Class IIa Guidelines
1. Percutaneous coronary intervention is reasonable for focal saphenous vein graft lesions or multiple stenoses in UA/NSTEMI patients who are undergoing medical therapy and who are poor candidates for reoperative surgery. (Class IIa Level of Evidence: C)

 AHA / ACC 2007 PCI Guidelines Class IIa Recommendation 1 for Initial Conservative versus Initial Invasive Strategies in patients with Unstable Angina / Non ST Elevation MI should be CLASS I CLASS IIa CLASS IIb CLASS III 2. Percutaneous coronary intervention (or CABG) is reasonable for UA/NSTEMI patients with one or two vessel CAD with or without significant proximal left anterior descending CAD but with a moderate area of viable myocardium and ischemia on noninvasive testing. (Class IIa Level of Evidence: B)

 AHA / ACC 2007 PCI Guidelines Class IIa Recommendation 2 for Initial Conservative versus Initial Invasive Strategies in patients with Unstable Angina / Non ST Elevation MI should be CLASS I CLASS IIa CLASS IIb CLASS III 3. Percutaneous coronary intervention (or CABG) can be beneficial compared with medical therapy for UA/NSTEMI patients with 1-vessel disease with significant proximal left anterior descending CAD. (Class IIa Level of Evidence: B)

 AHA / ACC 2007 PCI Guidelines Class IIa Recommendation 3 for Initial Conservative versus Initial Invasive Strategies in patients with Unstable Angina / Non ST Elevation MI should be CLASS I CLASS IIa CLASS IIb CLASS III 4. Use of PCI is reasonable in patients with UA/NSTEMI with significant left main CAD (greater than 50% diameter stenosis) who are candidates for revascularization but are not eligible for CABG or who require emergency intervention at angiography for hemodynamic instability. (Class IIa Level of Evidence: B)

 AHA / ACC 2007 PCI Guidelines Class IIa Recommendation 4 for Initial Conservative versus Initial Invasive Strategies in patients with Unstable Angina / Non ST Elevation MI should be CLASS I CLASS IIa CLASS IIb CLASS III
