Abstract
Objective: To demonstrate, through a narrative-critical review, the main evidences about the pathophysiological conditions of Takotsubo's Cardiomyopathy based on the etiological mechanisms and current theories proposed. Methods: Literature review from the scientific articles PubMed, LILACS and Scielo. Specific descriptors were used to obtain works published between the years 2013 and 2018. The studies were included based on the clinical characteristics and excluded based on the absence of complete publications and on the absence of study in humans. Results: With the adoption of inclusion criteria, 238 articles were identified. Of these, 68 articles were highlighted after using the exclusion criteria. Of the total of articles selected, 27 compose this study, due to the detailed analysis of its contents. The studies analyzed have been conducted in several regions of the world, with emphasis in the United States and Europe. Conclusion: Takotsubo's cardiomyopathy has characteristics already well defined by the scientific literature, which allows to establish its diagnosis. However, there is still a great deal of uncertainty regarding the etiological and definitive therapeutic mechanisms for this diagnostic identity.
