Clinical and experimental data support a critical role for inflammation in cardiovascular disease. The purpose of the current study was to examine the relation between an inflammatory marker, neutrophil-to-lymphocyte ratio (NLR), and incident atrial fibrillation (AF) in asymptomatic adults. We investigated 21,118 self-referred men and women who were annually screened in a tertiary medical center. All subjects were free of AF at baseline and had their serum NLR calculated at the first annual visit. Subjects were divided into 2 groups based on their baseline NLR: Low (<2...

BACKGROUND: Left atrial (LA) electro-anatomical remodeling and diameter increase in atrial fibrillation (AF) indicates disease progression and is associated with poor therapeutic success. Furthermore, AF leads to a hypercoagulable state, which in turn promotes the development of a substrate for AF and disease progression in the experimental setting. The aim of this study was to identify pathways associated with LA remodeling in AF patients using untargeted proteomics approach. METHODS: Peripheral blood samples of 48 patients (62±10 years, 63% males, 59% persistent AF) undergoing AF catheter ablation were collected before ablation...

Botulinum toxin injection on epicardial fat, which inhibits acetylcholine (ACh) release, reduced the presence of atrial fibrillation (AF) in patients after heart surgery. Thus, we wanted to study the profile of the released proteins of epicardial adipose tissue (EAT) under cholinergic activity (ACh treatment) and their value as AF predictors. Biopsies, explants, or primary cultures were obtained from the EAT of 85 patients that underwent open heart surgery. The quantification of muscarinic receptors (mAChR) by real-time polymerase chain reaction or western blot showed their expression in EAT...

Renal dysfunction results in the accumulation of various uremic toxins, including indoxyl sulphate (IS), and is a major risk factor for atrial fibrillation (AF). Experimental studies have demonstrated that IS exacerbates atrial remodelling via oxidative stress, inflammation, and fibrosis. However, its clinical impact on AF-promoting cardiac remodelling has not been described. Therefore, the purpose of this study was to clarify the relationship between basal IS levels and the 1-year outcomes after catheter ablation for the treatment of AF...

BACKGROUND: Inflammation has been reported to cause atrial fibrillation (AF). However, it remains unclear whether C-reactive protein (CRP) levels predict AF. We investigated whether there was an association between serum CRP levels and the development of AF. METHODS: A total of 10,030 subjects aged between 40 and 69 years were enrolled and followed biennially over a 12-year period in the Ansan-Ansung cohort study. Serum CRP levels were measured at baseline and high-sensitivity CRP (hsCRP) levels were measured at every revisit...

Global obesity rates have nearly tripled since 1975. This obesity rate increase is mirrored by increases in atrial fibrillation (AF) that now impacts nearly 10% of Americans over the age of 65. Numerous epidemiologic studies have linked incidence of AF and obesity and other obesity-related diseases, including hypertension and diabetes. Due to the wealth of epidemiologic data linking AF with obesity-related disease, mechanisms of AF pathogenesis in the context of obesity are an area of ongoing investigation...

A wealth of clinical and epidemiological evidence has linked obesity to a broad spectrum of cardiovascular diseases (CVD) including coronary heart disease, heart failure, hypertension, stroke, atrial fibrillation and sudden cardiac death. Obesity can increase CVD morbidity and mortality directly and indirectly. Direct effects are mediated by obesity-induced structural and functional adaptations of the cardiovascular system to accommodate excess body weight, as well as by adipokine effects on inflammation and vascular homeostasis...

OBJECTIVE: Technological advances have allowed cardiac implantable electronic devices (CIEDs) to detect, analyze, and store atrial high-rate episodes (AHREs), which are surrogate for the term silent atrial fibrillation (AF). The association of AHREs with adverse clinical events has been demonstrated in several recent studies, implying that morbidity and mortality can be significantly prevented by prompt recognition and intervention. Inflammation and oxidative stress are among several mechanisms that contribute to the pathogenesis of AF...

Prevalence of obesity, metabolic syndrome (MetS) and type 2 diabetes (T2D) is growing alarmingly, and the number of affected people continues to escalate. Such cardiometabolic states exert many deleterious effects on the heart as they are associated with adverse left ventricular (LV) remodelling and, most notably, with a marked increase in the risk of developing atrial fibrillation (AF) and subsequent stroke. Epidemiological studies clearly show a strong association between obesity and AF, with a 4-5% increase in AF risk for every unit increase in BMI...

