Brief Summary

DAN-RELEASE is a national, randomized, registry-based trial including 7,000 participants in Denmark. The trial aims to determine whether discontinuation of long-term aspirin therapy is non-inferior to continued aspirin therapy in older adults with stable ischemic heart disease. Long-term aspirin therapy is recommended for patients with established ischemic heart disease. However, among clinically stable patients years after percutaneous coronary intervention (PCI), coronary artery bypass grafting (CABG), or myocardial infarction (MI), the evidence supporting lifelong aspirin therapy is limited. At the same time, the risk of serious bleeding increases with age. DAN-RELEASE will therefore compare aspirin discontinuation with continued aspirin therapy in adults aged 65 years or older with stable ischemic heart disease who have remained free from ischemic events for at least two years. The trial will assess whether discontinuing aspirin is non-inferior to continued treatment with respect to cardiovascular and bleeding outcomes.

Outcome Measures

Primary Outcomes (1)

  • Hierarchical Composite of Cardiovascular and Bleeding Events

    A hierarchical composite endpoint using a win-ratio framework combining cardiovascular death, fatal bleeding, intracranial bleeding, Myocardial infarction, ischemic stroke, and bleeding events (BARC 3-5).

    From randomization until the end of the study, with a minimum follow-up of 1 year

Secondary Outcomes (13)

  • Cardiovascular Death

    From randomization until the end of the study, with a minimum follow-up of 1 year

  • Fatal Bleeding (BARC Type 5)

    From randomization until the end of the study, with a minimum follow-up of 1 year

  • Intracranial Bleeding (BARC Type 3c)

    From randomization until the end of the study, with a minimum follow-up of 1 year

  • Ischemic Stroke

    From randomization until the end of the study, with a minimum follow-up of 1 year

  • Myocardial Infarction

    From randomization until the end of the study, with a minimum follow-up of 1 year

  • +8 more secondary outcomes
