Brief summary
This clinical study examines patients presenting with acute myocardial infarction and no significant coronary artery disease on coronary angiography (MINOCA) and patients with MINOCA-mimics with advanced CMR. The present study aims to: * assess the microvascular function with a novel quantitative 3D myocardial perfusion imaging approach in the acute phase and post-convalescence * refine the role and diagnostic potential of advanced quantitative CMR imaging * assess the potential prognostic significance of microvascular dysfunction and epicardial adipose tissue on cardiovascular outcomes Participants will undergo advanced CMR imaging in the acute setting (within 10 days after event) and post convalescence (after 3 months).
Detailed description
Advanced CMR includes a novel free-breathing motion-informed locally low-rank quantitative 3D myocardial perfusion imaging. Perfusion imaging will be compared with 3D late gadolinium enhancement (LGE) imaging. A cine Dixon sequence is performed for the assessment of epicardial adipose tissue (EAT).
Interventions
Advanced CMR imaging including a novel quantitative free-breathing 3D perfusion sequence, 3D LGE imaging and a cine Dixon sequence

Study design
Intervention model description
5 groups of patients (MINOCA, myocarditis, Takotsubo cardiomyopathy, SCAD, NSTEMI) will undergo CMR with 3D perfusion in the acute setting (within 10 days after the event) and post convalescence (after 3 months)
Eligibility
Inclusion criteria
* acute presentation with signs/symptoms of acute coronary syndrome or myocarditis * elevated cardiac biomarkers * no signficant coronary artery disease on coronary angiogram or coronary CT
Exclusion criteria
* pacemaker/other devices or claustrophobia * severe asthma, chronic obstructive lung or kidney disease * acute pulmonary embolism * arrhythmia on ECG * moderate to severe valvular disease
