Patients with myocardial infarction require invasive treatment involving coronary angiography to confirm the diagnosis and, in most cases, treatment by angioplasty/stenting. Trans-thoracic ultrasound is central to the initial management of patients admitted to hospital with acute coronary syndrome without ST segment elevation.
The aim of our study is therefore to compare perfusion ultrasound with coronary angiography and MRI in this population in order to determine whether the performance is satisfactory.
Patient over 18 years of age
Hospitalised in cardiology as an emergency for acute coronary syndrome without ST segment elevation with indication for coronary angiography within 72 hours of admission
Not yet undergone coronary angiography.
Troponin >99th percentile, i.e. >27ng/l (troponin I, hypersensitive, Abbott)
Rhythmically unstable patient: sustained ventricular tachycardia, sudden death recovered.
Patient with a known allergy to ultrasound contrast medium
Patient with ST segment elevation.
Patient with a contraindication to MRI.
