Podcast 768: Takotsubo Cardiomyopathy

Contributor: Peter Bakes, MD

Educational Pearls:

• 3% of cases of acute coronary syndrome are due to Takotsubo
• Takotsubo  cardiomyopathy or "broken heart syndrome" can occur with severe physiologic or emotional stressors, as these events can result in a profound outpouring of sympathetic neurotransmitters (epinephrine/norepinephrine)
• Receptors for these catecholamines are very dense around the apex of the heart, so the apical aspect of the heart can balloon outward as a result of this surge
• Most often cases resolve in several weeks although in rare cases it can lead to congestive heart failure or a thrombus formation
