The Living Guidelines: UA/NSTEMI Recomendations for CABG Suggest Revisions to the CLASS IIb Guidelines

Click on the edit button above to make suggested revisions to the guidelines.

Coronary artery bypass graft surgery may be considered in patients with UA/NSTEMI who have 1- or 2-vessel disease not involving the proximal LAD with a modest area of ischemic myocardium when percutaneous revascularization is not optimal or possible. (If there is a large area of viable myocardium and high-risk criteria on noninvasive testing, this recommendation becomes a Class I recommendation.) (Level of Evidence: B)
 * Class IIb
