C-reactive protein and primary prevention of ischemic heart disease

C-reactive protein (CRP) is the prototype acute phase reactant and therefore a marker of systemic inflammation. In the last decades, accumulating data have demonstrated the role of inflammation in the pathogenesis of ischemic heart disease. High CRP levels, measured by high-sensitivity methods, on admission have a short-term negative prognostic value and are associated with a worse outcome. In epidemiological studies, minor elevations of CRP are associated with future risk of myocardial infarction, stroke and peripheral vascular disease. This increased risk is independent of other biochemical and clinical risk factors, and the association between high CRP and an abnormal cholesterol ratio significantly increases the risk in the individual patient. Finally, the observation of an increased level of CRP may be of clinical utility in primary prevention, because these subjects favourably benefit from statin therapy.
