While our analysis showed that aspirin may have different effects in men and women, the relatively small number of heart attacks among women and strokes among men suggest that more research is needed to better understand any differences in cardiovascular response to aspirin.

Further research is required to translate these findings into an improvement of health-care quality.

Aspirin has been used for many years, it is well-understood, effective, inexpensive and widely available.

This is good news, because many of the past studies of the effect of aspirin in preventing cardiovascular events looked only at men, so physicians were reluctant to prescribe aspirin for women because there was little data.

There are many disparities in health care, and this analysis has uncovered another area of concern. It is crucial that we implement or enhance systems that help protect against these disparities and improve the quality of care for all patients.

While the medical community is very proficient at treating complex illnesses like heart disease, there still remain disparities in the delivery of that care that needs to be addressed.

We now know with certainty that Aspirin is effective in both men and women in reducing cardiovascular events.

For this reason, while we believe that many more people could benefit from taking aspirin, it is important for patients and their physicians to discuss the issue and weigh the benefits and potential drawbacks to this therapy.
