Summary

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.

Conditions

  • Myocardial Infarction (MI)

Interventions

OTHER

perfusion ultrasound

During the examination, the power of the probe will be increased in order to assess myocardial perfusion. The contrast agent bubbles are destroyed by applying a 'flash', i.e. a temporary increase in the power of the ultrasound beam. Systole after systole, on a recorded loop, the filling velocity of the myocardium, which depends on myocardial blood flow, is analysed. The assessment of perfusion is visual and qualitative.
