Factors favoring PCI over CABG include limited areas of ischemia causing symp- toms, suitable PCI targets, a patent graft to the LAD artery, poor CABG targets, and comorbid conditions. 3.9.6. Unstable Angina/Non ST-Elevation Myocardial Infarction The main difference between management of the patient with SIHD and the patient with UA/NSTEMI is that the impetus for revascularization is stronger in the setting of UA/ NSTEMI, because myocardial ischemia occurring as part of an ACS is potentially life threatening, and associated anginal symptoms are more likely to be reduced with a revascular- ization procedure than with GDMT.494 496 Thus, the indica- tions for revascularization are strengthened by the acuity of presentation, the extent of ischemia, and the ability to achieve full revascularization. The choice of revascularization method is generally dictated by the same considerations used to decide on PCI or CABG for patients with SIHD. 3.9.7.
