Stroke, prevention and control, Atrial fibrillation

An observational cross-sectional study evaluating the use of re-sources and the sociodemographic and clinical characteristics of patients diagnosed with non-valvular atrial fibrillation with a risk of stroke or systemic embolism on anticoagulant therapy and treated in primary care centers

Trial purpose

This is a retrospective observational study to describe the sociodemographic and clinical characteristics of patients diagnosed with non-valvular atrial fibrillation (NVAF) at risk of stroke or systemic embolism, who at least three months ago changed their anticoagulant therapy, due to any clinical situation, and are currently on treatment with a direct oral anticoagulant (DOAC)

Key Participants Requirements

Age

18 - N/A
  • - Patients ≥18 years of age diagnosed with non-valvular atrial fibrillation with a risk of stroke or systemic embolism treated in primary care centres.
    - Patients on regular treatment with anticoagulants who have changed their therapeutic regimen due to any clinical situation and have been on treatment with a direct oral anticoagulant for at least three months before being recruited (date of signing the in-formed consent).
    - Patients whose first direct oral anticoagulant prescription is written by the specialist (cardiologist, haematologist, internist, etc.) and who are followed in primary care.
    - Patients who have given their informed consent in writing.
