Table 2 Grading of coronary artery stenosis and management recommendations of symptomatic patients with CAD

From: The validity and applicability of CAD-RADS in the management of patients with coronary artery disease

CAD-RADS categoryStenosis grade (%)Management
0Normal (0)-No further evaluation of ACS is required. Consider other etiologies.
1Minimal (1–24)-Consider evaluation of non-ACS etiology.
-Consider referral for out-patient follow-up for preventive management of coronary atherosclerosis and risk factors modification.
2Mild (25–49)-Consider evaluation of non-ACS etiology.
-Consider referral for out-patient follow-up for preventive management of coronary atherosclerosis and risk factors modification.
3Moderate (50–69)-Consider hospital admission with cardiology consultation, functional testing, and/or ICA for evaluation and management.
-Recommendation for anti-ischemic and preventive management should be considered as well as risk factor modifications. Other treatments should be considered if there is the presence of hemodynamic significant lesion.
4Sever
(A—70–99%)
(B—left main > 50% or 3-vessel obstructive disease)
-Consider hospital admission with cardiology consultation and further evaluation with ICA and revascularization is appropriate.
-Recommendation for anti-ischemic and preventive management should be considered as well as risk factor modifications
5Occluded (100)-Consider expedited ICA on a timely basis and revascularization if appropriate.
-Recommendation for anti-ischemic and preventive management should be considered as well as risk factor modifications.
