To maintain consistency, the writing committee worked with members of other committees to harmonize recommendations and eliminate discrepancies. Some recommendations from earlier guidelines have been updated as warranted by new evidence or a better understand- ing of earlier evidence, whereas others that were no longer accurate or relevant or were overlapping were modified; recommendations from previous guidelines that were similar or redundant were eliminated or consolidated when possible. Most of the topics mentioned in the present guideline were addressed in the ACC/AHA 2002 Guideline Update for the Management of Patients With Chronic Stable Angina Summary Article, 7 and many of the recommendations in the present guideline are consistent with those in the 2002 document. Whereas the 2002 update dealt individually with specific drugs and interventions for reducing cardiovascular risk and medical therapy of angina pectoris, the present document recommends a combination of lifestyle modifica- tions and medications that constitute GDMT. In addition, recommendations for risk reduction have been revised to reflect new evidence and are now consistent with the AHA/ ACCF Secondary Prevention and Risk Reduction Therapy for Patients With Coronary and Other Atherosclerotic Vascular Disease: 2011 Update. 8 Also in the present guideline, recommendations and text related to revascularization are the result of extensive collaborative discussions between the PCI and CABG writing committees, as well as key members of the SIHD and UA/NSTEMI writing committees. In a major undertaking, the PCI and CABG guidelines were written concurrently with input from the STEMI guideline writing committee and additional collaboration with the SIHD guide- line writing committee, allowing greater collaboration be- tween these writing committees on revascularization strate- gies in patients with CAD (including unprotected left main PCI, multivessel disease revascularization, and hybrid proce- dures).9,10 Section 5 is included as published in both the PCI and CABG guidelines in its entirety.
