Autonomic neurocardiogenic syndrome is stonewalled by the universal definition of myocardial infarction

Figure 3 Eight clinical conditions causing troponin elevation have triggered different patterns of takotsubo syndrome. Most of the reasons for troponin elevation mentioned in the fourth universal definition of myocardial infarction have been reported to trigger takotsubo syndrome. In this figure, 8 of the mentioned reasons (pheochromocytoma, sepsis, cerebellar bleeding, chronic obstructive pulmonary disease with acute exacerbation, heart block, capecitabine, pancreas operation, and strenuous physical exercise in the form of sexual intercourse) triggering different ballooning’s pattern of takotsubo syndrome are demonstrated.
