[The significance of high sensitive C reactive protein as a risk factor for cardiovascular diseases].
Chronic inflammation is involved in the pathogenesis of cardiovascular diseases (CVD). Several prospective studies have indicated that an elevated high sensitive C-reactive protein (hs-CRP) level is a risk factor for CVD. These results were also confirmed by prospective studies in Japan both for primary and secondary prevention. A randomized control study using statins also revealed that lower levels of both LDL cholesterol and hs-CRP were independently related to the incidence of CVD. Recent meta-analysis revealed that hs-CRP was a risk factor not only for CVD but for other diseases including cancers. It revealed that the absolute value of hs-CRP varied among the study populations. The mechanism of how hs-CRP is associated with the pathogenesis of CVD is not fully understood. Generally, inflammation in the vascular wall and the release of inflammatory cytokines from macrophages was considered to the main mechanism, but infection with such as chlamydia or Helicobacter pylori, and periodontal disease have been postulated as the causes of systemic inflammation. Recently, visceral fat accumulation and its cross-interaction with inflammatory cells have been proposed as the cause of systemic inflammation as "innate inflammation". Our original cross sectional studies also showed the correlations of hs-CRP with BMI and triglyceride. Although there is no specific therapy for the reduction of hs-CRP, we have to consider hs-CRP as a risk factor for CVD which complements other classical risk factors.
