Original Article Almeida Junior et al. Takotsubo Multicenter Registry (REMUTA) Arq Bras Cardiol. 2020; 115(2):207-216 Limitations This registry is a retrospective analysis of medical records. For this reason, some data were missing, especially those from complementary exams, whether due to their absence from medical records or, more likely, because they were not performed. Only 20 patients (11.8%) underwent magnetic resonance (MR), but this is a common characteristic in this type of study, and it reflects clinical practice. In the Japanese registry, only 5.5% of patients underwent MR. Although mortality data during long-term follow-up tend to be quite reliable, we do not have data on post-discharge clinical follow-up. Conclusion REMUTA is the first multicenter Brazilian registry of TTS. Its results show that TTS is not a benign pathology, as was once thought, especially in the secondary TTS subgroup which has an elevated rate of complications and mortality. Specific strategies for dealing with this subgroup should be developed with the aim of improving care quality and clinical outcomes for these patients.
