What is the scope of this guideline?
This guideline applies to patients aged 18 years or older with chest pain symptoms suggestive of ischemic heart disease (IHD). 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. Similarly, the present guideline does not apply to patients with chest pain symptoms early after revascularization by either percutaneous techniques or CABG. 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.
