OBJECTIVES: This study sought to examine the efficacy of low-level vagus nerve stimulation (LLVNS) in suppressing post-operative atrial fibrillation (POAF) and inflammatory cytokines in patients undergoing cardiac surgery. BACKGROUND: POAF often complicates cardiac surgery. METHODS: Patients undergoing cardiac surgery were randomized to active or sham LLVNS. In all patients, a bipolar wire was sutured to the vagus nerve pre-ganglionic fibers alongside the lateral aspect of the superior vena cava...

Although the cardiovascular benefits of moderate exercise are well established, there is growing epidemiological support for the notion that high-intensity endurance athletics increases the risk of atrial fibrillation (AF). There are many gaps in evidence related to epidemiology and mechanisms of AF in endurance athletes. The proposed pathophysiological mechanisms include alterations of autonomic tone, electrical remodeling, anatomical remodeling, fibrosis, and inflammation. Clinical management of the athlete with AF often includes a period of decreased frequency, intensity, and duration of exercise with assessment for improvement in AF recurrence...

BACKGROUND: Obesity, characterized by systemic low-grade inflammation, is considered a well-known risk for atrial fibrillation. In fact, IL-10 (interleukin 10), which is a potent anti-inflammatory cytokine, has been reported to decrease in obese and diabetic patients. We tested the hypotheses forwarding that genetic deletion of IL-10 exacerbates high-fat diet (HFD)-induced obesity-caused atrial inflammation, lipidosis, fibrosis, and fibrillation and that IL-10 therapy inhibits this pathology...

Nesfatin-1, a newly discovered adipokine, inhibits inflammatory response. Inflammation is involved in the mechanism of atrial fibrillation (AF). We aim to determine the association between serum nesfatin-1 concentrations and AF. A population of 200 patients with AF and 108 patients without AF were enrolled in this study. These patients were divided into three subgroups of paroxysmal AF, persistent AF, and permanent AF. Serum nesfatin-1 concentrations were lower in AF patients than in controls. Logistic regression analysis showed that serum nesfatin-1 concentrations were inversely associated with AF...

In a previous report of two married cohabiting couples affected by polymyalgia rheumatica (PMR), we noticed that the wife of one couple and both members of the other couple suffered from symptomatic diverticular disease (DD), whose diagnosis was made before the onset of PMR. We investigated whether DD might be a risk factor for the development of PMR. We conducted a case-control study informed on a database containing the prospectively collected medical records of consecutive PMR patients. Among comorbidities, attention was focused on symptomatic DD, provided that the diagnosis had been made by colonoscopy and/or computed tomography scan...

Atrial fibrillation (AF) is the most common cardiac arrhythmia, and its incidence is increasing worldwide. One method used to restore sinus rhythm is direct current cardioversion (DCCV). Despite the high success rate of DCCV, AF typically recurs within the first 2 weeks. However, our understanding of the pathophysiology of AF recurrence, incidence, and progression are highly limited. Lipidomic profiling was applied to identify altered lipids in plasma from patients with AF using ultra-performance liquid chromatography/quadrupole time-of-flight mass spectrometry coupled with multivariate statistical analysis...

Aims: Oesophagogastroduodenoscopy (OGD) after catheter ablation (CA) of atrial fibrillation (AF) revealed a high rate of procedure related oesophageal lesions. We hypothesized that magnetically guided CA with careful radiofrequency energy titration at the posterior left atrial (LA) wall limits the incidence of oesophageal tissue damage. Methods and results: As a part of the prospective "Remote MAGNetic catheter Ablation for Atrial Fibrillation" (MAGNA-AF) registry, 251 out of 266 consecutive patients underwent OGD after magnetically guided single-CA for AF...

BACKGROUND: There are several mechanisms, including inflammation, oxidative stress and abnormal calcium homeostasis, involved in the pathogenesis of atrial fibrillation. In diabetes mellitus (DM), increased oxidative stress may be attributable to higher xanthine oxidase activity. In this study, we examined the relationship between oxidative stress and atrial electrical and structural remodeling, and calcium handling abnormalities, and the potential beneficial effects of the xanthine oxidase inhibitor allopurinol upon these pathological changes...

Cardiovascular diseases are the leading cause of death worldwide. Endothelial dysfunction, inflammation and oxidative stress are at the forefront in the onset and development of atherosclerosis and many cardiovascular diseases. Epidemiological evidence is that low serum albumin levels are linked to incident ischemic heart disease, heart failure, atrial fibrillation, stroke and venous thromboembolism, independent of risk factors, body mass index and inflammation. Hypoalbuminemia has also emerged as an independent prognosticator in many cardiovascular diseases, such as coronary artery disease, heart failure, congenital heart disease, infective endocarditis and stroke, even after adjusting for usual causal factors and prognostic markers...

BACKGROUND: Atrial fibrillation (AF) is the most prevalent cardiac arrhythmia in the general population and is associated with an increased number of adverse outcomes. The onset and maintenance of this arrhythmia requires a trigger event and the presence of a predisposing substrate. Atrial fibrosis, a major characteristic of AF-related structural remodeling, represents a process closely related to inflammation as demonstrated by emerging evidence. Aim of this article is to review the evidence linking AF to systemic autoimmune diseases...

