The takotsubo happen to have the same, or a similar shape as the human heart during a contraction. And the "broken heart syndrome" was first described in Japan and that is why it was given the name, "Takotsubo."
I was diagnosed with Takotsubo in March of 2013. But that's not what the paperwork called it. Instead, I was diagnosed with a myocardial infarction, caused by apical ballooning syndrome. Apical ballooning syndrome is also known as Takotsubo, which is also known as "Broken Heart Syndrome." And yes, you can die of a broken heart.
