Atrial fibrillation (AF) is the most common arrhythmia. The most common diagnostic method, 12-lead electrocardiogram (ECG), can record episodes of arrhythmia from which the type and severity can be determined. The Heart Spectrum Blood Pressure Monitor (P2; OSTAR Meditech Corp., New Taipei City, Taiwan) is used to measure cardiovascular pressure change with fast Fourier transform (FFT) analysis to obtain heart rate frequency variability and accurate blood pressure data. We compared the diagnostic efficacy of...
There are a paucity of data on the association of duration of hypertension and blood pressure (BP) level with risk of ischaemic stroke in patients with atrial fibrillation (AF). Our objective was to investigate the association between duration of hypertension and secondly, BP levels with risk of ischaemic stroke among patients with AF.
This article provides new insight on landiolol, an ultra-short acting injectable betablocker, recently approved in Europe, with regard to its pharmacokinetic and pharmacodynamic profile, along with its first experience in Caucasian healthy volunteers and patients with atrial fibrillation. Landiolol as iv formulation exhibited in an emergency setting rapid rate reduction in patients with tachycardic atrial fibrillation without pronounced blood pressure drop both in caucasian and asian populations in similar ...
Deficiency of testosterone was associated with the susceptibility of atrial fibrillation. Angiotensin-II receptor antagonists were shown to reduce atrial fibrillation by improving atrial electrical remodeling. This study investigated the effects and mechanism of valsartan, an angiotensin-II receptor antagonist, on the susceptibility to atrial fibrillation with testosterone deficiency.
P-selectin - a biomarker of platelet and endothelial cell activation is elevated in patients with non-valvular atrial fibrillation (NVAF). However, the association between sP-selectin level and thromboembolic complications in NVAF patients remains controversial. We tested the hypothesis that plasma soluble P-selectin (sPSL) level correlates with the measures of left atrial blood stasis in NVAF.
Radiofrequency ablation has become a safe and effective treatment for atrial fibrillation. We believe that referral to an electrophysiologist for consideration of ablation may allow for better rhythm control and outcomes by altering the natural history of atrial fibrillation progression.
Pre-interventional assessment of atrial wall thickness (AWT) and of subject-specific variations in the anatomy of the pulmonary veins may affect the success rate of RF ablation procedures for the treatment of atrial fibrillation (AF). This study introduces a novel non-contrast enhanced 3D whole-heart sequence providing simultaneous information on the cardiac anatomy-including both the arterial and the venous system-(bright-blood volume) and AWT (black-blood volume).
The aim of this study was to evaluate a spatial correlation between active atrial fibrillation (AF) drivers measured by ECGI and complex fractionated atrial electrograms (CFAEs) in patients with persistent AF.
Beta-blockers are a potential option to manage peri-operative atrial fibrillation. Landiolol is a new ultra-short beta-blocker with a half-life of only 4 minutes and very high beta-1 selectivity which has been used for treatment and prevention of atrial fibrillation in pulmonary surgery and gastro-intestinal surgery. Due to its limited negative inotropic effect and high beta-1 selectivity landiolol allows for control of heart rate with minimal impact on blood pressure. Landiolol is well tolerated by the res...
Recently, the analysis of the spatio-temporal behavior of atrial fibrillation activation patterns has been widely investigated with the aim to better understand the arrhythmia implications on the heart electrical activity. Most of the proposed techniques are based on atrial activation timing detections. Unfortunately atrial activation timings are not easily recognizable on the electrograms (EGMs) and an approach to support the validation of such techniques is highly desirable. The aim of this study is to pr...
Understanding the anatomy, physiology, and arrhythmogenic and thrombogenic roles of the left atrial appendage (LAA) has become very important. The potential deleterious effects of this chamber in patients with atrial fibrillation have led to the development of specific treatments for this structure. It has been established that the LAA is the area where the vast majority of thrombi in nonvalvular atrial fibrillation are formed and that some LAA morphologies may actually facilitate thrombi formation and risk...
