Box Isolation of fibrotic areas: A substrate modification approach in atrial fibrillation patients

Revista Portuguesa de Cardiologia, 2017
In the last years, atrial fibrosis was shown to be an independent predictor of procedural failure in patients with paroxysmal and persistent atrial fibrillation.

Commonalities of platelet dysfunction in heart failure with preserved ejection fraction and underlying comorbidities

ESC Heart Failure, Volume 12, Issue 2, Page 1013-1028, April 2025.
Abstract Heart failure with preserved ejection fraction (HFpEF) is characterized by a lack of a specific targeted treatment and a complex, partially unexplored pathophysiology. Common comorbidities associated with HFpEF are hypertension, atrial fibrillation, obesity and diabetes.

Recurrence of atrial fibrillation and late cardiovascular events in patients with persistent atrial fibrillation after restoration of sinus rhythm

, 2020
The aim – to study the role of late recurrences of AF in predicting adverse course of the disease in patients with persistent AF after cardioversion at 9-month follow-up. Material and methods. The study included 120 patients with documented persistent

Stability of Conduction Patterns in Persistent Atrial Fibrillation

Computing in Cardiology Conference (CinC), 2017
There is a growing interest and practice of guidance of catheter ablation of atrial fibrillation (AF) by specific conduction patterns (rotors, point sources, regions of conduction slowing). Temporal stability of conduction patterns in AF has not been studied in detail.

The G protein-gated potassium current I(K,ACh) is constitutively active in patients with chronic atrial fibrillation

, 2005
Background— The molecular mechanism of increased background inward rectifier current (IK1) in atrial fibrillation (AF) is not fully understood. We tested whether constitutively active acetylcholine (ACh)-activated IK,ACh contributes to enhanced basal ...

Pathophysiology of Paroxysmal and Persistent Atrial Fibrillation: Rotors, Foci and Fibrosis

, 2017
Recent advances in our understanding of the mechanisms underlying atrial fibrillation (AF) have further underscored the complex pathophysiological basis of the arrhythmia.

Duration of Persistent Atrial Fibrillation Is Associated with Alterations in Human Gut Microbiota and Metabolic Phenotypes

mSystems, 2019
Atrial fibrillation (AF) has been shown to be associated with disordered gut microbiota (GM). The underlying factors governing persistent AF (psAF) are not well understood, and the association between AF duration and GM profiles remains to be ...

The effects of sodium–glucose cotransporter 2 inhibitors on the ‘forgotten’ right ventricle

ESC Heart Failure, Volume 12, Issue 2, Page 1045-1058, April 2025.
Abstract With the progress in diagnosis, treatment and imaging techniques, there is a growing recognition that impaired right ventricular (RV) function profoundly affects the prognosis of patients with heart failure (HF), irrespective of their left ventricular ejection fraction (LVEF).
