ABSTRACT
<p><b>BACKGROUND</b>Arterial stiffness increases with age and is also associated with traditional cardiovascular risk factors. Little is known about the relations of homocysteine and high-sensitivity C-reactive protein (hs-CRP) to arterial stiffness in the Chinese community. The aim of the present study was to investigate the association of plasma homocysteine and hs-CRP levels with arterial stiffness in a community-based cohort.</p><p><b>METHODS</b>We related levels of homocysteine and hs-CRP to four measures of arterial stiffness (carotid-femoral pulse wave velocity (PWV), carotid-radial PWV, carotid-ankle PWV and heart rate corrected augmentation index) in 1680 participants from two communities of Beijing, China. Arterial stiffness was measured within two days of the time of biomarker measurement.</p><p><b>RESULTS</b>In univariate analysis, homocysteine was positively associated with the carotid-femoral PWV (r = 0.211, P < 0.0001), carotid-radial PWV (r = 0.120, P < 0.0001) and carotid-ankle PWV (r = 0.148, P < 0.0001), whereas it was inversely related to the augmentation index (r = -0.052, P = 0.016). Hs-CRP was positively associated with the carotid-femoral PWV (r = 0.074, P = 0.001) and carotid-ankle PWV (r = 0.050, P = 0.02). In multiple-adjusted models (R(2) = 0.57), homocysteine levels remained a significant determinant of the carotid-femoral PWV (standardized β = 0.065, P = 0.007), whereas the association of hs-CRP with measurements of arterial stiffness was not present.</p><p><b>CONCLUSIONS</b>In the Chinese population, plasma homocysteine levels are associated with alterations of aortic stiffness, whereas plasma levels of hs-CRP are not independently related to artery stiffening.</p>
