CABG indicates coronary artery bypass graft; CAD, coronary artery disease; COPD, chronic obstructive pulmonary disease; COR, class of recommendation; EF, ejection fraction; LAD, left anterior descending; LIMA, left internal mammary artery; LOE, level of evidence; LV, left ventricular; N/A, not applicable; PCI, percutaneous coronary intervention; SIHD, stable ischemic heart disease; STEMI, ST-elevation myocardial infarction; STS, Society of Thoracic Surgeons; SYNTAX, Synergy between Percutaneous Coronary Intervention with TAXUS and Cardiac Surgery; TIMI, Thrombolysis in Myocardial Infarction; UA/NSTEMI, unstable angina/non ST-elevation myocardial infarction; UPLM, unprotected left main disease; and VT, ventricular tachycardia. Hillis et al 2011 ACCF/AHA CABG Guideline e669 anatomy for PCI and who are good candidates for CABG.301,305,307,312 320 (Level of Evidence: B) Non Left Main CAD Revascularization Class I 1. CABG to improve survival is beneficial in patients with significant (>70% diameter) stenoses in 3 major coronary arteries (with or without involve- ment of the proximal LAD artery) or in the proximal LAD plus 1 other major coronary artery.314,318,341 344 (Level of Evidence: B) 2. CABG or PCI to improve survival is beneficial in survivors of sudden cardiac death with presumed ischemia-mediated ventricular tachycardia caused by significant (>70% diameter) stenosis in a major coronary artery. (CABG Level of Evidence: B271,345,347; PCI Level of Evidence: C345) Class IIa 1. CABG to improve survival is reasonable in patients with significant (>70% diameter) stenoses in 2 major coronary arteries with severe or extensive myocardial ischemia (eg, high-risk criteria on stress testing, abnormal intracoronary hemodynamic eval- uation, or >20% perfusion defect by myocardial perfusion stress imaging) or target vessels supplying a large area of viable myocardium.348 351 (Level of Evidence: B) 2.
