"In Takotsubo cardiomyopathy it sounds like the person's body literally gives them a heart attack."
Not a heart attack. The article clearly says, "Takotsubo cardiomyopathy is a rare, temporary ailment that has similar symptoms to a heart attack. Unlike a heart attack, however, takotsubo cardiomyopathy does not involve restricted blood flow."
This is a temporary condition, generally with no permanent damage.
