Amyloid Fibrils03:03

Amyloid Fibrils

12.0K
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,...

Characteristics and Functions of Blood01:26

Characteristics and Functions of Blood

10.4K
Blood is specialized connective tissue comprising about 8% of the body mass. It has a thick, liquid extracellular matrix that contains cells, dissolved proteins, and electrolytes, making it five times more viscous than water. Blood is warm, around 38°C, and has an alkaline pH ranging from 7.35 to 7.45.
The primary function of blood is to transport oxygen and carbon dioxide between tissues and the lungs. Oxygenated blood is bright red, while oxygen-depleted blood is darker. It also carries...

Fibril-associated Collagen01:11

Fibril-associated Collagen

3.4K
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...

Coronary Circulation01:21

Coronary Circulation

7.4K
The heart, an organ critical to survival, gets nourishment not from the blood it pumps but from a separate circulation system known as coronary circulation. This is the shortest circulation in the body and is responsible for supplying the heart with the nutrients it needs to function effectively.
Coronary circulation begins at the base of the aorta, where two main arteries arise—the left and right coronary arteries. These arteries encircle the heart in the coronary sulcus and supply the...

Fetal Circulation01:14

Fetal Circulation

3.1K
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Summary
This summary is machine-generated.

Radiofrequency ablation (RFA) for atrial fibrillation (AF) and atrial flutter (AFl) impacts blood circulation. Isolated RFA for AF or AFl shows better effectiveness than combined RFA within 3 months post-procedure.

Area of Science:

  • Cardiology
  • Electrophysiology
  • Vascular Medicine

Background:

  • Atrial fibrillation (AF) and atrial flutter (AFl) are common arrhythmias.
  • Radiofrequency ablation (RFA) is a standard treatment for these conditions.
  • Understanding post-procedural hemodynamic changes is crucial for patient management.

Purpose of the Study:

  • To evaluate functional blood circulation parameters in the first 3 months after RFA for AF, AFl, or combined AF/AFl.
  • To compare the effectiveness and hemodynamic impact of isolated versus combined RFA procedures.

Main Methods:

  • 113 patients undergoing RFA for AF, AFl, or combined AF/AFl were studied.
  • Functional parameters including blood pressure (BP), heart rate (HR), electrocardiographic (QTc interval), and echocardiographic indices (RA, RV, EDV, ESV, EF) were assessed.
  • Assessments were performed pre-RFA, acutely post-RFA (3-5 days), and 3 months post-RFA.

Main Results:

  • Arrhythmia recurrence was highest in the combined AF/AFl group acutely and at 3 months.
  • Isolated AF/AFl RFA led to decreased HR, RA/RV size, and increased BP/QTc interval.
  • Combined AF/AFl RFA resulted in decreased ejection fraction (EF) and increased BP, QTc interval, and end-systolic volume (ESV).

Conclusions:

  • The effectiveness of RFA for isolated AF and AFl is superior to combined RFA within 3 months.
  • Both isolated and combined RFA procedures induce significant hemodynamic and electrocardiographic changes.
  • Combined RFA for AF and AFl is associated with a higher recurrence rate and more pronounced negative effects on cardiac function compared to isolated procedures.
