Atrial fibrillation with thrombotic complications. Justification of the diagnosis and treatment regimen according to evidence-based medicine (clinical case)

Background. The presence of atrial fibrillation (AF) in patients is associated with a twofold increased risk of all-cause mortality. This is caused not only by fibrillation itself, but also to comorbid pathology and complications of this arrhythmia. Stroke is the most important predictor of high mortality among patients with AF, which occurs 5–6 times more often than with sinus rhythm.
