PURPOSE OF REVIEW: Low-grade inflammation is characteristic of the metabolic syndrome (MetS). C-reactive protein (CRP), the best characterized biomarker of inflammation, is also an independent predictor of future cardiovascular events. The purpose of this review is to outline the role of inflammation and high sensitivity CRP in the MetS.

RECENT FINDINGS: Emerging laboratory and epidemiological data now link inflammation and high sensitivity CRP to insulin resistance and adiposity and other features of MetS. Furthermore, in large prospective studies, increased high sensitivity CRP levels in MetS confer greater cardiovascular risk. CRP has been shown to impair insulin signaling and contributes to atherothrombosis.

SUMMARY: Thus, although a high CRP level predisposes to increased cardiovascular risk in MetS, future investigation is warranted on the in-vivo role of CRP in mediating vascular effects and resulting in increased cardiovascular events in MetS patients.
