Key Points Question Does myocardial viability testing identify patients with ischemic left ventricular dysfunction who benefit from percutaneous coronary intervention? Findings In this prespecified subgroup analysis of a randomized clinical trial of 610 participants with ischemic left ventricular dysfunction 35% or less, myocardial viability testing with cardiovascular magnetic resonance imaging or stress echocardiography did not identify a population of patients who benefit from percutaneous coronary intervention. The extent of nonviable myocardium was associated with a higher risk of death or hospitalization for heart failure and a lower chance of improvement in left ventricular function. Meaning Findings suggest that the extent of dysfunctional yet viable myocardium was not associated with revascularization outcomes.
