Abstract

Background. Intake of n-3 polyunsaturated fatty acids (n-3 PUFA) either from natural sources or dietary supplementation is inversely associated with atherothrombosis. Aim. A double-blind pilot study was designed to address the impact of n-3 PUFA on atherosclerosis, haemostasis and vascular status in patients with combined hyperlipoproteinemia. Methods. Carotid intima-media thickness (C-IMT), texture of intima-media complex (T-IMC), lipids and platelet function were evaluated in 64 patients with combined hyperlipoproteinemia who received placebo or n-3 PUFA (6 g/day) for 2 years. C-IMT and T-IMC were assessed by B-mode ultrasound. Lipids and platelet function were determined by validated methods. Results. C-IMT increased in placebo, but not in n-3 PUFA group with respect to baseline. In contrast T-IMC decreased in n-3 PUFA, but not in placebo; in both cases, however, treatment effect did not reach statistical significance. A fall of triglycerides, concomitant to a rise of high- and low-density lipoprotein cholesterol (HDL and LDL), was observed in the active treated group. Platelet function was significantly reduced by n-3 PUFA. Conclusions. Results show a favourable effectiveness of n-3 PUFA on IMT progression and T-IMC that deserves to be confirmed in larger studies. Despite the small sample size, the beneficial effect of n-3 PUFA on platelet function, triglycerides and HDL-C is clearly highlighted.
