Also called acute stress-induced cardiomyopathy (heart disease) or broken heart syndrome, takotsubo is triggered by intense emotional or physical stress. The heart fails. The patient may die.
►►► WHY read this? Takotsubo is not well known but reasonably frequent. It shows how significant can be the influence of stress on heart disease. ◄◄◄
No, it’s not about my broken heart.
Who, when, what (scientific background)
First described in 1990, takotsubo has gained substantial attention during the past 15 years, although still being underdiagnosed. [Napp et al., 2020] There is a clear gender predilection towards women (9:1). It occurs predominantly post-menopausal (but is seen increasingly at a younger age) and is commonly associated with stress. It’s often triggered by a major stressful event inducing anxiety, fear, depression, or grief. From the beginning, it has been associated with the absence of coexisting major heart vessel disease.
Probably 7% of patients with presumed heart attacks are suffering from broken heart syndrome. [Dawson, 2018] It mimics an acute heart attack with a sudden onset of chest pain and breathlessness. It also has a prognosis comparable to myocardial infarction. [see also: “How to Prevent Your Next Heart Attack“]
The heart gets the shape of a takotsubo (Japanese octopus-fishing pot) with a typical ballooning at the heart tip (apex) on imaging during systole (heart contraction phase) and dysfunction of the left heart chamber. There is no obstruction visible of any coronaries (arteries of the heart).
Physically, the mechanism involves acute inflammation of the heart muscle, probably on top of a low-grade chronic inflammatory state. [Scally et al., 2019] Also, spasms of small blood vessels around the heart may be involved. [Napp et al., 2020]
It is reversible in the majority of cases within a month, but complications are possible during the acute phase, including death. Also, there may be long-term damage to the heart muscle and heart failure.
From stress to inflammation
“The causative association with a type of emotion or stress has been widely accepted as the hallmark of this condition (mostly as a negative experience but in a minority a positive one,[Ghadri et al., 2016]… Many triggers have been described, for example, bereavement, near-miss road traffic accident, arguments, conflict, divorce, public speaking, a severe fright, protracted stress and hardship or any physical illness such as cancer, administration of chemotherapy, infections, diarrhea/vomiting, routine general anesthesia, cardioversions and many others.” [Dawson, 2018]
Around half of takotsubo patients suffer from an acute or chronic neurological or psychiatric disease [Templin et al., 2015], suggesting that the brain is a critical causal component. Also, preexisting type D personality in takotsubo patients provides susceptibility, suggesting that coping mechanisms and an individually increased response to stress drive the onset [Compare et al., 2013].
That makes takotsubo a disease (one of many, including COVID) in which acute mental stress and immuno-inflammatory reactions go together. Acute-on-chronic stress is probably an important predisposing factor. Until now, little research has been done on the acute-on-chronic stress condition. Contrary to this, we know quite a lot about the influence of chronic stress on the immune system. Sadly, little of this has been translated into medical practice or general healthcare. “Just relax a bit” is not enough.
Takotsubo deaths are one sorry consequence of this neglect.
In cardiology, the emotional triggering of cardiac events has been described for several conditions and pathways: immunological, hormonal, neurological. Knowledge about this comes from a plethora of epidemiological and clinical data; in one word: science.

What shall we do?
You could have guessed if you know a bit of AURELIS. I’m right on track of creating an app with mental exercises that may be very useful in all this.
If you are interested, please let me know. According to the interest, it may get realized sooner. It would be nice to see the app scientifically validated. If it works, it works. If not, so be it. In the latter case, I would be amazed.
