Day 0	Epigastric pain after consuming Levosulpiride, followed by haematemesis
Day 0, 1 h	Emergency Department: pH 6.8, PaO2/FiO2 150 mmHg requiring endotracheal intubation; electrocardiogram: sinus tachycardia, ST-segment elevation in anterior and lateral leads; transthoracic echocardiography: akinesia of all middle and apical segments of the left ventricle, left ventricular ejection fraction (LVEF) 20%
Day 0, 2 h	Thoracic and abdominal computed tomography scan showing a mass (5 cm) of the left adrenal gland (suggestive of a pheochromocytoma)
Day 0, 3 h	Coronary angiography: no evidence of relevant coronary artery disease; left ventricular angiography showing apical ballooning with severe reduction in LV function (LVEF 15%)
Day 0, 4 h	Cardiac arrest after Labetalol administration: ventricular fibrillation, CPR, DC-shock 6×, pulseless electrical activity; implantation of Impella CP®, high dose of epinephrine intravenous (i.v.) infusion
Day 1	Tapering and end of epinephrine i.v. infusion
Day 2	Introduction of Doxazosine, Metoprolol, and Amlodipine
Day 3	Introduction of i.v. Urapidil due to resistant hypertension
Day 4	Improved LV function (LVEF 45%), removal of Impella CP®
Day 33	Pheochromocytoma confirmed by significantly increased urinary concentration of metanephrine and normetanephrine

Day 46	Patient’s discharge
