OBJECTIVE: C-type natriuretic peptide (CNP) is a paracrine molecule with effects on endothelial integrity, vascular tone and atherosclerotic process. Arterial stiffness, wave reflections, endothelial dysfunction and carotid intima-media thickness (IMT) are predictors of cardiovascular events. We investigated whether CNP is related to arterial structure and function in men. METHODS: We evaluated arterial structural and functional characteristics in 117 consecutive men (mean age 57.3 + or - 9.2 years), with and without cardiovascular risk factors, who had no established cardiovascular disease. Arterial elastic properties were evaluated with carotid-femoral pulse wave velocity (PWV), wave reflections with augmentation index (AIx), endothelial function with flow-mediated dilatation of the brachial artery (FMD) and early atherosclerosis with carotid IMT. Amino-terminal proCNP (NT-proCNP) was assessed in venous blood. RESULTS: The number of cardiovascular risk factors was inversely related to levels of NT-proCNP (P<0.01) and there was a progressive increase in Framingham risk score according to decreasing tertiles of NT-proCNP (P<0.001). In multivariable regression analysis NT-proCNP exhibited significant negative associations with PWV and IMT and positive association with FMD (all P<0.05) that were independent of age, blood pressure, smoking habits, body mass index, blood glucose, total triglycerides, low-density lipoprotein and endothelin-1 or high-sensitivity C-reactive protein. There was no relation between NT-proCNP and AIx. CONCLUSION: The present study is the first to demonstrate in a global arterial approach relationship between CNP and functional and early structural arterial changes. These findings elucidate pathophysiological links and may have important clinical implications for the estimation of cardiovascular risk in men. Copyright 2010 Elsevier Ireland Ltd.
