What is the recommendation for using prophylactic aspirin for adults 40-70 years of age?
The recommendation for using prophylactic aspirin for adults 40-70 years of age is a Class IIb recommendation. It is suggested to use aspirin at doses of less than 100 mg daily for primary prevention as meta-analyses suggest that the ASCVD risk benefit for low-dose aspirin is equivalent to that for high-dose aspirin, but the bleeding risk is higher with high-dose aspirin.
