Management strategies for optimal control of anticoagulation in patients with atrial fibrillation

Area of Science:

• Cardiology
• Pharmacology
• Thrombosis Management

Background:

• Atrial fibrillation necessitates anticoagulant therapy, primarily vitamin K antagonists (VKAs), to prevent thromboembolic events like ischemic stroke.
• Maintaining therapeutic anticoagulation intensity within the target range is challenging, with deviations increasing risks of bleeding and thrombosis.
• Effective management requires frequent monitoring and dose adjustments to optimize patient outcomes.

Purpose of the Study:

• To review management strategies for optimizing vitamin K antagonist therapy in patients with atrial fibrillation.
• To highlight the importance of achieving and maintaining the international normalized ratio within the therapeutic target range.
• To discuss the efficacy and safety of modern anticoagulation management approaches.

Main Methods:

• Review of existing literature on anticoagulation management in atrial fibrillation.
• Analysis of strategies including computer-assisted dosing algorithms and centralized anticoagulation clinics.
• Evaluation of self-testing and self-dosing of international normalized ratio (INR) with VKAs.

Main Results:

• Suboptimal anticoagulation intensity (too low or too high) significantly elevates the risk of adverse events.
• Computer-assisted dosing and centralized care models improve time in therapeutic range (TTR).
• Self-testing and self-dosing of INR have demonstrated effectiveness and safety over the past two decades.

Conclusions:

• Optimizing VKA therapy in atrial fibrillation is critical for preventing thromboembolism and ensuring patient safety.
• Advanced management strategies, including technology-assisted dosing and patient self-management, enhance anticoagulation control.
• Continued research and implementation of these strategies are vital for improving care for patients on VKA therapy.
