It is a spontaneous, observational cross-sectional and single-center imaging (CT and MRI) study, coupled with clinical-laboratory data. Patients with acute chest pain with low/intermediate probability of coronary artery disease, ECG and/or troponin not diagnostic or altered according to the current "standards of care" used in the ED/Department (ESC Guidelines 2020), will be enrolled consecutively and will undergo CT examinations by means of "Spectral" CT technology. CT investigation will allow to identify any non-myocarditis causes of acute chest pain and by means of spectral analysis of CT images it will try to identify signs suggestive of damage myocardial (such as ECV, LIE, hyperemia and edema).
Age greater than or equal to 18 years;
patients with acute chest pain and indication for triple-rule-out CT or coronary CT examination, i.e. low/intermediate probability of acute coronary artery disease, ECG and/or troponin not diagnostic or altered;
Obtaining informed consent
Absolute contraindications to CT examination and/or iodinated mdc administration (i.e. pregnancy, severe renal impairment in non-dialysis patients with GFR < 15-30 ml/min/1.73m2 );
CT examinations that do not allow diagnostic information to be provided because they are assessed as quality too scarce and not interpretable (affected by artifacts such as motion artifacts)
