Prediction of Recurrent Events With 18F-Fluoride (PREFFIR)

This is a multi-centre observational study. It will make use of the positron emission tomography (PET) tracer 18F-sodium fluoride (18F-NaF) as a marker of coronary plaque vulnerability to detect culprit and non-culprit unstable coronary plaques in patients with recent myocardial infarctions. The investigators will then perform long-term follow-up of these patients to determine the prognostic significance of coronary 18F-NaF uptake.
