Eur Heart J Cardiovasc PharmacotherPublished

  • randomized trial with a 2 × 2 factorial design
  • double-blind

Study context

Population
Patients with atherosclerotic cardiovascular disease (ASCVD) receiving low-dose aspirin
Planned comparison
enteric-coated vs. chewable aspirin 81 mg daily and (via factorial randomization) to a hybrid strategy to mitigate the adverse effects of air pollution vs. usual care
Primary endpoint
Aspirin randomization: composite of fatal/non-fatal ischaemic stroke, thrombotic/thromboembolic myocardial infarction, and acute limb ischaemia; AIR randomization: additionally other forms of cardiovascular death
Follow-up
Median planned 2 years

No results yet. This paper sets out the design of a trial; its results are to come.
