Insights

Digoxin use in atrial fibrillation patients without heart failure is linked to increased adverse outcomes. In heart failure patients, digoxin should be reserved for those with inadequate rate control or intolerance to other therapies.

Area of Science:

  • Cardiology
  • Pharmacology

Background:

  • Digoxin is a medication historically used for rate control in atrial fibrillation.
  • Recent observational studies have re-evaluated its clinical outcomes.

Purpose of the Study:

  • To review current evidence on digoxin's clinical outcomes in atrial fibrillation.
  • To provide guidance on contemporary digoxin use in this patient population.

Main Methods:

  • Review of recent observational analyses and clinical trial data.
  • Synthesis of evidence regarding digoxin's safety and efficacy.

Main Results:

  • Digoxin use in atrial fibrillation patients without heart failure is associated with increased adverse events.
  • Evidence for increased risk in atrial fibrillation patients with heart failure is inconsistent.
  • Digoxin should generally be avoided in patients without heart failure.

Conclusions:

  • Reserve digoxin for atrial fibrillation patients with heart failure who have inadequate rate control or are intolerant to other treatments.
  • Careful consideration of risks and benefits is crucial for digoxin therapy in atrial fibrillation.

Amyloid Fibrils03:03

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...

Role of Septins01:02

Role of Septins

Septins are the recently discovered fourth major protein component of the cytoskeleton, along with microfilaments, microtubules, and intermediate filaments. These proteins can associate with other cytoskeletal filaments and carry out varied roles or can be free-floating in the cytoplasm.
Cellular Functions of Septins
Recent studies have revealed the multifaceted roles of septins in various cellular processes such as cytokinesis, ciliogenesis, and neurogenesis. Septins act as scaffolds and...

The Role of Culture01:23

The Role of Culture

Culture plays a crucial role in shaping self-identity and influencing thought and behavior, a foundational interest within social psychology. The multicultural perspective recognizes that individuals do not exist in a vacuum; instead, their experiences, perceptions, and actions are deeply influenced by the intersecting dimensions of their cultural, ethnic, and social group affiliations.Cultural Influence on Self-Identity and Social PerceptionCultural frameworks inform how individuals define...
