Table 9. Recommendations for Noninvasive Imaging
Recommendations COR LOE
Patients with suspected, acute, or new-onset HF should undergo
a chest x-ray
I C
A 2-dimensional echocardiogram with Doppler should be
obtained for initial evaluation of HF
I C
Repeat measurement of EF is useful in patients with HF who have
had a significant change in clinical status or received treatment
that might affect cardiac function, or for consideration of device
therapy
I C
Noninvasive imaging to detect myocardial ischemia and viability
is reasonable in HF and CAD
IIa C
Viability assessment is reasonable before revascularization in HF
patients with CAD
IIa B
Radionuclide ventriculography or MRI can be useful to assess
LVEF and volume
IIa C
MRI is reasonable when assessing myocardial infiltration or scar IIa B
Routine repeat measurement of LV function assessment should
NOT be performed
III: No
