Definitely indicated:
(1) Noninvasive testing shows high risk findings.
(2) Equivocal or nondiagnostic findings on noninvasive testing in a high risk patient undergoing a high-risk surgical procedure.
(3) Unstable angina.
(4) Angina unresponsive to adequate medical therapy.
May be indicated depending on circumstances:
(1) Noninvasive testing shows intermediate risk findings.
(2) Equivocal or nondiagnostic findings on noninvasive testing in a low or moderate risk patient undergoing a high-risk surgical procedure.
(3) Urgent noncardiac surgery in a patient recovering from an acute myocardial infarction.
(4) Perioperative myocardial infarction.
Not indicated - unable to perform a revascularization procedure:
(1) The patient refuses any coronary revascularization procedure.
(2) Severe left ventricular dysfunction in a patient not a surgical candidate for a revascularization procedure.
(3) The patient is not a candidate for a revascularization procedure because of concommitant medical disorders.
Not indicated - practical reasons:
(1) To screen a patient for coronary artery disease without having done appropriate noninvasive testing.
(2) Normal technically adequate coronary angiogram within the past 5 years.
(3) Asymptomatic after coronary revascularization AND good exercise capacity
(4) Low risk findings on noninvasive testing AND low risk noncardiac surgery.
(5) Low risk findings on noninvasive testing AND mild stable angina AND good left ventricular function.
