Insights

Direct oral anticoagulants have transformed atrial fibrillation care. This consensus highlights the need for comprehensive geriatric assessment to guide direct oral anticoagulant prescribing in frail, elderly patients, a high-risk group needing further study.

Area of Science:

  • Geriatrics
  • Cardiology
  • Pharmacology

Background:

  • Direct oral anticoagulants (DOACs) have revolutionized atrial fibrillation (AF) management over the past decade.
  • However, evidence regarding DOAC effectiveness and safety in the oldest and frailest populations with AF remains limited.
  • Frailty, a syndrome of reduced physiological reserves, increases vulnerability and is linked to adverse outcomes in AF patients.

Purpose of the Study:

  • To address the lack of data on DOACs in frail AF patients.
  • To propose integrating comprehensive geriatric assessment (CGA) into clinical practice.
  • To provide guidance for DOAC prescription in this high-risk subgroup.

Main Methods:

  • Multidisciplinary consensus review of existing literature.
  • Discussion on the utility of comprehensive geriatric assessment (CGA).
  • Analysis of frailty as a predictor of adverse outcomes in AF.

Main Results:

  • Significant gap in knowledge exists regarding DOACs in frail AF patients.
  • Frailty is associated with increased risk of adverse events in AF.
  • CGA can provide crucial data for personalized DOAC prescription.

Conclusions:

  • Current evidence is insufficient to guide DOAC use in frail AF patients.
  • Integrating CGA into the clinical evaluation is essential for optimizing DOAC therapy.
  • This approach will help manage the unique risks and needs of this vulnerable population.

Anticoagulant Drugs: Vitamin K Antagonists and Direct Oral Anticoagulants

Oral anticoagulants are vital tools in preventing and treating blood clotting disorders. This diverse class of medications can be categorized as vitamin K antagonists, exemplified by warfarin, and direct thrombin inhibitors (DTIs), such as dabigatran, as well as factor Xa inhibitors, including rivaroxaban.
Warfarin, a prominent vitamin K antagonist family member, exerts its effect by inhibiting the enzyme VKORC1 (vitamin K epoxide reductase complex 1). By hindering this enzyme, warfarin...

Venous Thrombosis III: Interprofessional Care

Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Anticoagulant Drugs: Low-Molecular-Weight Heparins

Hemostasis is a crucial process that prevents excessive blood loss from damaged blood vessels. It involves various mechanisms such as vasoconstriction, platelet adhesion and activation, and fibrin formation. The importance of each mechanism depends on the type of vessel injury. In contrast, thrombosis is the abnormal formation of a blood clot within the blood vessels, leading to potential complications if the clot obstructs blood flow. Thrombosis can be caused by increased coagulability of the...

Antiplatelet Drugs: Prostaglandin Synthesis, P2Y12 and Glycoprotein IIb/IIIa Inhibitors

Antiplatelet drugs emerge as frontline defenders against the insidious threat of thromboembolic diseases, where abnormal clots obstruct vital blood vessels. These drugs stand as bulwarks, inhibiting platelet aggregation and clot formation, thereby mitigating the risk of life-threatening conditions like myocardial infarction, coronary artery disease, and thrombotic strokes.
Prostaglandin synthesis inhibitors, exemplified by the widely known aspirin, wield their power by irreversibly acetylating...
