Brief Summary
ADAPTABLE is a pragmatic clinical trial in which 15,000 patients who are at high risk for ischemic events will be randomly assigned in a 1:1 ratio to receive an aspirin dose of 81 mg/day vs. 325 mg/day. Study participants will be enrolled over 38 months. Maximum follow-up will be 50 months. The purpose of the study is to identify the optimal dose of aspirin for secondary prevention in patients with Atherosclerotic cardiovascular disease (ASCVD). The primary endpoint is a composite of all-cause death, hospitalization for MI, or hospitalization for stroke. The primary safety endpoint is hospitalization for major bleeding with an associated blood product transfusion.

Eligibility Criteria
You may qualify if:
- Known atherosclerotic cardiovascular disease (ASCVD), defined by a history of prior myocardial infarction, prior coronary angiography showing ≥75% stenosis of at least one epicardial coronary vessel, or prior coronary revascularization procedures (either PCI or CABG), or history of chronic heart disease, CAD, ASCVD
- Age ≥ 18 years
- No known safety concerns or side effects considered to be related to aspirin, including
- No history of significant allergy to aspirin such as anaphylaxis, urticaria, or significant gastrointestinal intolerances
- No history of significant GI bleed within the past 12 months
- Significant bleeding disorders that preclude the use of aspirin
- Access to the Internet. In the event that the CDRNs are notified that a cohort of patients without internet access can be included, then patient agreement will be obtained during the consent process to provide follow-up information by telephone contact with the DCRI Call Center.
- Not currently treated with an oral anticoagulant - either warfarin or a novel anticoagulant (dabigatran, rivaroxaban, apixaban, edoxaban) - and not planned to be treated in the future with an oral anticoagulant for existing indications such as atrial fibrillation, deep venous thrombosis, or pulmonary embolism.
- Not currently treated with ticagrelor and not planned to be treated in the future with ticagrelor.
- Female patients who are not pregnant or nursing an infant
- Estimated risk of a major cardiovascular event (MACE) \> 8% over next 3 years as defined by the presence of at least one or more of the following enrichment factors:
- Age \> 65 years
- Serum creatinine \> 1.5 mg/dL
- Diabetes mellitus (Type 1 or Type 2)
- vessel coronary artery disease
- +6 more criteria
You may not qualify if:
- Patients and sites interested in participating must be part of the listed health systems collaborators.
