Myocardial scar and insulin resistance predict cardiovascular events in severe ischaemic myocardial dysfunction: a perfusion–metabolism positron emission tomography study

BACKGROUND Clinical outcome can be predicted by metabolism-perfusion positron emission tomography (PET) in patients with severe ischaemic left ventricular dysfunction. This study determined whether the amount of viable or non-viable myocardium detected with a PET scan or clinical-functional parameters might predict cardiovascular events. METHODS All patients had previous myocardial infarction (>6 months previously) and left ventricular ejection fraction (LVEF)
