Abstract
This viewpoint pertains to the still elusive pathophysiology of the Takotsubo syndrome (TTS), maintaining the position that this affliction is not the result of coronary vasospasm (CV) involving one or more coronary arteries. Although CV has been rarely encountered in the acute stage of TTS, or elicited via provocative testing in the subacute stage of the disease, it does not appear to be the cause of TTS as shown by the bulk of the published relevant literature. The author provides some speculations to explain the spontaneous appearance of CV, or its artificial elicitation, in some patients with TTS. However while we are striving to unravel the pathophysiology of TTS, we should keep an open mind about a possible role for CV in the causation of TTS.
