In 2002, the U.S. Preventive Services Task Force (USPSTF) strongly recommended that primary care clinicians discuss preventive aspirin use with adults at increased risk of cardiovascular events. Four years later, the National Commission on Prevention Priorities (NCPP) ranked counseling for aspirin use the number one priority on its list of the most effective clinical preventive services. According to the NCPP, if the percentage of eligible patients using aspirin (then estimated to be about 50 percent) increased to 90 percent, 45,000 additional lives could be extended each year.
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 ofAmerican 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.
