Hydrogen Sulfide Ameliorates Angiotensin II-Induced Atrial Fibrosis Progression to Atrial Fibrillation Through Inhibition of the Warburg Effect and Endoplasmic Reticulum Stress

Frontiers in Pharmacology, 2021
Atrial fibrosis is the basis for the occurrence and development of atrial fibrillation (AF) and is closely related to the Warburg effect, endoplasmic reticulum stress (ERS) and mitochondrion dysfunctions-induced cardiomyocyte apoptosis. Hydrogen sulfide (

Механизмы, клиническая значимость и взаимоотношение тканевого фиброза и фибрилляции предсердий = Mechanisms, clinical significance and relationship of tissue fibrosis and atrial fibrillation = Механізми, клінічна значущість та взаємовідношення тканинного фіброзу і фібриляції передсердь

Journal of Education, Health and Sport, 2017
Atrial fibrillation (AF) is the most common heart rhythm disorder in clinical practice. Today proved that traditional pharmacologic therapies are effective in patients with paroxysmal atrial fibrillation with no structural disorders of the myocardium ...

Visualization of intensive atrial inflammation and fibrosis after cryoballoon ablation: PET/MRI and LGE‐MRI analysis

Journal of Arrhythmia, 2021
Background Atrial inflammation plays an important role in initiating atrial fibrosis, which could perpetuate atrial fibrillation (AF). However, the method of visualization of atrial inflammation has not been established.

The Dose-Dependent Effects of Spironolactone on TGF-β1 Expression and the Vulnerability to Atrial Fibrillation in Spontaneously Hypertensive Rats

Cardiology Research and Practice, 2021
Objective. This study tends to assess the dose-dependent effects of spironolactone on TGF-β1 expression, atrial fibrosis, and the vulnerability to atrial fibrillation in spontaneously hypertensive rats (SHRs) and tries to clarify the association of ...

Infrasound exposure promotes development of atrial fibrosis in rats

Annals of Medicine, 2021
Introduction Recent data has shown a significant association between noise exposure and atrial fibrillation (AF) in a large cohort [1] but the pathophysiology remains unclear.

Fibrosis and Atrial Fibrillation

JACC: Clinical Electrophysiology, 2017
![Figure][1] In the search for better understanding of atrial fibrillation (AF) mechanisms and the evolution of clinical manifestations of the disease, much recent effort has focused on the role of atrial fibrosis.

Cfa-circ002203 was upregulated in rapidly paced atria of dogs and involved in the mechanisms of atrial fibrosis

Frontiers in Cardiovascular Medicine, 2023
Background and aimsThe role of circular RNAs (circRNAs) in the pathophysiology of cardiovascular disease is gradually being elucidated; however, their roles in atrial fibrillation (AF)-related fibrosis are largely unknown.

New therapeutic target for the non-electrophysiological signaling in atrial fibrosis and fibrillation such as inflammation

Journal of Arrhythmia, 2012
We have experimentally established appropriate models of atrial fibrillation (AF) with atrial interstitial fibrosis. Two approaches were adopted. Firstly, left atrial fibrosis was induced by continuous infusion of angiotensin II (AII).

How to detect atrial fibrosis.

Journal of geriatric cardiology : JGC, 2017
In the last twenty years, new imaging techniques to assess atrial function and to predict the risk of recurrence of atrial fibrillation after treatment have been developed. The present review deals with the role of these techniques in the detection of structural and functional changes of the atrium and diagnosis of atrial remodeling, particularly ...

Cardiac fibrosis and atrial fibrillation

Postępy Higieny i Medycyny Doświadczalnej, 2022
Abstract Cardiac fibrosis is characterized by the imbalance of production and degradation of the extracellular matrix. The result of this process is an accumulation of scar tissue, which is associated with many pathological processes such as excessive mechanical stress on the heart, inflammation, ischemia, oxidative stress, or ...
