 Stress echocardiography versus perfusion imaging. Adapted from Marwick18

• Diagnosis of CHDSimilar accuracy in meta-analyses and head-to-head trials
Stress echo less sensitive for mild disease
Perfusion scanning less specific
• Prognostic evaluationSimilar (very good) prognostic implications of a negative test
• Detection of myocardial viabilityStress echo less sensitive but more specific for prediction of long term recovery
