Can takotsubo cardiomyopathy be familial?

Takotsubo cardiomyopathy is a form of reversible left ventricular dysfunction that is presumably precipitated by stress. Our observations of the recurrence of takotsubo cardiomyopathy in an individual and the occurrence of a reversible cardiomyopathy in her daughter lead us to speculate on the possibility of a familial predisposition to this entity or its variants.
