Quantitative Relation Between Myocardial Viability and Improvement in Heart Failure Symptoms After Revascularization in Patients With Ischemic Cardiomyopathy

Abstract

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.
