Insights

Atrial fibrillation (AF) is common in the elderly. Anticoagulant therapy, especially newer non-vitamin K antagonists, improves survival despite bleeding risks, requiring individualized care for older patients.

Area of Science:

  • Cardiology
  • Geriatrics
  • Pharmacology

Background:

  • Atrial fibrillation (AF) is the most prevalent arrhythmia in the elderly.
  • Age is a key factor in AF pathogenesis, and conduction disturbances may precede its onset.
  • Antithrombotic therapy is crucial for improving survival in diagnosed AF patients.

Purpose of the Study:

  • To review the role of antithrombotic therapy in elderly patients with atrial fibrillation.
  • To discuss the benefits and risks of anticoagulation in this population.
  • To highlight the advantages of non-vitamin K antagonist oral anticoagulants (NOACs) and the importance of individualized treatment.

Main Methods:

  • Literature review focusing on atrial fibrillation, aging, antithrombotic therapy, and anticoagulants.
  • Analysis of risk factors, benefits, and adverse events associated with anticoagulation in the elderly.
  • Evaluation of non-vitamin K antagonist oral anticoagulants (NOACs) compared to vitamin K antagonists (VKAs).

Main Results:

  • Elderly patients with AF face increased risks of thromboembolic events and bleeding.
  • Anticoagulant therapy benefits generally outweigh bleeding risks, even in very elderly individuals.
  • Non-vitamin K antagonist oral anticoagulants (NOACs) demonstrate improved efficacy and safety profiles with fewer adverse events compared to VKAs.

Conclusions:

  • Anticoagulant therapy is essential for elderly AF patients to improve survival.
  • Elderly AF patients are frequently undertreated, necessitating a proactive approach.
  • Individualized treatment considering frailty, comorbidities, and polypharmacy is vital for optimizing care, with NOACs offering a favorable option.

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,...

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...

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias

Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...

Structural Protein Function01:56

Structural Protein Function

Structural proteins are a category of proteins responsible for functions ranging from cell shape and movement to providing support to major structures such as bones, cartilage, hair, and muscles. This group includes proteins such as collagen, actin, myosin, and keratin.
Collagen, the most abundant protein in mammals, is found throughout the body. In connective tissue, such as skin, ligaments, and tendons, it provides tensile strength and elasticity.  In bones and teeth, it mineralizes to...

Globular and Fibrous Proteins

Many proteins can be classified into two distinct subtypes - globular or fibrous. These two types differ in their shapes and solubilities.
Globular proteins are also known as spheroproteins and typically are approximately round in shape. They contain a mix of amino acid types and contain differing sequences in their primary structures. Globular proteins have many different functions, such as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be...
