Aspirin has different benefits to men and women Washington: Aspirin can significantly reduce the risk of stroke, heart attack and death due to cardiovascular disease in both men and women, according to a new meta-analysis of more than 95,000 patients by a Duke University Medical Center cardiologist. However, the researchers found, the major reasons for the risk reduction differed between the sexes. For men, aspirin lowered the risk of a heart attack, while in women, aspirin reduced the risk of a stroke. The use of aspirin, however, also carries an increased risk of bleeding among both sexes, the study found. The results of the new analysis lead the researchers to recommend that all patients and physicians should discuss the benefits and drawbacks of regularly taking aspirin as a preventative measure against cardiovascular events. "Aspirin is a drug that has been used for many years - it is well-understood, effective, inexpensive and widely available," said Duke cardiology fellow Jeffrey Berger, M.D, first author of a paper published Jan. 18, 2006, in the Journal of the American Medical Association. He performed much of the research while at Beth Israel Medical Center, New York, under senior author cardiologist David Brown, M.D. "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," Berger continued. "But now, the combined data of recent trials involving women demonstrates that women can benefit just as much from aspirin therapy as men." Berger
emphasized that more healthy men and women who can tolerate aspirin should
be taking the medication for the prevention of cardiovascular disease.
It is estimated that fewer than five percent of the population suffers
from the known gastrointestinal side effects of aspirin or are allergic
to it, meaning that many more serious cardiovascular events could be prevented
if aspirin was more widely used, Berger said However, the routine use
of aspirin does not come without potential risks, especially in terms
of major bleeding episodes. The analysis found that routine aspirin use
for an average of 6.4 years would lead to 2.5 major bleeding events per
1,000 women and 3 major bleeding events per 1,000 men.
