Takotsubo cardiomyopathy: an uncommon cause of reversible heart failure.

Takotsubo cardiomyopathy is increasingly being diagnosed as a cause of acute coronary syndrome in postmenopausal women. It may also present as reversible acute left heart failure with an excellent prognosis for recovery. Although rare, it may be an underdiagnosed condition in the medical intensive care units among patients admitted with non-cardiac acute conditions. Therefore, intensivists must be aware of the possibility of this condition; this can help to avoid unnecessary costly investigations and provide an early, definite prognosis.
