C-reactive protein and atherothrombosis.

Circulating concentrations of C-reactive protein (CRP), the classical acute phase protein and sensitive systemic marker of inflammation, significantly predict atherothrombotic events and outcome after acute myocardial infarction, demonstrating the key role of inflammation in atherosclerosis and its complications. The binding specificity of CRP for low density lipoproteins, for modified low density lipoproteins, and for damaged and dead cells, coupled with the capacity of bound CRP to activate complement, and with the presence of CRP in atheroma and acute myocardial infarction lesions, all suggest a possible pathogenetic role of CRP. Development of drugs to block binding of CRP to its various ligands in vivo will enable this hypothesis to be tested.
