CDC/AHA Scientific Statement on Inflammatory Markers and Cardiovascular Disease: Recommendations for Population Science • Class III (evidence/agreement that the procedure is not useful/effective and may be harmful), Evidence level C (consensus opinion of experts) • The entire adult population should not be screened for hs-CRP for purposes of cardiovascular risk assessment Pearson TA et al. Circulation 2003;107:499–511.
CDC/AHA Scientific Statement on Inflammatory Markers and Cardiovascular Disease: Recommendations for Laboratory Testing • Class IIa (in favor of usefulness), Evidence level B (data derived from nonrandomized studies) • 2 measurements, optimally 2 weeks apart, should be averaged, in fasting or nonfasting metabolically stable patients. If hs-CRP >10 mg/L, test should be repeated and patient examined for sources of infection or inflammation • hs-CRP risk categories: • Low: <1 mg/L • Average: 1–3 mg/L • High: >3 mg/L Pearson TA et al. Circulation 2003;107:499–511.
CDC/AHA Scientific Statement on Inflammatory Markers and Cardiovascular Disease: Recommendations for Clinical Practice (I) • Class IIa (in favor of usefulness), Evidence level B (data derived from nonrandomized studies) • In patients at intermediate global risk (10–20%/10 yr), hs-CRP measurement may help direct evaluation and therapy for primary prevention; benefits uncertain. • Patients with persistent unexplained hs-CRP elevation >10 mg/L should be evaluated for noncardiovascular etiologies. • In patients with stable coronary disease or ACS, hs-CRP may be useful as a marker of prognosis for recurrent events; benefits uncertain. Pearson TA et al. Circulation 2003;107:499–511.
CDC/AHA Scientific Statement on Inflammatory Markers and Cardiovascular Disease: Recommendations for Clinical Practice (II) • Class IIb (usefulness less well established), Evidence level B (data derived from nonrandomized studies) • hs-CRP measurement may be used as part of global risk assessment in primary prevention; benefits uncertain. • hs-CRP may improve motivation for lifestyle modification; benefits uncertain. Pearson TA et al. Circulation 2003;107:499–511.
