Effect of Omega-3 fatty acid supplementation on markers of platelet and endothelial function in patients with peripheral arterial disease
Abstract
Objective: Omega-3 fatty acids have been shown to reduce platelet and endothelial activation in patients with or at risk of cardiac disease. We aimed to determine if Omega-3 fatty acid supplementation in addition to best medical therapy can reduce the increased platelet and endothelial activity that is present in patients with intermittent claudication.
Methods: One hundred and fifty patients who were receiving aspirin and statin therapy were recruited into a randomised cross-over double blind study involving 6 week supplementation with OMACOR fish oil (850-882 mg eicosapentaenoic and docosahexaenoic acid) versus placebo. A 12 week washout period occurred between treatments. Patients with diabetes were excluded. For each outcome a random effects model was fitted in which treatment and period were fixed effects and patients were random effects.
Results: Omega-3 supplementation had no effect on the primary outcome measure von Willebrand factor. Similarly Omega-3 supplementation resulted in no change in unstimulated or stimulated P-selectin expression and fibrinogen binding, or platelet aggregation (Ultegra point of care). Pulse wave velocity was also unchanged. High-sensitivity C-reactive protein, s-ICAM and IL-6 were also unchanged.
Conclusion: Supplementation with Omega-3 fatty acids had no affect on platelet and endothelial activation or markers of inflammation in patients with peripheral arterial disease.
