Anticoagulation Course

Lesson 1 • Natural Anticoagulant Mechanisms

Describes endogenous inhibitors that prevent excessive clotting. Understanding these mechanisms contextualizes how therapeutic anticoagulants mimic or augment natural control.

Lesson 2 • Coagulation Cascade Pathways

Examines intrinsic, extrinsic, and common pathways in detail. Clarifies how each factor interacts, enabling precise identification of anticoagulant drug targets.

Lesson 3 • Hemostasis: Primary and Secondary Phases

Covers platelet plug formation and the coagulation cascade sequence. Provides the mechanistic baseline needed for understanding all anticoagulant drug targets.

Lesson 1 • Parenteral Direct Thrombin Inhibitors

Examines bivalirudin, argatroban, and related agents used in specialized clinical settings. Connects these agents to indications where heparin is contraindicated.

Lesson 2 • Heparins: Unfractionated and Low Molecular Weight

Covers antithrombin-mediated inhibition by heparin types and their pharmacokinetic differences. Establishes the basis for monitoring and dosing distinctions covered later.

Lesson 3 • Vitamin K Antagonists

Explains inhibition of vitamin K-dependent clotting factor synthesis and the delayed onset of effect. Prepares learners for INR monitoring and dose management.

Lesson 4 • Antiplatelet Agents in Context

Distinguishes antiplatelet drugs from anticoagulants and explains when each is preferred. Prevents common clinical confusion between the two drug categories.

Lesson 1 • Drug-Drug and Drug-Food Interactions

Catalogs clinically significant interactions affecting anticoagulant efficacy and safety. Directly supports safe prescribing and patient counseling skills.

Lesson 2 • Pharmacodynamic Variability

Addresses patient-specific factors that alter drug response beyond pharmacokinetics. Prepares learners to individualize therapy for high-risk populations.

Lesson 3 • Absorption, Distribution, and Bioavailability

Compares oral versus parenteral bioavailability across anticoagulant classes. Establishes why route of administration affects onset and predictability of effect.

Lesson 1 • Viscoelastic and Point-of-Care Testing

Introduces thromboelastography and rotational thromboelastometry for real-time clot assessment. Connects these tools to perioperative and critical care monitoring.

Lesson 2 • Monitoring DOACs in Special Situations

Addresses scenarios where DOAC quantification is clinically necessary despite routine monitoring not being required. Prepares learners for emergencies and perioperative decisions.

Lesson 3 • Standard Coagulation Assays

Covers PT, INR, aPTT, and thrombin time and their clinical utility. Establishes the monitoring framework applied throughout the course.

Lesson 1 • VTE Prophylaxis in High-Risk Settings

Addresses pharmacological and mechanical prophylaxis in surgical and medical patients. Connects risk stratification tools to prophylaxis intensity selection.

Lesson 2 • Venous Thromboembolism Treatment

Covers acute DVT and PE management, including initial and long-term anticoagulation strategies. Establishes duration and intensity decisions based on clot burden and risk.

Lesson 3 • Anticoagulation in Acute Coronary Syndromes

Covers parenteral anticoagulation during ACS and PCI procedures. Distinguishes anticoagulant roles from antiplatelet roles in acute ischemic events.

Lesson 4 • Atrial Fibrillation Stroke Prevention

Applies stroke risk scoring to anticoagulant selection in atrial fibrillation. Balances thromboembolic risk against bleeding risk for individualized therapy.

Lesson 1 • Heparin Dosing Protocols

Covers weight-based UFH nomograms and LMWH fixed dosing for treatment and prophylaxis. Establishes the dose-response relationship monitored by aPTT and anti-Xa.

Lesson 2 • Transitioning Between Anticoagulants

Provides structured protocols for switching between parenteral and oral agents safely. Minimizes gaps in anticoagulation and avoids supratherapeutic overlap.

Lesson 3 • Warfarin Initiation and Stabilization

Guides loading dose selection, INR monitoring frequency, and dose adjustment algorithms. Prepares learners to achieve stable therapeutic INR efficiently.

Lesson 1 • Supportive Measures and Adjuncts

Addresses transfusion, antifibrinolytics, and procedural hemostasis as adjuncts to reversal. Ensures learners integrate pharmacological and non-pharmacological bleeding management.

Lesson 2 • DOAC-Specific Reversal Agents

Covers idarucizumab for dabigatran and andexanet alfa for factor Xa inhibitors. Addresses availability, cost, and clinical decision thresholds for reversal agent use.

Lesson 3 • Reversal of Heparin and LMWH

Covers protamine sulfate dosing for UFH and partial LMWH reversal. Addresses timing, dose calculation, and protamine adverse effects.

Lesson 4 • Warfarin Reversal Approaches

Compares vitamin K, fresh frozen plasma, and four-factor PCC for warfarin reversal. Matches reversal strategy to bleeding urgency and INR elevation.

Lesson 1 • Anticoagulation in Cancer Patients

Addresses cancer-associated thrombosis, LMWH versus DOAC selection, and bleeding risk in thrombocytopenic patients. Covers dose modification with low platelet counts.

Lesson 2 • Anticoagulation During Pregnancy

Covers LMWH as the preferred agent and contraindications to warfarin and DOACs in pregnancy. Addresses VTE treatment, prophylaxis, and peripartum management.

Lesson 3 • Perioperative Anticoagulation Management

Provides structured protocols for interrupting and resuming anticoagulation around procedures. Balances thrombotic and bleeding risk using validated decision frameworks.

Lesson 4 • Heparin-Induced Thrombocytopenia

Explains HIT pathophysiology, 4T score application, and mandatory heparin cessation. Guides selection and dosing of alternative anticoagulants in HIT.
