Objectives: To identify the prevalence of extensive ischemia on exercise echocardiography (ExE) relative to workload in patients without known coronary artery disease (CAD), and to investigate whether ExE is useful to assess outcome in those with high exercise capacity (≥10 metabolic equivalents (METs) plus a maximal test (≥85% of their Maximal Age-Predicted Heart Rate (MAPHR). Background: Recent work has suggested low reach of imaging in patients who achieve ≥10 METs and ≥85% of their MAPHR during exercise. Methods: Retrospective analysis on 4,269 patients who underwent ExE, of whom 3,995 achieved ≥85% of their MAPHR. These patients were divided according to the reached workload (