Atrial fibrillation (AF) is prevalent in nearly 27% of patients with stage 5 chronic kidney disease on hemodialysis (CKD5-HD), suggesting a strong association between these 2 pathologies. It is hypothesized that the relationship between these 2 diseases may be mediated by inflammation. Angiopoietin-2 (Ang-2), a pro-inflammatory biomarker of endothelial instability, inflammation, and vascular remodeling, is elevated in CKD5-HD and AF, yet has not been evaluated in patients with concomitant AF and CKD5-HD. The aim of this study is to analyze circulating levels of inflammatory and thrombotic biomarkers in patients with concomitant AF and CKD5-HD...

BACKGROUND: Atrial fibrosis is a hallmark of structural remodeling in atrial fibrillation (AF). Plasma procollagen type III N-terminal propeptide (PIIINP) reflects collagen synthesis and degradation while collagen type I carboxy-terminal telopeptide (ICTP) reflects collagen degradation. We aimed to study baseline plasma PIIINP and ICTP and their associations with incident AF in participants initially free of overt cardiovascular disease. METHODS: In a stratified sample of the Multi-Ethnic Study of Atherosclerosis, initially aged 45-84 years, 3071 participants had both PIIINP and ICTP measured at baseline...

Type 2 diabetes mellitus (T2DM) substantially increases the risk of cardiovascular events, including heart failure (HF), due to complications such as hypertension, obesity and dyslipidemia based on metabolic syndrome, which plays the central pathological role in HF. A reason is that T2DM causes left ventricular (LV) diastolic dysfunction beginning in the early phase of the disease, which in turn increases the risk of development of HF independently of the control of blood glucose levels, blood pressure or the presence of coronary artery diseases...

Background: Atrial fibrillation (AF) is one of the widest spread forms of arrhythmia, which is associated with the increased mortality and thromboembolic complications. To date, the involvement of renin-angiotensin-aldosterone system and immunomediators of inflammation into the mechanisms of development and maintenance of isolated AF is not clear. Specificity of their changes with respect to the latent myocarditis at AF is not proved. Methods: In 96 patients with persistent isolated atrial fibrillation (IsAF), scheduled for radiofrequency ablation and endomyocardial biopsy (EMB), and in 20 healthy volunteers (HVT), levels of plasma tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, IL-6, IL-8, IL-10, fatty acid-binding protein (FABP), neopterin, C-reactive protein (CRP) were determined by ELISA, level of aldosterone and the renin activity were determined by radioimmunoassay...

BACKGROUND: Post cardiac injury syndrome (PCIS) is a troublesome but not uncommon complication following catheter ablation of arrhythmias. We aimed to study the clinical features of ablation-associated PCIS. METHODS: For this purpose, we conducted a computerised literature search that identified 19 published cases, and we additionally included another 2 new cases from our centres. Twenty-one cases of PCIS following ablation were analysed. RESULTS: Among the 21 cases, PCIS most commonly occurred after atrial flutter/fibrillation (AFL/AF) ablation (71...

BACKGROUND AND AIMS: We aimed to evaluate the associations and prognostic value of interleukin-6 (IL6) for the prediction of atherosclerotic cardiovascular disease (ASCVD) events, heart failure (HF), and other chronic diseases in a large, multi-ethnic, contemporary population. METHODS: We included 6617 participants from the Multi-Ethnic Study of Atherosclerosis (5640 non-users, 977 users of statins at baseline). Main outcomes were hard ASCVD events and HF; secondary outcomes included all-cause death, atrial fibrillation, venous thromboembolism and cancer...

Atrial fibrillation (AF) is the most common arrhythmia in adults, and its incidence and prevalence increase with age. The risk of cognitive impairment and dementia also increases with age, and both AF and cognitive impairment or dementia share important risk factors. In meta-analyses of published studies, AF is associated with a 2.4-fold and 1.4-fold increase in the risk of dementia in patients with or without a history of stroke, respectively. This association is independent of shared risk factors such as hypertension and diabetes mellitus...

AIMS: Left atrial (LA) structural remodelling develops in rheumatic heart disease (RHD) according to the disease severity of the mitral valve and the presence of atrial fibrillation. Sustained active inflammation has been previously reported in the LA of patients with RHD, suggesting a direct role of cell-mediated immunity in the pathogenesis of LA remodelling. Dendritic cells (DCs) have a major antigen-presenting role, and are known as crucial modulators of innate and adaptive immunity...

Objectives: Atrial fibrillation has been associated with obesity in epidemiological studies. Epicardial adipose tissue is an ectopic fat depot in the proximity of atria, with endocrine and inflammatory properties that is implicated in the pathophysiology of atrial fibrillation. Inflammation also has a role in atrial arrhythmogenesis. The aim of this study was to investigate the potential relations of epicardial adipose tissue to left atrial size and to adiponectin and the pro-inflammatory mediators, high-sensitivity C-reactive protein, and interleukin-6 in paroxysmal and permanent atrial fibrillation...
