C-reactive protein (CRP) was traditionally considered a biomarker of inflammation,however,recent studies have proved that CRP exerts prothrombotic effects on vascular cells and plays a critical role in atherothrombosis.CRP increases the risk of ischemic vascular events,for example,myocardial infarction.CRP has been detected in atherosclerotic lesions in human coronary arteries [1-5].Although CRP has been argued to be involved in the development of atherosclerotic plaque size [6-8],it is surely correlated with activating the blood coagulation system and increasing the risk of thrombosis.The present review focuses on the pivotal role of CRP in trigger of atherosclerosis,stimulation of prothrombetic factor and activation of platelets as well as subsequent development of atherothrombosis.A better understanding of each step involved in this complex process might lead to a new therapeutic strategy to manage patients with CRP-linked atherothrombosis.
