Trial Purpose
This prospective observational study is to assess the predictive factors of poor control of international normalized ratio (INR) to determine the treatment strategies received by patients with a poor control of INR in real-life clinical practice and to explore the effectiveness and safety of these strategies in patients with non-valvular atrial fibrillation who start vitamin K antagonist (VKA) treatment
Inclusion Criteria
- Patients aged ≥ 18 years. - Patients with a diagnosis of nonvalvular atrial fibrillation according to the criteria of the Spanish Agency of Medicines and Medical Devices (AEMPS) (2013) who are treated in cardiology practices. - Patients about to start treatment with a vitamin K antagonist or who are in the first two months of treatment. - Patients for whom access to at least 80% of INR tests performed during treatment with vitamin K antagonists is expected to be available. - Patients with the mental and physical capacity to complete the study questionnaires and give their informed consent to participate in the study.
Exclusion Criteria
- Patients with mitral stenosis or another significant valve disease for which specific treatment is scheduled or has already been performed (prosthesis or valvuloplasty). - Patients hospitalised at the time of inclusion in the study. - Patients with a life expectancy of less than 13 months. - Patients who are participating in a clinical trial. - Patients receiving double antiplatelet therapy.
