1、Aspirin for the Prevention of Cardiovascular Disease: U.S. Preventive Services Task Force Recommendation StatementU.S. Preventive Services Task Force*Description: Update of the 2002 U.S. Preventive Services Task Force (USPSTF) recommendation about the use of aspirin for the prevention of coronary he
2、art disease.Methods: Review of the literature since 2002, focusing on new evi- dence on the benefits and harms of aspirin for the primary prevention of cardiovascular disease, including myocardial infarction and stroke. The new evidence was reviewed and synthesized according to sex.Recommendations:
3、Encourage men age 45 to 79 years to use aspirin when the potential benefit of a reduction in myocardial infarctions outweighs the potential harm of an increase in gastro- intestinal hemorrhage. (A recommendation) Encourage women age 55 to 79 years to use aspirin when the potential benefit of a reduc

(A recommendation) Evidence is insufficient to assess the balance of benefits and harms of aspirin for cardiovascular disease prevention in men and women 80 years or older. (I statement) Do not encour
5、age aspirin use for cardiovascular disease preven- tion in women younger than 55 years and in men younger than 45 years.

6、t www.annals.org).The U.S. Preventive Services Task Force (USPSTF) makes recommendations about preventive care services for patients without recognized signs or symptoms of the target condition. It bases its recommendations on a systematic review of theevidence of the benefits and harms and an asses
7、sment of the netbenefit of the service. The USPSTF recognizes that clinical or policy decisions in- volve more considerations than this body of evidence alone. Cli- nicians and policymakers should understand the evidence but in-dividualize decision making to the specific patient or situation.SUMMARY
8、 OFRECOMMENDATION ANDEVIDENCE The USPSTF recommends the use of aspirin for menage 45 to 79 years when the potential benefit due to a reduction in myocardial infarctions outweighs the poten- tial harm due to an increase in gastrointestinal hemorrhage. See the Clinical Considerations section for discu
9、ssion ofbenefits and harms. This is an A recommendation. The USPSTF recommends the use of aspirin forwomen age 55 to 79 years when the potential benefit of a reduction in ischemic strokes outweighs the potential harm of an increase in gastrointestinal hemorrhage. See the Clin-ical Considerations sec
10、tion for discussion of benefits and harms. This is an A recommendation. The USPSTF concludes that the current evidence isinsufficient to assess the balance of benefits and harms of aspirin for cardiovascular disease prevention in men and women 80 years or older. This is an I statement. See the Clini
11、cal Considerations section for suggestions for practice regarding the I statement. The USPSTF recommends against the use of aspirin for stroke prevention in women younger than 55 years and for myocardial infarction prevention in men younger than 45 years. This is a D recommendation. Figure 1 (page 4

See the Clinical Consid- erations section.Benefits of Preventive Medication The USPSTF found good evidence that aspirin de- creases th
