Detection of fibrotic remodeling of epicardial adipose tissue in patients with atrial fibrillation: Imaging approach based on histological observation

Heart Rhythm O2, 2021
Background: Fibrotic remodeling of epicardial adipose tissue (EAT) is crucial for proinflammatory atrial myocardial fibrosis, which leads to atrial fibrillation (AF).

Association between interatrial septum adiposity and atrial fibrillation: transesophageal echocardiography imaging and autopsy study

Scientific Reports, 2023
Recent clinical evidence has suggested that interatrial septal (IAS) adiposity contributes to atrial fibrillation (AF). The present study aimed to confirm the usefulness of transesophageal echocardiography (TEE) to estimate IAS adiposity in patients with

Predictors of outcome after catheter ablation for atrial fibrillation: Group analysis categorized by age and type of atrial fibrillation

Annals of Noninvasive Electrocardiology, 2023
Background The outcome of catheter ablation could probably differ among patients with atrial fibrillation (AF), depending on age and AF type. We aimed to investigate the difference in predictors of outcome after catheter ablation for AF among the patient

Interatrial conduction time is associated with left atrial low voltage area and predicts the recurrence after single atrial fibrillation ablation

Journal of Arrhythmia, 2023
Background Interatrial conduction time (IACT) prolongs in fibrotic left atrium. We tested the hypothesis that IACT is related to left atrial low voltage area (LVA) and predicts the recurrence after single atrial fibrillation (AF) ablation.

Distinctively different predictors for long‐term outcomes between responders and nonresponders who underwent cardiac resynchronization therapy

Journal of Arrhythmia, 2021
Background It is common to develop heart failure (HF) events even in respondents to cardiac resynchronization therapy (CRT) during a long‐term observation period.

Development of a gene doping detection method to detect overexpressed human follistatin using an adenovirus vector in mice [PDF]

PeerJ, 2021
Background Gene doping is the misuse of genome editing and gene therapy technologies for the purpose of manipulating specific genes or gene functions in order to improve athletic performance. However, a non-invasive detection method for gene doping using

Fragmented QRS as a risk marker for the occurrence of ventricular fibrillation in patients with variant angina

Annals of Noninvasive Electrocardiology, 2022
Background Variant angina (VA) is caused by reversible coronary artery spasm, which is characterized by chest pain with ST‐segment elevations on standard 12‐lead electrocardiogram (ECG) at rest. Ventricular fibrillation (VF) is often caused by VA attack,

Role of fragmented QRS and Shanghai score system in recurrence of ventricular fibrillation in patients with early repolarization syndrome

Annals of Noninvasive Electrocardiology, 2021
Background The Shanghai Score System, which weighs electrocardiogram (ECG) findings reflecting repolarization abnormalities, has been proposed for diagnosis of early repolarization syndrome (ERS). However, recent studies have suggested the involvement of
