Increased arterial stiffness has been found in patients with chronic high-grade inflammatory diseases. Whether mitigation of low-grade systemic inflammation, through a low-cholesterol/low-saturated fat diet, may have a role in improving arterial stiffness is still untested. We investigated whether variations in blood lipids and plasma C-reactive protein induced by low-cholesterol/low-saturated fat diet are associated with variations in large-artery stiffness in hypercholesterolemia. Thirty-five patients with primary hypercholesterolemia and 15 normal control subjects were recruited for the study. Hypercholesterolaemic patients followed an 8-week low-cholesterol/low-saturated fat diet (30% total fat, 5% saturated fat, cholesterol <200mg/daily). Anthropometric characteristics, blood lipids, plasma C-reactive protein and arterial stiffness were measured at baseline and after the diet. Arterial stiffness and C-reactive protein levels were higher in hypercholesterolaemic patients than in controls. Significant reductions in body weight (2 kg, 3%), plasma total cholesterol (13.4mg/dl, 5.3%), low-density lipoprotein cholesterol (11.2 mg/dl, 6.4%), C-reactive protein (0.7 mg/l, 39%) and arterial stiffness (from 8.9 ± 2.0 to 8.1 ± 1.9 m/s, 11%) were achieved among hypercholesterolaemic patients after the 8-week diet (P < 0.05 for all). Bivariate correlations and multivariate analysis showed reduction in arterial stiffness after short-term diet to be associated with reduction of plasma C-reactive protein levels (r = 0.59, β = 0.38, P<0.05 for both). © 2004, European Society of Cardiology.
