Patients presenting with STEMI and late revascularization can suffer from severe left ventricular dysfunction. Midterm and longterm mortality can be determined by the risk of fatal ventricular arrythmias. For this specific population, ESC guidelines currently recommend a waiting period of up to 40 days after a STEMI with severe left ventricular dysfunction before considering ICD implantation for primary prevention of sudden death.This delay is allocated to judge left ventricular recovery.
This study aims to see whether early cardiac MRI with specific sequences can help predict which patients will most probably not recover their left ventricular function and benefit from earlier ICD implantation.

The purpose of this study is to determine the role of inflammation in the high prevalence of psychiatric disorders in skin-restricted lupus (SRL) patients. SRL is an inflammatory disease. Inflammation can lead to a decrease in the synthesis of neurotransmitters via the activation of the IDO enzyme and to induce the synthesis of neurotoxic molecules (kynurenin pathway). This leads to the development of psychiatric disorders.
Investigator therefore want to compare inflammation and neurotransmitter synthesis in SRL patients according to the presence or absence of psychiatric disorders.
Investigator expect a decrease in neurotransmitter synthesis and activation of the kynurenin pathway in patients with a psychiatric disorder.

Left ventricular remodeling is a common complication in patients with ST-elevation myocardial infarction (STEMI ) and may lead to heart failure. Hemodynamic, metabolic and inflammatory mechanisms are involved in this pathophysiological process. Recent data demonstrated that remote, noninfarct-related region of the myocardium is also implicated. There is no data about the assessment of coronary endothelial function or myocardial fibrosis in the remote zone in patients with STEMI . The correlation between these parameters and left ventricular remodeling is not known.
