Hypothesis

Does the use of nonsteroidal anti-inflammatory drugs (NSAIDs) affect the cardioprotective effects of hormone therapy in postmenopausal women?

Conclusion

The study suggests that NSAIDs may undermine the cardioprotective effects of hormone therapy in peri- and postmenopausal women.

Supporting Evidence

  • Current use of hormone therapy was associated with a lower risk of heart attack than non-use.
  • The odds ratio for heart attack among users of hormone therapy and NSAIDs was 1.50.
  • The study included a large sample size of 1,673 cases and 7,005 controls.

Takeaway

This study found that taking hormone therapy might help protect women's hearts, but if they also take certain painkillers, it might not work as well.

Methodology

The study used a population-based epidemiological approach, analyzing data from the General Practice Research Database to assess the interaction between hormone therapy and NSAIDs on myocardial infarction incidence.

Potential Biases

Potential biases include healthy user bias and compliance bias due to the nature of observational studies.

Limitations

The study is observational and may be affected by unrecognized confounding factors.

Participant Demographics

Women aged 50-84 years, with 1,673 cases of myocardial infarction matched against 7,005 controls.
