Atrial Myopathy Underlying Atrial Fibrillation

Arrhythmia & Electrophysiology Review, 2020
While AF most often occurs in the setting of atrial disease, current assessment and treatment of patients with AF does not focus on the extent of the atrial myopathy that serves as the substrate for this arrhythmia. Atrial myopathy, in particular atrial fibrosis, may initiate a vicious cycle in which atrial myopathy leads to AF, which in turn leads to ...

Atrial fibrillation and electrophysiology in transgenic mice with cardiac-restricted overexpression of FKBP12 [PDF]

, 2019
Cardiomyocyte-restricted overexpression of FK506-binding protein 12 transgenic (αMyHC-FKBP12) mice develop spontaneous atrial fibrillation (AF). The aim of the present study is to explore the mechanisms underlying the occurrence of AF in αMyHC-FKBP12 ...

RHYTHM-AF: design of an international registry on cardioversion of atrial fibrillation and characteristics of participating centers [PDF]

, 2012
BACKGROUND Atrial fibrillation is a serious public health problem posing a considerable burden to not only patients, but the healthcare environment due to high rates of morbidity, mortality, and medical resource utilization. There are limited data on the

Optimising Large Animal Models of Sustained Atrial Fibrillation: Relevance of the Critical Mass Hypothesis

Frontiers in Physiology, 2021
BackgroundLarge animal models play an important role in our understanding of the pathophysiology of atrial fibrillation (AF). Our aim was to determine whether prospectively collected baseline variables could predict the development of sustained AF in ...

Atrial natriuretic factor (ANF) and renin-aldosterone in volume regulation of patients with cirrhosis [PDF]

, 1989
The role of the atrial natriuretic factor and of the main counteracting sodium-retaining principle, the renin-aldosterone system, in acute volume regulation of cirrhosis of the liver has been investigated.

Altered excitation-contraction coupling in human chronic atrial fibrillation [PDF]

, 2012
This review focuses on the (mal)adaptive processes in atrial excitation-contraction coupling occurring in patients with chronic atrial fibrillation. Cellular remodeling includes shortening of the atrial action potential duration and effective refractory ...

Extinction Dynamics of Cardiac Fibrillation [PDF]

, 2018
During episodes of atrial fibrillation, the heart's electrical activity becomes disorganized and shows fragmenting spiral waves. To systematically address how this pattern terminates using spatially extended simulations exceeds current computational ...

Glycemic control is associated with atrial structural remodeling in patients with type 2 diabetes

BMC Cardiovascular Disorders, 2019
Background Diabetes mellitus (DM) has been demonstrated to be a strong risk factor for development and perpetuation of atrial fibrillation (AF). However, how DM and glycemic control affect the pathogenesis of AF has not been sufficiently investigated ...
