What is the role of aspirin for primary ASCVD prevention?

* The Conundrum: ASCVD event rates are much lower in the primary prevention than in the secondary prevention population, BUT the bleeding rates are comparable. So in the primary prevention patients, the bleeding risk is just as high, but the propensity for benefit is lower.* The Question: Does low dose aspirin have a place in the primary prevention of ASCVD events.* The Data:* ARRIVE Trial: in moderate risk nondiabetic patients without prior ASCVD events, there was no different in the composite ASCVD end point, but there was an increased risk of bleeding (mostly mild GI bleeding).Thus, in the moderate risk patients –> primary prevention aspirin has an unfavorable risk-benefit profile.The benefit in a higher risk (>10-20% estimated 10-yr risk) remains unclear.* ASCEND Trial: In men and women age ≥ 40yrs with diabetes without prior ASCVD events, there was a modest benefit (NNT = 59 patients for 10 years to prevent 1 major ASCVD event) counterbalanced by a similar magnitude of harm (NNH = 77 patients for 10 years to cause 1 major bleeding event).Thus, in adults with diabetes –> primary prevention aspirin had a neutral risk-benefit profile.* ASPREE Trial: in elderly patients (≥70 years;≥65 years for Hispanic or Black patients) without prior ASCVD events, there was no difference in ASCVD events but there was a significant increase in bl…
