Antioxidant supplements, like vitamin E, may benefit healthy individuals in preventing cardiovascular disease, despite inconclusive results in high-risk patients. Further research is needed to clarify their role in disease prevention.

Area of Science:

  • Biochemistry
  • Cardiovascular Science
  • Nutritional Science

Background:

  • Oxidative lipid modification is implicated in atherosclerosis, but clinical evidence has been inconclusive.
  • Recent studies suggest antioxidant supplements may not benefit high-risk cardiovascular patients.
  • Epidemiological data indicates potential benefits of antioxidants, particularly vitamin E, in healthy populations.

Purpose of the Study:

  • To clarify the role of antioxidants in disease prevention, considering conflicting evidence.
  • To evaluate the efficacy of antioxidant supplements in cardiovascular health.
  • To address uncertainties regarding antioxidant mechanisms and interactions in atherogenesis.

Main Methods:

  • Review of in vitro findings and animal models.

  • Analysis of clinical intervention studies in high-risk patients.
  • Examination of epidemiological studies on antioxidant supplementation.

    • Main Results:

    • Clinical trials in high-risk patients yielded inconclusive results regarding antioxidant benefits.
    • Epidemiological studies suggest protective effects of vitamin E in healthy subjects.
    • Complex factors like antioxidant pro-oxidant potential and plaque microenvironment may affect efficacy.

    Conclusions:

    • The overall benefit of antioxidant supplements for cardiovascular disease prevention remains uncertain.
    • Evidence suggests a potential benefit in healthy individuals, contrasting with high-risk groups.
    • Further investigation is crucial to elucidate the precise role of antioxidants in disease prevention and optimize their use.
