Fish and n−3 fatty acids for the prevention of fatal coronary heart disease and sudden cardiac death

Abstract

Large observational studies, randomized clinical trials, and experimental studies have evaluated the effects of fish and n-3 fatty acid consumption on fatal coronary heart disease (CHD) and sudden cardiac death (SCD), clinically defined events that most often share the final common pathway of fatal ventricular arrhythmia. These different study designs, each having complementary strengths and limitations, provide strong concordant evidence that modest consumption of fish or fish oil (1-2 servings/wk of oily fish, or approximately 250 mg/d of EPA+DHA) substantially reduces the risk of CHD death and SCD. Pooled analysis of prospective cohort studies and randomized clinical trials demonstrates the magnitude and dose-response of this effect, with 36% lower risk of CHD death comparing 0 and 250 mg/d of EPA+DHA consumption (P < 0.001), but then little additional benefit with higher intakes. Reductions in risk are even larger in observational studies utilizing tissue biomarkers of n-3 fatty acids that more accurately measure dietary consumption. The concordance of findings from different studies also suggests that effects of fish or fish oil on CHD death and SCD do not vary depending on presence or absence of established CHD. The strength and consistency of the evidence, and the magnitude of this effect are each notable. Because more than one-half of all CHD deaths and two-thirds of SCD occur among individuals without recognized heart disease, modest consumption of fish or fish oil, together with smoking cessation and regular moderate physical activity, should be among the first-line treatments for prevention of CHD death and SCD.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
