Insights

Cardioversion for atrial fibrillation requires oral anticoagulation to prevent stroke. Non-vitamin K antagonist oral anticoagulants offer advantages over older drugs due to their faster action and predictable effects.

Area of Science:

  • Cardiology
  • Pharmacology

Background:

  • Cardioversion for atrial fibrillation carries a risk of thromboembolic events, particularly ischemic stroke.
  • Oral anticoagulation is essential before and after cardioversion to mitigate this risk.
  • Evaluating stroke risk and arrhythmia onset guides anticoagulation strategy.

Purpose of the Study:

  • To review the role of anticoagulation in cardioversion for atrial fibrillation.
  • To compare vitamin K antagonists (VKAs) with non-VKA oral anticoagulants for this indication.

Main Methods:

  • Literature review and synthesis of current guidelines and evidence.
  • Analysis of anticoagulant properties, efficacy, and safety profiles.

Main Results:

  • Vitamin K antagonists have been the traditional anticoagulants for cardioversion.
  • Non-VKA oral anticoagulants demonstrate a rapid onset of action and predictable effects.
  • Non-VKA oral anticoagulants eliminate the need for routine monitoring.

Conclusions:

  • Non-VKA oral anticoagulants represent a potentially preferred option for anticoagulation during cardioversion.
  • Their predictable pharmacokinetics and pharmacodynamics simplify management and may improve patient outcomes.

Amyloid Fibrils

Amyloid fibrils are aggregates of misfolded proteins.  Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils. 
Amyloid deposits were observed as early as 1639 in the liver and the spleen.   In 1854, Rudolph Virchow performed iodine staining,...

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...

Fibril-associated Collagen01:11

Fibril-associated Collagen

Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated collagens interrupted triple-helices). FACIT help connect and attach the collagen fibrils with each other as well as with other proteins of the extracellular matrix.
For example, the type II collagen fibrils in cartilage have covalently bound type IX fibril-associated collagens at regular intervals. Other types of fibril-associated collagens are...

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...

Gene Therapy00:59

Gene Therapy

Gene therapy is a technique where a gene is inserted into a person’s cells to prevent or treat a serious disease. The added gene may be a healthy version of the gene that is mutated in the patient, or it could be a different gene that inactivates or compensates for the patient’s disease-causing gene. For example, in patients with severe combined immunodeficiency (SCID) due to a mutation in the gene for the enzyme adenosine deaminase, a functioning version of the gene can be...
