Contribution of Myocardial Perfusion Imaging in the Initial Assessment of Acute Coronary Syndromes Without ST Elevation for the Diagnosis of Myocardial Infarction or Differential Diagnoses
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.
