Episode 898: Takotsubo Cardiomyopathy

Contributor: Ricky Dhaliwal, MD

Educational Pearls:

  • Takotsubo cardiomyopathy, also known as "broken heart syndrome," is a temporary heart condition that can mimic the symptoms of a heart attack, including troponin elevations and mimic STEMI on ECG.

  • The exact cause is not fully understood, but it is often triggered by severe emotional or physical stress. The stress can lead to a surge of catecholamines which affects the heart (multivessel spasm/paralysed myocardium).

  • The name "Takotsubo" comes from the Japanese term for a type of octopus trap, as the left ventricle takes on a distinctive shape resembling this trap during systole. The LV is dilated and part of the wall becomes akenetic. These changes can be seen on ultrasound.

  • The population most at risk for Takotsubo are post-menopausal women.

  • Coronary angiography is one of the only ways to differentiate Takotsubo from other acute coronary syndromes.

  • Most people with Takotsubo cardiomyopathy recover fully.
