Patients undergoing procedures often interrupt edoxaban. While heparin bridging is not recommended, its use was associated with increased bleeding risk, not reduced thromboembolic events. Bleeding risk factors, not stroke risk, influenced this clinical decision.
Area of Science:
- Cardiology
- Pharmacology
Background:
- Edoxaban interruption is common for procedures.
- Heparin bridging is frequently used despite not being recommended.
- The efficacy and safety of heparin bridging during edoxaban interruption are unclear.
Purpose of the Study:
- To identify factors predicting edoxaban interruption and heparin bridging.
- To evaluate clinical events, including bleeding and thromboembolism, associated with heparin bridging.
- To understand the rationale behind clinicians' decisions to use heparin bridging.
Main Methods:
- Prospective, noninterventional study (Global EMIT-AF/VTE).
- Inclusion of adult patients with atrial fibrillation or venous thromboembolism on edoxaban undergoing procedures.
- Collection of data on edoxaban interruption, heparin bridging, and clinical events.
Main Results:
- Edoxaban was interrupted in 58.5% of procedures.
- Heparin bridging was used in 14.6% of interruptions.
- Higher HAS-BLED scores and high EHRA procedural risk predicted interruption and bridging; CHA2DS2-VASc scores did not.
- Heparin bridging was associated with higher bleeding rates (6.2% vs 3.1%) but not lower thromboembolic risk.
Conclusions:
- Periprocedural heparin use in edoxaban interruption is linked to increased bleeding.
- Bleeding risk factors, rather than stroke risk, appear to drive the decision to use heparin bridging.
- Current practice may not align with recommended guidelines regarding heparin bridging during edoxaban interruption.
