Recommendations for Use of Radionuclide Testing in Diagnosis, Risk Assessment, Prognosis, and Assessment of Therapy After Acute STEMI

Patient Subgroup(s)IndicationTestClassLevel of Evidence
All1. Rest LV functionRest RNA or ECG-gated SPECTIB
Thrombolytic therapy without catheterization2. Detection of inducible ischemia and myocardium at riskStress MPI with ECG-gated SPECT whenever possibleIB
Acute STEMI3. Assessment of infarct size and residual viable myocardiumMPI at rest or with stress using gated SPECTIB
4. Assessment of RV function with suspected RV infarctionEquilibrium or FPRNAIIaB

ECG indicates electrocardiography; FPRNA, first-pass radionuclide angiography; LV, left ventricular; MPI, myocardial perfusion imaging; RNA, radionuclide angiography; RV, right ventricular; SPECT, single-photon emission computed tomography; STEMI, ST-segment elevation myocardial infarction.
