Direct Oral Anticoagulants (DOACs)

Direct Oral Anticoagulants (DOACs) have transformed modern anticoagulation by providing predictable, safe, and convenient alternatives to warfarin for stroke prevention, VTE management, and thromboembolic risk reduction in cardiovascular disease. This session provides a comprehensive exploration of pharmacology, dosing strategies, clinical applications, bleeding risk mitigation, and management of special populations. As clinicians increasingly search for a focused cardiology conference, this session equips participants with a deep understanding of drug selection, monitoring principles, and evidence-based decision-making.

The description highlights the four major DOACs—apixaban, rivaroxaban, dabigatran, and edoxaban—and compares mechanisms involving factor Xa and direct thrombin inhibition. Participants will examine pharmacokinetics, food interactions, renal clearance, drug–drug interactions, and reversal agents such as andexanet alfa and idarucizumab. The session explains how DOACs simplify anticoagulation by eliminating routine INR monitoring, while emphasizing circumstances where monitoring or dose adjustments are necessary.

A major focus is implementing advanced DOAC management strategies in atrial fibrillation, VTE treatment, extended prophylaxis, peri-procedural planning, cardioversion, and structural heart interventions. The session describes dosing nuances based on kidney function, body weight, age, bleeding risk, and concomitant therapies. Participants will learn practical frameworks for managing bleeding emergencies, bridging decisions, and perioperative interruption.

The content also addresses challenging populations—elderly patients, those with CKD, liver disease, malignancy, thrombophilia, and patients requiring dual antiplatelet therapy. Real-world cases explain how to balance ischemic and bleeding risks in AF with coronary stents, post-TAVR patients, and individuals undergoing complex PCI.

Future topics include DOAC use in LV thrombus, emerging agents with extended half-lives, improved reversal therapies, and personalized anticoagulation based on genomics and AI-based risk predictors. By the end of the session, clinicians will feel confident prescribing and managing DOACs in diverse scenarios.

Core Concepts in DOAC Therapy

Mechanisms and Pharmacology

  • Understanding factor Xa vs. direct thrombin inhibition.
  • Reviewing half-life, absorption, and clearance differences.

Clinical Indications and Dosing

  • Selecting DOACs for AF, VTE, and prophylaxis.
  • Adjusting dose according to renal function and age.

Bleeding Management and Reversal

  • Using reversal agents effectively.
  • Managing minor, moderate, and major bleeding.

Peri-Procedural Planning

  • Timing interruption and re-initiation.
  • Balancing thrombosis and bleeding risks.

Benefits to Clinical Practice

Improved Safety Profile
Lower rates of major bleeding vs. warfarin in many settings.

Simplified Management
Predictable dosing reduces need for routine monitoring.

Better Patient Compliance
Oral dosing and fewer restrictions improve adherence.

Enhanced Outcomes
Lower stroke rates and mortality in AF patients.

Reduced Hospital Burden
Fewer complications and monitoring visits required.

 

Broader Application
Effective across diverse cardiovascular indications.
