Renal function in patients receiving long-term warfarin therapy: A five-year prospective follow-up
Aim. To investigate the prognostic value of renal function and to estimate glomerular filtration rate (GFR) changes during a 5-year follow-up of patients receiving warfarin therapy.

| Summary: | Aim. To investigate the prognostic value of renal function and to estimate glomerular filtration rate (GFR) changes during a 5-year follow-up of patients receiving warfarin therapy. Subjects and methods. 200 patients (124 men, 76 women) mainly from a group at high risk for thromboembolic events (mean CHA2DS2-VASc scores, 3.25±1.89) were examined. The patients’ mean age was 62.3±9.4 years; the follow-up period was 5 years. 74% of the patients received warfarin monotherapy (international normalized ratio (INR) 2.0 to 3.0); 36% took vitamin K antagonists in combination with one or two antiplatelet agents. The CKD-EPI formula was used to estimate GFR in all the patients at baseline and throughout the investigation once a year. Results. GFR less than 70.9 ml/min/1.73 m2 was found to be a predictor of fatal and nonfatal thrombotic events. The decreased GFR was unassociated with the development of major and clinically relevant hemorrhagic complications within 5 years of warfarin therapy. The initial decline in renal function (GFR |
