Clinical Trial Summary

The size of the infarct is particularly important prognostic marker. It is clearly established that the extent of the infarct is not only correlated to mortality, but also long-term adverse events. The evaluation of the infarct size at the acute phase of the disease is therefore an essential clinical tool to adapt the immediate treatment and follow-up of patients. It is therefore crucial to have techniques that are effective, precise, reproducible, and easily performed during the acute phase to quantify the size of the infarct following angioplasty. Myocardial scintigraphy and cardiac MRI have been the standard examinations for the evaluation of infarct size. However, these exams are difficult to perform during the acute phase of the infarct owing to difficulties in monitoring unstable patients and the limited availability of the apparatus. It is for this reason that the investigators would like to investigate the rotational angiography (RA), which is comparable to a scanner in its mode of action but does not require transfer of patients as performed using the same apparatus that used for diagnostic coronarography and therapeutic angioplasty. RA is a radiological technique that uses the system employed for coronagraph, and consists rotating the fixed C-Arm around the patient and acquisition of a series of images that are then reconstituted. The investigators propose to evaluate the size of the infarct using RA in comparison with cardiac MRI (standard examination) performed as soon as possible after RA and the investigators hope to demonstrated that RA allows the measurement of an infarct as precisely as cardiac MRI.
