4 Classification of Recommendations and Levels of Evidence *Data available from clinical trials or registries about the usefulness/efficacy in different subpopulations, such as gender, age, history of diabetes, history of prior myocardial infarction, history of heart failure, and prior aspirin use. A recommendation with Level of Evidence B or C does not imply that the recommendation is weak. Many important clinical questions addressed in the guidelines do not lend themselves to clinical trials. Even though randomized trials are not available, there may be a very clear clinical consensus that a particular test or therapy is useful or effective.†For comparative effectiveness recommendations (Class I and IIa; Level of Evidence A and B only), studies that support the use of comparator verbs should involve direct comparisons of the treatments or strategies being evaluated.

10 General Approaches to Risk Stratification Recommended Approaches to Risk StratificationGeneral Approaches to Risk Stratification
11 Recommendations for General Approaches to Risk Stratification Global risk scores (such as the Framingham Risk Score [FRS]) that use multiple traditional cardiovascular risk factors should be obtained for risk assessment in all asymptomatic adults without a clinical history of CHD. These scores are useful for combining individual risk factor measurements into a single quantitative estimate of risk that can be used to target preventive interventions.BIIIaIIbIII

15 Lipoprotein and Apolipoprotein Assessments Recommended Approaches to Risk StratificationLipoprotein and Apolipoprotein Assessments
16 Recommendation for Lipoprotein and Apolipoprotein Assessments Measurement of lipid parameters, including lipoproteins, apolipoproteins, particle size, and density, beyond a standard fasting lipid profile is not recommended for cardiovascular risk assessment in asymptomatic adults.IIIaIIbIII
17 Other Circulating Blood Markers and Associated Conditions Recommended Approaches to Risk StratificationOther Circulating Blood Markers and Associated Conditions
18 Recommendation for Natriuretic Peptides BIIIaIIbIIIMeasurement of natriuretic peptides is not recommended for CHD risk assessment in asymptomatic adults.
19 Recommendations for Measurement of C-Reactive Protein (CRP) BIIIaIIbIIIIn men 50 years of age or older or women 60 years of age or older with LDL cholesterol less than 130 mg/dL; not on lipid-lowering, hormone replacement, or immunosuppressant therapy; without clinical CHD, diabetes, chronic kidney disease, severe inflammatory conditions, or contraindications to statins, measurement of CRP can be useful in the selection of patients for statin therapy.
20 Recommendations for Measurement of C-Reactive Protein (continued) BIIIaIIbIIIIn asymptomatic intermediate-risk men 50 years of age or younger or women 60 years of age or younger, measurement of CRP may be reasonable for cardiovascular risk assessment.In asymptomatic high-risk adults, measurement of CRP is not recommended for cardiovascular risk assessment.In low-risk men younger than 50 years of age or women 60 years of age or younger, measurement of CRP is not recommended for cardiovascular risk assessment.BIIIaIIbIIIBIIIaIIbIII
21 Recommendation for Measurement of Hemoglobin A1C IIaIIbIIIMeasurement of hemoglobin A1C (HbA1C) may be reasonable for cardiovascular risk assessment in asymptomatic adults without a diagnosis of diabetes.
22 Recommendations on testing for Microalbuminuria (Urinary Albumin Excretion) In asymptomatic adults with hypertension or diabetes, urinalysis to detect microalbuminuria is reasonable for cardiovascular risk assessment.In asymptomatic adults at intermediate risk without hypertension or diabetes, urinalysis to detect microalbuminuria might be reasonable for cardiovascular risk assessment.BIIIaIIbIIIBIIIaIIbIII

32 Recommendation for Stress Echocardiography Stress echocardiography is not indicated for cardiovascular risk assessment in low- or intermediate-risk asymptomatic adults.

33 Recommendations for Myocardial Perfusion Imaging Stress MPI may be considered for advanced cardiovascular risk assessment in asymptomatic adults with diabetes or asymptomatic adults with a strong family history of CHD or when previous risk assessment testing suggests high risk of CHD, such as a coronary artery calcium (CAC) score of 400 or greater.Stress MPI is not indicated for cardiovascular risk assessment in low- or intermediate-risk asymptomatic adults. (Exercise or pharmacologic stress MPI is a technology primarily used and studied for its role in advanced cardiac evaluation of symptoms suspected of representing CHD and/or estimation of prognosis in patients with known coronary artery disease.)IIIaIIbIIIIIIaIIbIII
34 Recommendations for Calcium Scoring Methods Measurement of CAC is reasonable for cardiovascular risk assessment in asymptomatic adults at intermediate risk (10% to 20% 10-year risk.Measurement of CAC may be reasonable for cardiovascular risk assessment persons at low to intermediate risk (6% to 10% 10-year risk).Persons at low risk (<6% 10-year risk) should not undergo CAC measurement for cardiovascular risk assessment.BIIIaIIbIIIBIIIaIIbIIIBIIIaIIbIII
