This study found that high LC n-3 PUFA concentrations, measured through dietary intake or circulating biomarkers, are associated with a lower risk of developing HF.
Aims: Adequate intake of long-chain (LC) omega-3 polyunsaturated fatty acids (n-3 PUFAs) is considered important for cardiovascular health. However, the effects of LC n-3 PUFAs on the risk of heart failure (HF1 remain unclear. This systematic review and meta-analysis aimed to determine the role of LC n-3 PUFAs in the incidence of HF. Materials and Methods: Electronic databases were searched for studies up to 31 July 2021. Studies were included for the meta-analysis if they reported the adjusted associations between different dietary intakes or circulating concentrations of LC n-3 PUFAs and the risk of HF. A random-effect model was used to calculate the pooled estimated hazard ratios (HRs) and 95% confidence intervals (Cis) for higher LC n-3 PUFA concentrations. Results: Thirteen studies were included in the meta-analysis. Eight studies comprising 316,698 individuals (11,244 incident HF cases), with a median follow-up of 10.7years, showed that a higher dietary intake of LC n-3 PUFAs was associated with a lower risk of HF (highest versus lowest quintile: HR=0.84, 95% CI=0.75-0.94). Six studies, comprising 17,163 participants (2520 HF cases) with a median follow-up of 9.7years, showed that higher circulating LC n-3 PUFA concentrations were associated with a lower risk of HF (highest versus lowest quintile: HR=0.59, 95% CI=0.39-0.91). Higher circulating docosahexaenoic acid concentrations were associated with a decreased risk of HF (top versus bottom quintile: HR=0.44, 95% CI =0.26-0.77). The associations between eicosapentaenoic acid (HR=0.58, 95% CI=0.26-1.25), docosahexaenoic acid (HR=0.66, 95% CI=0.24-1.82), and the risk of HF were not significant. Conclusion: High LC n-3 PUFA concentrations measured by dietary intake or circulating biomarkers are associated with a lower risk of developing HF.
