At that time, the benefits of aspirin use in men and women were assumed to be the same. However, an updated USPSTF recommendation statement published in the June 15th issue of American Family Physician indicates that aspirin use actually prevents heart attacks in men, but ischemic strokes in women. In addition, physicians and patients must weigh the benefits of reduced cardiovascular risk with the risk of gastrointestinal bleeding events, and use shared decision making when these risks are closely balanced.
To further complicate matters, a 2009 meta-analysis published in the journal The Lancet questioned the value of aspirin for primary prevention, concluding that for patients who without a history of cardiovascular disease, "aspirin is of uncertain net value." In response, family physicians and USPSTF members Ned Calonge and Michael LeFevre wrote an editorial that concluded, "There is not a simple message for aspirin prophylaxis as a primary preventive strategy, and we need to consider gender, age, and the associated balance of potential risks and benefits to provide the best advice and preventive care for our patients."
The debate continues with two thought-provoking editorials in the June 15th issue of AFP. Alison L. Bailey and colleagues caution that routine aspirin use is not justified for primary prevention in adults at low risk of CVD. On the other hand, W. Fred Miser asserts that the main issue regarding aspirin for primary prevention continues to be underuse in appropriate-risk patients.
So which is the bigger problem, overuse or underuse?
The above is a slightly edited version of a post that was originally published on the AFP Community Blog.
