Pretest Probability
of Ischemia COR LOE Additional Considerations
Prior evidence of
silent ischemia or
high risk for recurrent
cardiac event.
Meets criteria
listed in additional
considerations.
IIa C a) Unable to exercise to adequate
workload or
b) Uninterpretable ECG or
c) History of incomplete coronary
revascularization
Any IIb C a) Prior evidence of silent ischemia
or
b) At high risk for recurrent
cardiac event
No prior evidence
of silent ischemia
and not at high risk
of recurrent cardiac
event.
IIb C For annual surveillance
Any III: No Benefit C a) <5-y intervals aer CABG, or
b) <2-y intervals aer PCI
Î In patients who have no new or worsening symptoms or no prior
evidence of silent ischemia and are not at high risk for a recurrent
cardiac event, the usefulness of annual surveillance exercise ECG
testing is not well established. (IIb-C)
Î Nuclear MPI, echocardiography, or CMR, with either exercise or
pharmacological stress or CCTA, is NOT recommended for follow-up
assessment in patients with SIHD, if performed more frequently than
at: (III-C No Benefit)
• 5-year intervals after CABG or
• 2-year intervals after PCI
