Clinical significance

Procedure

Interpretation

resting image stress image interpretation
normal normal no ischemia
normal wall motion defect stress-induced ischemia
wall motion defect wall motion defect myocardial infarct
normal LV dilation *

* small or no focal ischemia, possible diffuse ischemia, possible multivessel CAD

* dobutamine-induced left ventricular dysfunction & or evidence of ischemia are independent predictors of cardiac mortality

* ECG ST segment & T-wave changes with dobutamine infusion may indicate ischemia

  • they do NOT add to test accuracy (except for risk stratification)
