Aim. To study changes in quality of life (QoL) in patients with atrial fibrillation (AF) treated with warfarin after leaving the international clinical trial. Material and Methods. Patients with AF who were managed at cardiology department of the University Hospital participated in the study. Patients of the main group (n=79) completed the international clinical trial with warfarin titration to therapeutic doses and subsequent therapy monitoring at least 1 year . Patients of the control group (n=23) had never taken part in clinical trials. QoL was evaluated with the 36-Item Short-Form Health Survey (SF 36) questionnaire after international clinical trial living or hospital discharge (initially) and in 3, 6 months of follow-up in outpatient clinic. Results. The most significant changes were observed in the first 3 months. In patients of the main group after clinical trial leaving physical component of QoL decreased from 65 (52.0-77.0) to 52 (25.0–55.0) points (p<0.05) and emotional component – from 65 (55.0-70.0) to 60 (50.0–65.0) points (p<0.05). At the same period opposite dynamics was observed in patients of the control group after hospital discharge. Physical component of QoL increased from 55 (25.0-65.0) to 65 (52.0–77.0) points (p<0.05) and emotional component - from 60 (47.5- 65.0) to 70 (60.0–75.0) points (p<0.05). In the next 3 months QoL levels have not changed significantly in patients of the both groups. Conclusion. International clinical trial living affects QoL in patients with AF . The physical component of QoL worsens most significantly.