INTRODUCTION: Atrial high-rate episodes (AHREs) are associated with an increased risk of developing atrial fibrillation and thromboembolism. The characteristics of 'real world' patients developing AHREs are poorly known. METHODS: We included 496 consecutive patients with cardiac implantable electronic devices (CIEDs). Primary endpoint was occurrence of AHREs, defined as > 175 bpm and lasting > 5 min, in a median follow-up of 16.5 (IQR 3.9-38.6) months (1082...

OBJECTIVE: Application of therapeutic mild hypothermia in patients after resuscitation, often accompanied by myocardial infarction, cardiogenic shock and systemic inflammation may impact on cardiac rhythm. We therefore tested susceptibility to atrial arrhythmias during hyperthermia (HT, 40.5°C), normothermia (NT, 38.0°C) and mild hypothermia (MH, 33.0°C). METHODS: Nine healthy, anesthetized closed-chest landrace pigs were instrumented with a quadripolar stimulation catheter in the high right atrium and a decapolar catheter in the coronary sinus...

To examine the association between serum magnesium and incident heart failure (HF) in older men and investigate potential pathways including cardiac function, inflammation and lung function. Prospective study of 3523 men aged 60-79 years with no prevalent HF or myocardial infarction followed up for a mean period of 15 years, during which 268 incident HF cases were ascertained. Serum magnesium was inversely associated with many CVD risk factors including prevalent atrial fibrillation, lung function (FEV1 ) and markers of inflammation (IL-6), endothelial dysfunction (vWF) and cardiac dysfunction [NT-proBNP and cardiac troponin T (cTnT)]...

Traditionally, cognitive impairment has been associated not only with ageing itself but also with concomitant comorbidities that interact in the disease continuum from the prodromic phases. Notable among these are delirium, nutritional alterations, balance and gait, infections and even a progressive incidence of neoplasms. However, with regard to diagnosis and staging, clinicians should perhaps remain especially alert to the possibility of pharmacological iatrogeny, which is not limited to psychopharmacological treatment...

We aimed to characterize of the role of insulin-like growth factor-binding protein 7 (IGFBP-7) in heart failure (HF) pathophysiology. IGFBP-7 has been associated with cardiac hypertrophy and diastolic dysfunction in HF. In 86 patients with HF with a preserved ejection fraction (HFpEF) (ejection fraction [EF] ≥45%) and 79 with HF with a reduced ejection fraction (HFrEF), we assessed concentrations of serum IGFBP-7, correlations between serum IGFBP-7 and clinical data, diastolic function, and associations with outcome...

The concurrence of atrial fibrillation and acute coronary syndrome poses a conundrum in the antithrombotic management as intensification of anticoagulation or antiplatelet therapy inevitably comes at the price of an increased bleeding risk. Various antithrombotic combinations have been attempted to prevent the recurrent cardiovascular events, however, there has been limited success in effective risk reduction for this high risk population. Given the overarching effect of interleukin 1β-driven inflammation on the arrhythmogenesis, thrombogenesis, and hypercoagulability, we hypothesize that the triple-pathway strategy (i...

INTRODUCTION: High mobility group box 1 (HMGB1) is a member of the HMGB family that is involved in inflammatory disease-related thrombosis. We hypothesize that HMGB1 and its downstream factors are associated with thrombosis in atrial fibrillation (AF). MATERIALS AND METHODS: Our experimental materials were the left atrial appendage (LAA) tissues from patients undergoing valve replacement. The samples were divided into 3 groups: a sinus rhythm group (n = 15), an AF(+)thrombus(-)group (n = 15), and an AF(+) thrombus (+)group (n = 15)...

PURPOSE: We sought to determine whether insulin-sensitizing therapy (thiazolidinediones and/or metformin) decreased risk of developing atrial fibrillation compared with insulin-providing therapy (insulin, sulfonylurea, and/or a meglitinide). BACKGROUND: Thiazolidinediones are insulin-sensitizers that also decrease the inflammatory response. Since inflammation is a risk factor for atrial fibrillation, we hypothesized that treating diabetes with thiazolidinediones might decrease the risk of developing atrial fibrillation...

BACKGROUND: Link between inflammation and atrial fibrillation (AF) has been increasingly recognized. Neopterin, a biomarker of cellular immune activation, may be associated with incident AF. OBJECTIVE: To investigate the association between plasma neopterin levels and risk of an inpatient hospital diagnosis of AF, and to evaluate a joint association of neopterin and a nonspecific inflammatory marker C-reactive protein (CRP) in two prospective cohorts. METHODS: We performed a prospective analysis from a community-based cohort (the Hordaland Health Study (HUSK), n = 6891), and validated the findings in a cohort of patients with suspected stable angina pectoris (the Western Norway Coronary Angiography Cohort (WECAC), n = 2022)...
