AIM: To analyze the use of oral anticoagulants in elderly patients with atrial fibrillation in clinical practice.
PATIENTS & METHODS: Cross-sectional and multicenter study performed in atrial fibrillation patients ≥75 years treated with oral anticoagulants ≥3 months.
RESULTS: 837 patients (83.0 ± 5.0 years; CHA2DS2-VASc 5.0 ± 1.4; HAS-BLED 2.1 ± 0.9; 70.8% vitamin K antagonists; 29.2% direct oral anticoagulants [DOACs]) were included. Poor adherence was observed in 27.9% of patients. Higher scores in the Pfeiffer's test and FRAIL scale were associated with poorer adherence. Among patients treated with DOACs, 62.3% received the lower doses. Having high CHADS2 score and being older were associated with the use of low doses.
CONCLUSION: 28% of patients had a poor adherence to anticoagulant treatment. 62% of patients were treated with the lower doses of DOACs.