Atrial fibrillation frequently develops in patients with sepsis and is associated with increased morbidity and mortality. Unfortunately, risk factors for new-onset atrial fibrillation in sepsis have not been clearly elucidated. Clarification of the risk factors for atrial fibrillation during sepsis may improve our understanding of the mechanisms of arrhythmia development and help guide clinical practice.
High monocyte counts are related to adverse outcomes in cardiovascular disease. Their role in prognostication in patients with atrial fibrillation (AF) is unknown. We investigated whether monocyte counts are useful as a marker of prognosis in patients with AF.
Atrial fibrillation increases the risk of stroke by a factor of 4- to 5-fold, and dementia is a common consequence of stroke. However, atrial fibrillation has been associated with cognitive impairment and dementia, even in patients without prior overt stroke. Non-ischemic mechanisms include cerebral hypoperfusion, vascular inflammation, brain atrophy, genetic factors, and shared risk factors such as age or hypertension. Critical appraisal of studies evaluating the association between atrial fibrillation and...
Stroke is the most feared complication of atrial fibrillation. To prevent stroke, left atrial appendage exclusion has been targeted, as it is the prevalent site for formation of heart thrombi during atrial fibrillation. We review the historic development of methods for exclusion of the left atrial appendage and the evidence to support its amputation during routine cardiac surgery.
Integrated care for the clinical management of atrial fibrillation patients is advocated as a holistic way to improve outcomes; the simple ABC (Atrial fibrillation Better Care) pathway has been proposed. The ABC pathway streamlines care as follows: 'A' Avoid stroke; 'B' Better symptom management; 'C' Cardiovascular and Comorbidity optimisation.
Obstructive sleep apnea (OSA) has been recognized as an independent risk factor for the development and progression of atrial fibrillation (AF). We aimed to investigate the changes in heart rate and atrial and ventricular ectopy after continuous positive airway pressure (CPAP) treatment in patients with OSA and AF.
Long-term monitoring has been advocated to enhance the detection of atrial fibrillation (AF) in patients with stroke.
Oral anticoagulants reduce the risk of stroke in patients with atrial fibrillation. However, many patients with atrial fibrillation at elevated stroke risk are not treated with oral anticoagulants.
Tricuspid regurgitation pressure gradient (TRPG) is reportedly a predictor of cardiovascular (CV) mortality in patients without atrial fibrillation (AF); its relationship with cardiac outcomes in patients with AF has never been evaluated. This study aimed to examine the ability of TRPG to predict CV events and all-cause mortality in patients with AF.
The most efficient first-time invasive treatment, for achieving sinus rhythm, in symptomatic paroxysmal atrial fibrillation has not been established. We aimed to compare percutaneous catheter and video-assisted thoracoscopic pulmonary vein radiofrequency ablation in patients referred for first-time invasive treatment due to symptomatic paroxysmal atrial fibrillation. The primary outcome of interest was the prevalence of atrial fibrillation with and without anti-arrhythmic drugs at 12 months.
Fibrotic remodeling of the atria plays a key role in the pathogenesis of atrial fibrillation (AF). As little is known about the contribution of circulating monocytes in atrial remodeling and the pathophysiology of AF, we investigated profibrotic factors in different subsets of circulating monocytes obtained from patients with atrial fibrillation undergoing catheter ablation.
Mechanisms of maintenance of both atrial fibrillation and structural left ventricular disease are known to include fibrosis. Galectin-3, a biomarker of fibrosis, is elevated both in patients with heart failure and persistent atrial fibrillation. We sought to find whether galectin-3 has a prognostic value in patients with heart failure and a reduced left ventricular ejection fraction undergoing ablation of persistent atrial fibrillation.
Epicardial adipose tissue (EAT) is associated with atrial fibrillation (AF), but the underlying mechanisms remain to be fully elucidated.
