40 ADA/AHA/ACC: Recommendations for Use of Aspirin for Primary Prevention of CV Events in People With Diabetes Recommendation Low-dose ( mg/d) aspirin use for prevention is reasonable for adults with diabetes and no previous history of vascular disease who are at increased CVD risk and who are not at increased risk for bleeding Aspirin should not be recommended for CVD prevention for adults with diabetes at low CVD risk potential adverse effects from bleeding outweigh potential benefits Low-dose ( mg/d) aspirin use for prevention might be considered for those with diabetes at intermediate CVD risk until further research is available Definition of risk 10-yr risk of CVD events >10% Most men >50, women >60 yrs with smoking, HTN, dyslip, premature CVD fam hx, albuminuria 10-yr CVD risk <5% Men <50, women <60 yrs with no major add l CVD risk factors Younger patients with 1 risk factor Older pts with no risk factors Pts w/ 10-yr CVD risk 5 10% Pignone M, et al.
