Influence of cardiac tissue anisotropy on re-entrant activation in computational models of ventricular fibrillation

open access: yes, 2009
The aim of this study was to establish the role played by anisotropic diffusion in (i) the number of filaments and epicardial phase singularities that sustain ventricular fibrillation in the heart, (ii) the lifetimes of filaments and phase singularities,

Association of COPD with adverse outcomes in heart failure patients with preserved ejection fraction

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 799-808, April 2025.
Abstract We performed a systematic review and meta‐analysis to detect the impact of chronic obstructive pulmonary disease (COPD) on the prognosis of heart failure patients with preserved ejection fraction (HFpEF). We systematically screened eligible literature from three electronic databases, PubMed, EMBASE and Cochrane Library, up to April 2023.

IVABRADINE OUTSIDE THE CLINICAL GUIDELINES: INTEREST OF A PRACTITIONER

open access: yesРоссийский кардиологический журнал, 2018
The article is focused on the data concerning the influence of ivabradine on myocardial electrophysiology in experimental and clinical studies. It is shown that ivabradine decreases ventricular rate in chronic atrial fibrillation, and prevents the ...

Gut microbiota‐related modulation of immune mechanisms in post‐infarction remodelling and heart failure

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 942-954, April 2025.
Abstract The immune system has long been recognized as a key driver in the progression of heart failure (HF). However, clinical trials targeting immune effectors have consistently failed to improve patient outcome across different HF aetiologies. The activation of the immune system in HF is complex, involving a broad network of pro‐inflammatory and ...

MELD score predicts outcomes in patients with advanced heart failure: A longitudinal evaluation

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 839-847, April 2025.
Abstract Aims Advanced heart failure (AHF) is characterized by recurrent episodes of haemodynamic instability and frequent hospitalizations, leading to a progressive decline in quality of life and high mortality rates. The objectives of this study were to evaluate the effect of the model for end‐stage liver disease (MELD) score and its variations in ...

Automatic Mode Switching in Atrial Fibrillation [PDF]

open access: yes, 2005
Automatic mode switching (AMS) algorithms were designed to prevent tracking of atrial tachyarrhythmias (ATA) or other rapidly occurring signals sensed by atrial channels, thereby reducing the adverse hemodynamic and symptomatic consequences of a rapid ...

Chronic beta-adrenoceptor blockade and human atrial cell electrophysiology: evidence of pharmacological remodelling [PDF]

open access: yes, 2003
<b>Objective:</b> Chronic beta-adrenoceptor antagonist (β-blocker) treatment reduces the incidence of reversion to AF in patients, possibly via an adaptive myocardial response.
