Quantitative myocardial perfusion indices predict outcomes in native vessel disease, but their prognostic performance in patients with prior CABG is unknown.<h4>Objectives</h4>In this study, we sought to evaluate whether global stress myocardial blood flow (MBF) and perfusion reserve (MPR) derived from perfusion mapping cardiac magnetic resonance (CMR) independently predict adverse outcomes in patients with prior CABG.<h4>Methods</h4>This was a retrospective analysis of consecutive patients with prior CABG referred for adenosine stress perfusion CMR.
