Aspirin for Women: Yes or No?

Study Renews Controversy, Shows Fewer Deaths in Women on Aspirin

March 26, 2007 - Last year, researchers told women that regular aspirin won't prevent heart disease or cancer. Now a new study says it does -- for some women, at least.

The new findings come from the Nurses' Health Study, a 30-year-long study of nearly 80,000 women. The study suggests that women who regularly take low-dose aspirin (81 milligrams of baby aspirin) or moderate-dose aspirin (325 milligrams of adult aspirin) are less likely to die than those who don't take aspirin.

The study shows that women who took low- or moderate-dose aspirin were:

Women who regularly took high-dose aspirin -- more than 14 adult-strength tablets a week -- did not get a health benefit. Instead, they were 43% more likely to die from hemorrhagic stroke compared with those who never took aspirin. Hemorrhagic stroke is stroke due to bleeding in the brain.

Women got a heart benefit from aspirin after about five years of use. The cancer benefit didn't appear before 10 years of regular aspirin use.

Older women and women with pre-existing risk factors for heart disease got the largest benefit from regular low- or moderate-dose aspirin.

Andrew T. Chan, MD, MPH, assistant professor of medicine at Harvard Medical School, and colleagues report the findings in the March 26 issue of Archives of Internal Medicine.

"There are suggestions here that there is a subgroup of women for whom regular aspirin makes sense," Chan tells WebMD. "But no one should take aspirin therapy on her own. This still requires a thorough discussion of individual risks and benefits with a doctor."

No Aspirin for Women

The evidence remains strong that daily low-dose aspirin cuts a man's risk of heart disease and stroke -- although the drug does increase a man's risk of ulcers and gastrointestinal bleeding.

But the new study by Chan and colleagues isn't as convincing as last year's report from the huge Women's Health Study, suggests an editorial accompanying the Chan report.
