Direct Oral Anticoagulants in Atrial Fibrillation: Practical Considerations and Remaining Issues
1Thrombosis Research Unit, Department of Medicine I, Division Hematology, University Hospital "Carl Gustav Carus" Dresden, Dresden, Germany.
Abstract:
Preventing thromboembolic events, while minimizing bleeding risks, remains challenging when managing patients with atrial fibrillation. Despite large and successful trial programs, several clinical concerns remain which commonly relate to fears of over- or underexposure to drugs and unfavorable outcomes. After a short summary of the main phase III trial findings, this short review discusses the evidence and clinical relevance of common clinical concerns (correct direct oral anticoagulant [DOAC] dosing; DOAC in moderate-to-severe renal impairment; and the relevance of fasting, nasogastric tube feeding, or high body mass index) on DOAC plasma levels. Finally, the need for specific DOAC antidotes will be addressed.
Insights
Managing atrial fibrillation patients requires balancing clot prevention and bleeding risks. This review addresses direct oral anticoagulant (DOAC) dosing, renal impairment, and other factors impacting DOAC levels and patient outcomes.
Area of Science:
- Cardiology
- Pharmacology
Background:
- Managing atrial fibrillation (AF) patients involves balancing thromboembolic event prevention with bleeding risks.
- Clinical concerns persist regarding direct oral anticoagulant (DOAC) drug exposure and patient outcomes.
Purpose of the Study:
- To review evidence on factors influencing DOAC plasma levels.
- To address clinical concerns related to DOAC therapy in AF management.
Main Methods:
- Review of main phase III trial findings.
- Discussion of clinical relevance of factors affecting DOAC plasma levels.
Main Results:
- DOAC dosing, renal impairment, fasting, feeding tubes, and BMI impact DOAC plasma levels.
- Evidence supports addressing these factors for optimal DOAC therapy.
Conclusions:
- Optimizing DOAC therapy requires careful consideration of patient-specific factors.
- The need for specific DOAC antidotes warrants further attention.
