    Abstract

    Background. Mild renal insufficiency has recently been recognized as an important risk factor for cardiovascular disease (CVD). The mechanisms underlying this association are incompletely understood. Increased left ventricular mass (LVM) is an independent risk factor for CVD, which is particularly common in end-stage renal disease (ESRD) and which has been shown to be associated with mild renal insufficiency. Increased arterial stiffness has also been shown to be an independent risk factor for CVD in ESRD and has also been associated with mild renal insufficiency. We hypothesized that the association between mild renal insufficiency and increased LVM could be mediated through increased arterial stiffness, and that this may be one of the pathways linking mild renal insufficiency to CVD. We therefore investigated, in a cross-sectional population-based study, the influence of increased arterial stiffness on the association between renal function and LVM. Methods. The study population consisted of 742 elderly individuals (373 men and 369 women). Renal function was estimated by the serum creatinine level in μmol/L; by the Cockcroft-Gault formula in mL/min and by the Modification of Diet in Renal Disease (MDRD) formula. LVM was obtained by echocardiography. Results. The mean estimates of renal function in men and women were, respectively, 103.7 (SD 17.0) and 86.8 (SD 11.2) μmol/L for the serum creatinine level; 63.4 (SD 12.9) and 61.4 (SD 11.0) mL/min/1.73 m
