The rate of physical stress in the systematic review 11 and the rate of secondary TTS in our study were very similar, namely 36% and 37%, respectively. Furthermore, in the systematic review, the rate of cardiogenic shock was 19%, which is quite similar to our study, and the rate of malign arrhythmia was 10%. It is worth emphasizing that the systematic review did not include any studies from South America. Figure 5 – Independent predictors of mortality.
