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. |
