The diagnosis was mainly made by addressing one of the four criteria of Mayo Clinic for the diagnosis of TS: 1) mid and apical dyskinesia of the left ventricular segments with regional wall motion abnormalities; 2) absence of obstructive coronary artery disease; 3) appearance of new ECG abnormalities (T-wave inversion); and 4) absence of pheochromocytoma or myocarditis.10 Additionally, elevated troponin and proBNP levels were found in this case, which is frequent in patients with TS reported in international registries.5 Therefore, it is also considered a diagnostic criterion. This evidence concerns the gene NPPB and pheochromocytoma.
