Assessment of risk of developing myocardial infarction in patients presenting with acute coronary syndromes
Assessment of risk of developing cardiovascular disease or ischemic events in individuals who do not manifest disease at present
C-reactive protein (CRP) is a biomarker of inflammation. Plasma CRP concentrations increase rapidly and dramatically (100-fold or more) in response to tissue injury or inflammation. High-sensitivity CRP (hs-CRP) is more precise than standard CRP when measuring baseline (ie, normal) concentrations and enables a measure of chronic inflammation.
Atherosclerosis is an inflammatory disease and hs-CRP has been endorsed by multiple guidelines as a biomarker of atherosclerotic cardiovascular disease risk.(European 2011, Goff 2013, Jacobson 2014)
A large prospective clinical trial demonstrated significantly less cardiovascular risk for patients with hs-CRP <2.0 mg/L.(1) More aggressive treatment strategies may be warranted in patients with hs-CRP > or =2.0mg/L.
Lower risk: <2.0 mg/L
Higher risk: > or =2.0 mg/L
Acute inflammation: >10.0 mg/L
Values >2.0 mg/L suggest an increased likelihood of developing cardiovascular disease or ischemic events.
This test is recommended for cardiovascular risk assessment only.
C-reactive protein (CRP) is an acute-phase reactant and has high intraindividual variability. Therefore, a single test for high-sensitivity CRP (hs-CRP) may not reflect an individual patient's basal hs-CRP level. Repeat measurement may be required to firmly establish an individual's basal hs-CRP concentration. The lowest of the measurements should be used as the predictive value.
Because CRP is an acute-phase reactant, measurements in apparently healthy individuals may not truly reflect the basal level if inflammation is present.
This hs-CRP assay should be used as a means to assess risk of cardiovascular disease or events. A different CRP test (CRP / C-Reactive Protein [CRP], Serum) should be used to monitor or assess other inflammatory disorders.
Significantly decreased CRP values may be obtained from samples taken from patients who have been treated with carboxypenicillins.(Package Insert: Cardiac C-Reactive Protein (Latex) High Sensitive, Roche Diagnostics. Indianapolis, IN. 08/2013)
