There is more and more evidence supporting the hypothesis that the mechanism responsible for the transformation of a non-complicated atherosclerotic lesion into an hemorrhagic and ulcerated lesion, with the subsequent acute and unstable clinical status, is due to the onset of an inflammatory reaction. Many studies have tried to investigate the presence of any systemic marker able to predict the prognosis of patients at risk from developing acute events, and to distinguish them from those in stable status. The increase of the levels of C-reactive-protein has been related to the development of acute coronary syndromes, though often the results obtained in the different studies have had a quite poor prognostic value when applied to the general population. The lack of direct association between the increase of the levels of C-reactive-protein and Troponin I seems to rule out the possibility that the inflammatory stimulus might be the consequence of an irreversible injury, even though there is no doubt that severe ischemia is likely to play an active role in this sense. | lld:pubmed |
