Direct oral anticoagulants like edoxaban and apixaban help prevent stroke in atrial fibrillation (AF) patients. Edoxaban showed a lower risk of stroke or embolism compared to apixaban in Italian patients, especially older adults.
Area of Science:
- Cardiology
- Pharmacology
- Public Health
Background:
- Direct oral anticoagulants (DOACs) are recommended for thromboembolism prevention in atrial fibrillation (AF).
- Randomized controlled trials (RCTs) have not directly compared edoxaban and apixaban.
- Real-world data is crucial for comparing these DOACs in clinical practice.
Purpose of the Study:
- To retrospectively compare clinical outcomes between edoxaban and apixaban in Italian AF patients.
- To evaluate effectiveness (ischemic stroke/systemic embolism) and safety (major bleeding).
- To analyze outcomes in the overall population and by age group (≥80 years and <80 years).
Main Methods:
- Utilized the Italian IQVIA Longitudinal Patient Database (January 2016-December 2021).
- Included adult patients with AF newly initiating edoxaban or apixaban.
- Employed propensity score matching to balance baseline characteristics between treatment groups.
- Calculated incidence rates per 100 person-years and hazard ratios (HRs) with 95% confidence intervals (CIs).
Main Results:
- 8,444 patients were identified; 3,188 received edoxaban and 5,256 received apixaban.
- After matching, the risk of ischemic stroke/systemic embolism (IS/SE) was significantly lower for edoxaban vs. apixaban in the overall population (HR: 0.78, 95% CI: 0.61-0.99).
- Edoxaban also showed a significantly lower IS/SE risk in patients aged ≥80 years (HR: 0.61, 95% CI: 0.44-0.86).
- No significant differences in major bleeding (MB) risk were observed between the two drugs.
- No significant differences in IS/SE or MB risk were found in patients <80 years.
Conclusions:
- Edoxaban demonstrated a significantly lower risk of IS/SE compared to apixaban in the overall AF patient population.
- This benefit was particularly pronounced in patients aged ≥80 years.
- Edoxaban use was not associated with an increased risk of major bleeding compared to apixaban in these patient groups.
