INTRODUCTION: Atrial fibrillation (AF) has been proposed as a risk factor for cognitive impairment, even in the absence of a history of stroke. This study investigates whether AF is associated with increased risk of cognitive decline in a community-dwelling population of adults over the age of 50. METHODS: Data from the 1st and 3rd waves of The Irish Longitudinal Study on Ageing (TILDA) were used (4-year follow-up period). TILDA is a large prospective cohort study of community-dwelling adults over the age of 50 in Ireland...

BACKGROUND: The time-to-isolation (TTI) may be a physiological predictor of durable isolations, and TTI-guided dosing strategies are widely performed in cryoballoon ablation. We sought to investigate the impact of the order of targeting the pulmonary veins (PVs) on the TTI values of left ipsilateral PVs. METHODS: This study included 144 atrial fibrillation patients who underwent PV isolations using 28-mm fourth-generation cryoballoons. In 101 patients, the left superior PV (LSPV) was targeted and followed by the left inferior PV (LIPV) (group 1), and the LIPV was targeted and followed by the LSPV in the remaining 43 (group 2)...

PURPOSE: After antral pulmonary vein isolation (PVI), electrical potentials may persist deep in the right superior pulmonary vein (RSPV). Whether these potentials signify true pulmonary vein potential (PVP) (implying inadequate RSPV isolation) or are far-field potentials (FFP) from the superior vena cava (SVC) is unclear. Here, we attempt to assess the incidence of persistent potentials in RSPV post-isolation and methods to differentiate PVP from FFP. METHODS: Following PVI, we mapped the RSPV and the SVC with simultaneously placed catheters...

Primary and Secondary Stroke Prevention: Physical Activity Abstract. The evidence of positive effects of physical activity in primary and secondary stroke prevention has steadily increased in the last years. It is established that physical activity on a regular basis has a positive influence on the majority of vascular risk factors (e. g. on obesity, arterial hypertension, atrial fibrillation and so on). After a stroke, one of the main challenges is reducing the risk of a recurrent event and its possible consequences...

Atrial fibrillation and ischaemic stroke: current treatment and personalized risk prediction of intracerebral haemorrhage Abstract. Atrial fibrillation is a major cause of stroke. Management of patients with atrial fibrillation and stroke is challenging. In this review article, based on the most recent scientific literature, the following questions are discussed: 1) When is the optimal point in time to start anticoagulation after a recent stroke? 2) How to treat patients with atrial fibrillation that have a stroke despite anticoagulant therapy? 3) What is the added value of MRI for personalized risk-prediction of intracerebral hemorrhage? 4) How to treat patients with atrial fibrillation after intracerebral hemorrhage? We provide recommendations for daily clinical management...

Recurrence rates of atrial fibrillation (AF) after pulmonary vein isolation (PVI) are higher in patients with a left atrial low-voltage area (LVA) than those without. However, the efficacy of LVA guided ablation is still unknown. The purpose of this study-the Efficacy and Safety of Left Atrial Low-voltage Area Guided Ablation for Recurrence Prevention Compared to Pulmonary Vein Isolation Alone in Patients with Persistent Atrial Fibrillation trial (SUPPRESS-AF trial)-is to elucidate whether LVA guided ablation in addition to PVI is superior to PVI alone in patients with persistent AF...

BACKGROUND: Antiarrhythmic drugs are often used in the management of patients with atrial fibrillation (AF). Sotalol is conventionally initiated in the inpatient setting for monitoring efficacy and adverse effects, including QTc interval prolongation and torsades de pointes (TdP) proarrhythmia. OBJECTIVE: We aimed to evaluate the efficacy and safety of outpatient initiation of sotalol for the treatment of AF in a select group of patients with cardiac implantable electronic devices (CIEDs): permanent pacemakers (PPMs), implantable cardioverter defibrillators (ICDs), and implantable loop recorders (ILRs) capable of continuous rhythm monitoring remotely...

BACKGROUND: The tryptophan-kynurenine pathway is linked to inflammation. We hypothesize that metabolites implicated in this pathway may be associated with the risk of heart failure (HF) or atrial fibrillation (AF) in a population at high risk of cardiovascular disease. OBJECTIVES: We aimed to prospectively analyze the associations of kynurenine-related metabolites with the risk of HF and AF and to analyze a potential effect modification by the randomized interventions of the PREDIMED (Prevención con Dieta Mediterránea) trial with Mediterranean diet (MedDiet)...

In patients with atrial fibrillation, intracardiac electrogram signal amplitude is known to decrease with increased structural tissue remodeling, referred to as fibrosis. In addition to the isolation of the pulmonary veins, fibrotic sites are considered a suitable target for catheter ablation. However, it remains an open challenge to find fibrotic areas and to differentiate their density and transmurality. This study aims to identify the volume fraction and transmurality of fibrosis in the atrial substrate...

In recent years, with the development of artificial intelligence, deep learning model has achieved initial success in ECG data analysis, especially the detection of atrial fibrillation. In order to solve the problems of ignoring the correlation between contexts and gradient dispersion in traditional deep convolution neural network model, the hybrid attention-based deep learning network (HADLN) method is proposed to implement arrhythmia classification. The HADLN can make full use of the advantages of residual network (ResNet) and bidirectional long-short-term memory (Bi-LSTM) architecture to obtain fusion features containing local and global information and improve the interpretability of the model through the attention mechanism...

Purpose: Malnutrition has been shown to be related to adverse clinical outcomes in patients with heart failure, hypertension, atrial fibrillation and other cardiovascular diseases. However, in the patients with coronary artery disease (CAD) undergoing percutaneous coronary interventions (PCI), especially in the elderly, the association of nutritional state and all-cause mortality remains unknown. We aimed to investigate the association of malnutrition with all-cause mortality in the elder patients undergoing PCI...

The genetic causes of atrial fibrillation (AF) with slow conduction are unknown. Eight kindreds with familial AF and slow conduction, including a family affected by early onset AF, heart block and incompletely penetrant non-ischemic dilated cardiomyopathy (DCM) underwent whole exome sequencing. A known pathogenic mutation in the desmin (DES) gene resulting in p.S13F substitution (NM_001927.3:c.38C>T) at a PKC phosphorylation site was identified in all four members of the kindred with early-onset AF and heart block, while only two developed DCM...

INTRODUCTION: In May 2020, a novel cryoballoon system (POLARx; Boston Scientific) became available for catheter ablation of atrial fibrillation (AF). The design of the cryoballoon is comparable to the Arctic Front Advance Pro (AFA-Pro; Medtronic), but it is more compliant during freezing. We compared the procedural efficacy, biophysical parameters, and risk of phrenic nerve palsy (PNP) between the two cryoballoons. METHODS: Embase, MEDLINE, Web of Science, Cochrane, and Google Scholar databases were searched until June 1, 2021 for relevant studies comparing POLARx versus AFA-Pro in patients undergoing pulmonary vein isolation (PVI) for AF...
