Lifestyle modification in atrial fibrillation: Mechanisms, phenotypes and ablation outcomes

Experimental Physiology, EarlyView.
Abstract Atrial fibrillation (AF) is the most prevalent sustained cardiac arrhythmia and is associated with significant morbidity, mortality and healthcare utilization. Catheter ablation is increasingly used as a rhythm‐control intervention for patients with symptomatic paroxysmal and persistent AF, yet recurrence rates remain suboptimal.

A new approach to an old disease: Ageing, arrhythmogenic substrate and the role of risk‐factor modification in atrial fibrillation

Experimental Physiology, EarlyView.
Abstract Atrial fibrillation (AF) prevalence rises sharply with age due to two independent mechanisms. Ageing produces irreversible arrhythmogenic substrate changes through progressive fibrosis, cellular senescence and mitochondrial dysfunction, while modifiable risk factors such as obesity, hypertension, sleep apnoea, diabetes and alcohol use promote ...

Bifunctional agents for reperfusion arrhythmias: Novel hybrid vitamin E/class I antiarrhythmics

, 2003
We have synthesized a series of hybrid compounds combining the pharmacophoric redox moieties of vitamin E and key features responsible for the antiarrhythmic properties of the class I antiarrhythmics procainamide and lidocaine. Procainamide analogue (2a)

Therapy for patient with atrial fibrillation: in search of a balance between efficacy and safety

Клинический разбор в общей медицине
This paper analyzes aspects of the efficacy and safety of antiarrhythmic drugs in the treatment of atrial fibrillation. It considers drug-drug interactions of antiarrhythmics with other drugs, especially in the near circle, i.e.

TMEM16A Ca2+‐activated Cl− channel: Functional interactions with cytoskeletal and membrane‐associated proteins

The Journal of Physiology, EarlyView.
Abstract figure legend The calcium‐activated chloride (ClCa) channel TMEM16A (also known as ANO1) plays critical roles in ion transport, neurotransmission and smooth muscle contraction. Dysregulation of TMEM16A channel activity contributes to the development and progression of various diseases.

Computational modelling of cardiac fibroblast signalling reveals a key role for Ca2+ in driving atrial fibrillation‐associated fibrosis

The Journal of Physiology, EarlyView.
Abstract figure legend A pre‐existing fibroblast signalling model was enhanced by integrating atrial‐specific components and reactions linked to atrial fibrosis and atrial fibrillation (AF). The analysis highlights the central role of Ca2⁺ signalling in driving profibrotic responses to AF‐relevant stimuli, angiotensin‐II and transforming growth factor ...

Mechanistic insights into sex differences in atrial electrophysiology and arrhythmia vulnerability through sex‐specific computational models

The Journal of Physiology, EarlyView.
Abstract figure legend Sex‐specific models of the human atrial myocyte in normal sinus rhythm (nSR) and chronic atrial fibrillation (cAF) revealed increased alternans susceptibility in cAF males and DADs in females, driven primarily by ICaL and ryanodine receptor remodelling.

Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes

The Journal of Physiology, EarlyView.
Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.

PULSE PRESSURE CLASSES AND DOSAGE OF THE MAIN GROUPS OF CARDIAC MEDICATIONS IN PATIENTS AT THE ANNUAL FOLLOW-UP PERIOD AFTER PACING

Journal of V. N. Karazin Kharkiv National University: Series Medicine, 2017
Dose factor of the main groups of cardiac medications in five pulse pressure (PP) classes was studied in 220 patients (110 men and 110 women) at the annual stage after pacing, the average age 70 ± 9 years.
