May inform viability testing in ischemic cardiomyopathy; leaves open whether PET-guided revascularization improves outcomes.
What is the prevalence of myocardial viability as detected by PET in patients with ischemic cardiomyopathy?
More than half of patients with ischemic cardiomyopathy have viable myocardium on PET imaging, suggesting a substantial proportion may benefit from revascularization.
Auerbach et al. (1999) studied this question.
