Does the extent of myocardial viability assessed by PET imaging predict improvement in heart failure symptoms after CABG in patients with ischemic cardiomyopathy?
Preoperative assessment of myocardial viability using PET imaging can help identify patients with ischemic cardiomyopathy who will derive the greatest symptomatic benefit from surgical revascularization.
In patients with ischemic cardiomyopathy, the magnitude of improvement in heart failure symptoms after CABG is related to the preoperative extent and magnitude of myocardial viability as assessed by use of PET imaging. Patients with large perfusion-metabolism mismatches exhibit the greatest clinical benefit after CABG.
