BACKGROUND: The underlying reasons for the highly inconsistent clinical outcome data for omega-3-polyunsaturated fatty acids (n3-PUFAs) supplementation in patients with cardiac disease have not been understood yet. The aim of this prospective, randomized, double-blind, placebo controlled study was to determine the effects of oral treatment with n3-PUFAs on the anti-oxidant capacity of HDL in heart failure (HF) patients.

METHODS: A total of 40 patients with advanced HF of nonischaemic origin, defined by NT-proBNP levels of >2000 pg/mL, NYHA class III or IV and a LVEF <35% who were on stable optimized medical therapy for ≥3 months, were consecutively enrolled into this prospective, double-blind, placebo-controlled trial and randomized in a 1:1:1 fashion to receive 1 g/day or 4 g/day of n3-PUFA, or placebo, respectively, for 12 weeks.

RESULTS: After 12 weeks of treatment, the anti-oxidant function of HDL, measured by the HDL inflammatory index, was found significantly impaired in the treatment group in a dose-dependent fashion with 0.67 [IQR 0.49-1.04] for placebo vs 0.71 [IQR 0.55-1.01] for 1 g/day n3-PUFA vs 0.98 [IQR 0.73-1.16] for 4 g/day n3-PUFA (P for trend = 0.018).

CONCLUSION: We provide evidence for an adverse effect of n3-PUFA supplementation on anti-oxidant function of HDL in nonischaemic heart failure patients, establishing a potential mechanistic link for the controversial outcome data on n3-PUFA supplementation.
