Area of Science:

  • Cardiovascular Science
  • Endocrinology
  • Women's Health

Background:

  • Observational studies suggest estrogen offers protection against coronary heart disease (CHD) in women.
  • The 'estrogen-heart disease hypothesis' has been studied for decades.
  • Despite consistent evidence, clinical trials are essential to validate these findings.

Purpose of the Study:

  • To review the history and evidence supporting the estrogen-heart disease hypothesis.
  • To explain the necessity of clinical trials for postmenopausal estrogen therapy.
  • To present the status of the Postmenopausal Estrogen/Progestin Interventions (PEPI) trial and other ongoing research.

Main Methods:

  • Review of historical studies on the estrogen-heart disease link.
  • Analysis of the rationale for clinical trials in postmenopausal women.
  • Summary of findings from the PEPI trial and related ongoing studies.

Main Results:

  • Observational data consistently indicate a protective effect of estrogen on heart health in women.
  • Clinical trials are crucial to confirm the benefits suggested by observational data.
  • The PEPI trial and other ongoing research are evaluating the role of hormone therapy.

Conclusions:

  • Estrogen's role in cardiovascular protection for women requires rigorous clinical validation.
  • Understanding the benefits and risks of hormone therapy is critical for postmenopausal women.
  • Exploration of nonhormonal primary prevention strategies for heart disease is also important.
