Therefore, the table is meant to offer general guidance and illustration rather than rigid algorithms. CABG indicates coronary artery bypass graft; CAD, coronary artery disease; CCS, Canadian Cardiovascular Society; CK-MB, creatine kinase-MB fraction; ECG, electrocardiogram; MI, myocardial infarction; NTG, nitroglycerin; N/A, not available; TnI, troponin I; TnT, troponin T; and UA/NSTEMI, unstable angina/non ST-elevation myocardial infarction. Modified from Braunwald et al.6 Fihn et al Stable Ischemic Heart Disease: Full Text e361 to have IHD is also beyond the scope of this guideline, but it is addressed in the ACCF/AHA Guideline for Assessment of Cardiovascular Risk in Asymptomatic Adults. 5 Similarly, the present guideline does not apply to patients with chest pain symptoms early after revascularization by either percu- taneous techniques or CABG. Although the division between early and late symptoms is arbitrary, the writing com- mittee believed that this guideline should not be applied to patients who develop recurrent symptoms within 6 months of revascularization. Pediatric patients are beyond the scope of this guideline, because IHD is very unusual in such patients and is related primarily to the presence of coronary artery anomalies. Patients with chest pain syndromes after cardiac transplantation also are not included in this guideline. 1.5. General Approach and Overlap With Other Guidelines or Statements This guideline overlaps with numerous clinical practice guidelines published by the ACCF/AHA Task Force on Practice Guidelines; the National Heart, Lung, and Blood Institute; and the ACP (Table 3). To maintain consistency, the writing committee worked with members of other committees to harmonize recommendations and eliminate discrepancies.
