Outcome Measures

Primary Outcomes (2)

  • Stroke, systemic or pulmonary arterial thromboembolism and intracardiac thrombosis.

    The composite endpoint of all-cause stroke, systemic and pulmonary embolism and intracardiac thrombosis

    up to 58 months

  • Major bleeding

    Defined as clinically overt bleeding that is associated with: * A fall in hemoglobin of 2 g/dL or more * A transfusion of ≥2 units of packed red blood cells or whole blood * Bleeding in a critical site: intracranial, intraspinal, intraocular, pericardial, intraarticular, intramuscular with compartment syndrome, retroperitoneal * Death (fatal bleeding)

    up to 58 months

Secondary Outcomes (5)

  • Transient ischemic attack

    up to 58 months

  • Myocardial infarction

    up to 58 months

  • Death from cardiovascular causes

    up to 58 months

  • Τhe composite of major and clinically relevant nonmajor bleeding

    up to 58 months

  • Τhe composite of stroke, systemic or pulmonary arterial thromboembolism and intracardiac thrombosis, transient ischemic attack, myocardial infarction, or cardiovascular death

    up to 58 months

Other Outcomes (3)

  • General quality of life

    Baseline

  • Apixaban persistence

    up to 58 months

  • Apixaban adherence

    up to 58 months

Study Arms (1)

Adults with CHD & non-valvular atrial arrhythmias

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodProbability Sample
Study Population

Adult patients with Congenital Heart Disease and Non-Valvular Atrial Arrhythmias who are routinely treated with apixaban (i.e., new or ongoing users) for stroke prevention at any health-care level in Greece

You may qualify if:

  • Male or female patients aged ≥18 years.
  • Presence of congenital heart disease (intracardiac repair, cyanosis, Fontan palliation, or systemic right ventricle or other congenital heart disease).
  • Non-Valvular Atrial Arrhythmia (including at least one electrocardiographically documented episode).
  • Signed written informed consent by the patient for participation in the study and agreement to comply with the medication and the follow-up schedule.

You may not qualify if:

  • moderate-to-severe mitral stenosis or mechanical valves
  • patient unwilling or unable to complete follow-up procedures
