|Indication||Test||Class||Level of Evidence|
|1. Initial assessment of LV and RV function at rest∗||Rest RNA||I||A|
|2. Assessment of myocardial viability for consideration of revascularization in patients with CAD and LV systolic dysfunction who do not have angina||MPI (see Table 5), PET||I||B|
|3. Assessment of the copresence of CAD in patients without angina||MPI||IIa||B|
|4. Routine serial assessment of LV and RV function at rest||Rest RNA||IIb||B|
|5. Initial or serial assessment of ventricular function with exercise||Exercise RNA||IIb||B|
CAD indicates coronary artery disease; LV, left ventricular; MPI, myocardial perfusion imaging; PET, positron emission tomography; RNA, radionuclide angiography.
↵∗ National consensus treatment guidelines are directed by quantitative assessment of LVEF and identification of LVEF less than or equal to 40%.
