Implication
Viability by PET may predict CABG symptom benefit in ischemic cardiomyopathy; extends observational data but leaves open randomized confirmation.
Structured PICO
Does the extent of myocardial viability assessed by PET imaging predict improvement in heart failure symptoms after CABG in patients with ischemic cardiomyopathy?
P
Population
Patients with ischemic cardiomyopathy
I
Intervention
CABG (revascularization) with preoperative assessment of myocardial viability using PET imaging
O
Outcome
Improvement in heart failure symptomspatient reported
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.
