Abstract

Abstract:

Objective The aim of this study was to prospectively evaluate the efficacy and safety of rivaroxaban in the treatment of elderly patients with non-valvular atrial fibrillation (NVAF) who had a HASBLED score≥3. Methods A total of 90 patients over 75 years old with NVAF (HASBLED score≥3) treated with rivaroxaban from February to September in 2023, they were divided into low dose group (10 mg/d) and conventional dose group (15 mg/d). A 6-month follow-up was performed, the end points of primary efficacy were ischemic stroke, peripheral arterial embolism. The major bleeding was as a safety end point, including clinically significant minor bleeding, small bleeding as subcutaneous congestion, gingival bleeding, hematuria, occult blood positive stool, conjunctival bleeding. Results The scores of CHA2DS2-VASc and HASBLED in low dose group were significantly higher than those in conventional dose group (P<0.05). There was no significant difference in coagulation index between the two groups before treatment (P>0.05). During the 6-month follow-up, no new ischemic stroke and peripheral embolic events were observed in the low dose group and conventional dose group. There were 3 cases of occult blood positive stool, 2 cases of gingival bleeding and 3 cases of subcutaneous ecchymosis in conventional dose group. Conclusion Low-dose rivaroxaban anticoagulation therapy is effective and safety in elderly NVAF patients who HASBLED score ≥3, which provides theoretical basis for clinical application.
