CRP and cardiovascular disorder: Pentameric acute phase reactant protein or CRP is a sensitive risk marker of cardiovascular diseases, as confirmed by recent studies .17, 18 However, the possible role of CRP in atherogenesis as a risk factor or even a useful factor with antiatherogenic properties is still questionable which can be seen in the occasionally contradictory results of previous studies .9–12, 19 The present study shows that CRP is able to inhibit the invitro oxidation of LDL in a direct relationship with concentration, Nonetheless the biochemical mechanism whereby this protein shows this ability is not clear.
