ACC/AHA recommendations for PCI in patients with chronic stable angina⁴

Recommendations	Class I LOE
2-vessel or 3-vessel disease with significant proximal LAD lesions, with anatomy enabling catheter-based therapy and normal LVF; diabetics under treatment excluded.	I (B)
1-vessel or 2-vessel disease without significant proximal LAD lesions, with high risk on noninvasive testing and a large area of viable myocardium.	I (B)
Prior PCI with either recurrence of stenosis or high risk on noninvasive testing.	I (C)
Failure of optimum medical therapy and with acceptable risk for revascularization procedure.	I (B)
