Abstract

BACKGROUND: Antioxidant vitamin (vitamin E, beta-carotene, and vitamin C) are widely used for preventing major cardiovascular outcomes. However, the effect of antioxidant vitamin on cardiovascular events remains unclear. METHODOLOGY AND PRINCIPAL FINDINGS: We searched PubMed, EmBase, the Cochrane Central Register of Controlled Trials, and the proceedings of major conferences for relevant literature. Eligible studies were randomized controlled trials that reported on the effects of antioxidant vitamin on cardiovascular outcomes as compared to placebo. Outcomes analyzed were major cardiovascular events, myocardial infarction, stroke, cardiac death, total death, and any possible adverse events. We used the I(2) statistic to measure heterogeneity between trials and calculated risk estimates for cardiovascular outcomes with random-effect meta-analysis. Independent extraction was performed by two reviewers and consensus was reached. Of 293 identified studies, we included 15 trials reporting data on 188209 participants. These studies reported 12749 major cardiovascular events, 6699 myocardial infarction, 3749 strokes, 14122 total death, and 5980 cardiac deaths. Overall, antioxidant vitamin supplementation as compared to placebo had no effect on major cardiovascular events (RR, 1.00; 95%CI, 0.96-1.03), myocardial infarction (RR, 0.98; 95%CI, 0.92-1.04), stroke (RR, 0.99; 95%CI, 0.93-1.05), total death (RR, 1.03; 95%CI, 0.98-1.07), cardiac death (RR, 1.02; 95%CI, 0.97-1.07), revascularization (RR, 1.00; 95%CI, 0.95-1.05), total CHD (RR, 0.96; 95%CI, 0.87-1.05), angina (RR, 0.98; 95%CI, 0.90-1.07), and congestive heart failure (RR, 1.07; 95%CI, 0.96 to 1.19). CONCLUSION/SIGNIFICANCE: Antioxidant vitamin supplementation has no effect on the incidence of major cardiovascular events, myocardial infarction, stroke, total death, and cardiac death.

  • Several vitamins and nutrients associate with lower CVD risk in observational studies, but trials of supplements, including folate, B-vitamins, beta-carotene, vitamin C, vitamin E, and selenium, have shown no significant effects on atherosclerosis progression or CVD events.

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.
