Overview
Overview
C-reactive protein (CRP) is an established marker of inflammation and has recently been suggested to be an important contributor to the pro-inflammatory and prothrombotic elements of cardiovascular disease (CVD) risk. Extremely high CRP levels are seen in acute inflammatory states, but the small elevations that are indicative of the pro-inflammatory and pro-thrombotic states implicated in the metabolic syndrome require high sensitivity assays, and are thus referred to as hs-CRP levels.
Studies have shown correlations between elevated hs-CRP and increased risk of future heart attacks, ischemic stroke, and peripheral arterial disease. Overweight, obese, insulin resistant, and diabetic individuals typically have elevated hs-CRP levels; elevations in hs-CRP levels have also been found to predict the development of diabetes.
