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

CAD-RADS category

Stenosis grade (%)

Management

0

Normal (0)

-No further evaluation of ACS is required. Consider other etiologies.

1

Minimal (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.

2

Mild (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.

3

Moderate (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.

4

Sever

(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

5

Occluded (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.
