four of the following (see Workup):
Transient hypokinesis, dyskinesis, or akinesis of the LV midsegments, with or without apical involvement; the regional wall-motion abnormalities extend beyond a single epicardial vascular distribution, and a stressful trigger is often, but not always, present

  • Absence of obstructive coronary disease or angiographic evidence of acute plaque rupture
  • New ECG abnormalities (either ST-segment elevation and/or T-wave inversion) or modest elevation in the cardiac troponin level
  • Absence of pheochromocytoma or myocarditis.
