5.1.2. Low-Risk Patients With Stable Chest Pain and No
Known CAD
COR LOE
Recommendations
1 B-NR 1. For patients with stable chest pain and no known CAD
presenting to the outpatient clinic, a model to estimate pretest
probability of obstructive CAD is effective to identify patients
at low risk for obstructive CAD and favorable prognosis in
whom additional diagnostic testing can be deferred.
2a B-R 2. For patients with stable chest pain and no known CAD
categorized as low risk, CAC testing is reasonable as a first-
line test for excluding calcified plaque and identifying patients
with a low likelihood of obstructive CAD.
2a B-NR 3. For patients with stable chest pain and no known CAD
categorized as low risk, exercise testing without imaging
is reasonable as a first-line test for excluding myocardial
ischemia and determining functional capacity in patients with
an interpretable ECG.
