We thank Dr. Sun and colleagues for their interest in our publication (1) and for their questions that highlight important pathophysiological phenomena that appear unique to Tako-tsubo cardiomyopathy (TTC).

It is true that for the same extent of left ventricular (LV) systolic impairment and indeed for the same degree of elevation of LV end-diastolic pressure (2), patients appear to have lesser degrees of pulmonary edema in acute TTC compared with those experiencing a large acute myocardial infarction (AMI). However, this does not mean that the clinical course in the early stages of acute TTC is “benign.” Conversely, there are significant hemodynamic, arrhythmic, and embolic complications, all of which are life threatening and place the early in-hospital mortality of acute TTC on par with that of AMI
