Time	Events
Day 1 Emergency department	Patient with history of smoking and very intense stress disorder admitted for retrosternal chest pain radiating to the left arm.
	The electrocardiogram (ECG) indicated sinus tachycardia with no ST-T change (elevated hs-Tn level of 5883.4 ng/L; upper normal limit <15.6).
Cardiac catheterization laboratory	The coronary angiography indicated Type 2A spontaneous coronary artery dissection (SCAD) involving the middle part of the left anterior descending artery, while the left ventriculography showed the typical left ventricular apical ballooning and a hypercontractile base compatible with a Takotsubo syndrome (TTS).
Day 2 Cardiovascular intensive care unit	The cardiac magnetic resonance (CMR) showed transmural myocardial oedema in T2-weighted sequence and the absence of myocardial necrosis in the late gadolinium enhancement images.
	Management included medical therapy with the administration of bisoprolol and aspirin.
Day 4	Hospital discharge.
Three months after discharge	The patient remained asymptomatic and showed no reoccurrence of chest pain.
	The coronary angiography showed normal coronaries. CMR and echocardiography revealed complete resolution.
