<p>Aim. To assess prescribing structure, efficacy and safety of antithrombotic therapy in in-patients with permanent atrial fibrillation (AF).</p><p>Material and methods. Simple non-comparative retrospective descriptive one stage pharmacoepidemiological study was performed on the basis of analysis of 263 case histories of patients with permanent AF admitted to cardiology department of a general hospital.</p><p>Results. All patients were stratified into three groups depending on the value of the index CHA2DS2-VASc. Antithrombotic therapy was evaluated in each group. 1% patients (n=3) had minimal stroke probability, so there was no need for antithrombotic therapy. 6% (n=15) patients with AF had 1 point according to CHA2DS2-VASc scale. Acetylsalicylic acid was prescribed to 0.7% of cases (n=2), warfarin – to 5% (n=12). High risk of thromboembolic complications (CHA2DS2-VASc≥2) was revealed in 93% patients (n=245), 65% (n=172) of them received warfarin.</p><p>Conclusions. Antithrombotic therapy was administered for the vast majority of patients with AF (97.7%). Antiplatelet drugs were used in 25.4% of cases, including for patients with high risk of thromboembolic complications. Warfarin was prescribed in 70.3%. However, target level of hypocoagulation has been achieved in 51% patients only.</p>
