['Although numerous studies have demonstrated a positive association of high-sensitivity C-reactive protein (CRP) with the incidence of coronary heart disease (CHD), little information exists regarding this issue in Japanese.', 'The association between CRP and the Framingham Risk Score (FRS) was investigated in 2,523 middle-aged Japanese men without a medical history of CHD. CRP was significantly associated with this score obtained from all FRS factors. After dividing subjects into 4 categories of relative risk estimate for CHD, the geometric mean of CRP (mg/L) increased gradually with the CHD risk (below average: 0.39 [95% confidence interval, 0.37-0.41], average: 0.58 [0.50-0.67], moderately above average: 0.70 [0.57-0.86], high: 0.79 [0.58-1.09], trend p<0.001). However, it should be noted that the mean CRP concentration of the high-risk group was only 0.79 mg/L and a greater proportion (63.8%) of the high-risk subjects was in the low-risk range of CRP (<1 mg/L).'] Is high-sensitivity C-reactive protein quite low in Japanese men at high coronary risk?
