ACCEPTED MANUSCRIPT ECG changes and prognosis of Takotsubo cardiomyopathy
We read the article “Stimulant-related Takotsubo cardiomyopathy” by Butterfield et al.  in the previous issue of the American Journal of Emergency medicine with great interest. The authors described a very interesting case of Takotsubo cardiomyopathy (TC) associated with cocaine abuse. The patient did have a remarkable electrocardiogram (ECG) changes and was successfully treated with conservative management. We would like to emphasize two important issues related to this case presentation. First, although the majority of patients with TC have ECG changes at presentation, as seen in the this case, up to 30% of patients could have a completely normal ECG [2, 3]. Thus, a normal ECG does not always rule out the diagnosis of TC. Second, TC is not always a benign condition and sometimes an aggressive intervention is required as a recent systematic review had demonstrated an in-hospital mortality of up to 3% .
