Atrialfibrillation and venous thromboembolism: evidence of bidirectionality in the Atherosclerosis Risk in Communities Study Essentials Atrialfibrillation (AF) may increase risk of venous thromboembolism (VTE), and vice versa. Bidirectionality was assessed prospectively via data from 15 129 black and white individuals. AF was associated with greater risk of developing VTE, and VTE with greater risk of AF. Associations were strongest among blacks and in the first 6 months after initial (...) diagnosis.Background Atrialfibrillation (AF) and venous thromboembolism (VTE) frequently co-occur. These conditions have shared risk factors and are accompanied by coagulation abnormalities. Furthermore, mechanistic pathways may directly link the disorders. Objectives To test the hypothesis that individuals with incident AF are at greater risk of developing VTE, and those with VTE are at elevated risk of AF. We also tested whether associations were stronger in the first 6 months after the initial diagnosis
Selective screening for atrialfibrillation using multivariable risk models Atrialfibrillation can lead to stroke if untreated, and identifying those at higher risk is necessary for cost-effective screening for asymptomatic, paroxysmal atrialfibrillation. Age has been proposed to identify those at risk, but risk models may provide better discrimination. This study compares atrialfibrillation risk models with age for screening for atrial fibrillation.Nine atrialfibrillation risk models were (...) compared using the Atherosclerosis Risk in Communities study (11 373 subjects, 60.0±5.7 years old). A new risk model (Screening for Asymptomatic AtrialFibrillation Events-SAAFE) was created using data collected in the Monitoring Disparities in Chronic Conditions study (3790 subjects, 58.9±15.3 years old). The primary measure was the fraction of incident atrialfibrillation subjects who should receive treatment due to a high CHA2DS2-VASc score identified when screening a fixed number equivalent
Lifetime risk of atrialfibrillation according to optimal, borderline, or elevated levels of risk factors: cohort study based on longitudinal data from the Framingham Heart Study. To examine the association between risk factor burdens-categorized as optimal, borderline, or elevated-and the lifetime risk of atrial fibrillation.Community based cohort study.Longitudinal data from the Framingham Heart Study.Individuals free of atrialfibrillation at index ages 55, 65, and 75 years were assessed (...) . Smoking, alcohol consumption, body mass index, blood pressure, diabetes, and history of heart failure or myocardial infarction were assessed as being optimal (that is, all risk factors were optimal), borderline (presence of borderline risk factors and absence of any elevated risk factor), or elevated (presence of at least one elevated risk factor) at index age.Lifetime risk of atrialfibrillation at index age up to 95 years, accounting for the competing risk of death.At index age 55 years, the study
Association between incidence of atrialfibrillation and duration of cardiopulmonary bypass in coronary artery bypass graft surgery (CABG): a cohort study Open heart surgery is one of the most common and valuable treatment methods for cardiovascular diseases, a common side effect of which is atrialfibrillation that occurs due to various reasons.To determine the relationship between incidence of atrialfibrillation (AF) and duration of cardiopulmonary bypass (CPB) in patients after open heart (...) of the patients was 61.76±9.2, the majority of the patients (70.1%) were male. The association between Incidence of AtrialFibrillation and cardiopulmonary pump time (minute) was not meaningful. Incidence of atrialfibrillation had statistically significant relationship with variables of mean age, BMI, PAC, PVC, creatinine and duration of hospitalization (p<0.05); on the other hand, variables of gender, cross clamp time (minute), intubation time (hour), and clinical history had no effect on atrial
Digoxin and Mortality in Patients With AtrialFibrillation Digoxin is widely used in patients with atrialfibrillation (AF).The goal of this paper was to explore whether digoxin use was independently associated with increased mortality in patients with AF and if the association was modified by heart failure and/or serum digoxin concentration.The association between digoxin use and mortality was assessed in 17,897 patients by using a propensity score-adjusted analysis and in new digoxin users
Apixaban in patients at risk of stroke undergoing atrialfibrillation ablation It is recommended to perform atrialfibrillation ablation with continuous anticoagulation. Continuous apixaban has not been tested.We compared continuous apixaban (5 mg b.i.d.) to vitamin K antagonists (VKA, international normalized ratio 2-3) in atrialfibrillation patients at risk of stroke a prospective, open, multi-centre study with blinded outcome assessment. Primary outcome was a composite of death, stroke (...) , or bleeding (Bleeding Academic Research Consortium 2-5). A high-resolution brain magnetic resonance imaging (MRI) sub-study quantified acute brain lesions. Cognitive function was assessed by Montreal Cognitive Assessment (MoCA) at baseline and at end of follow-up. Overall, 674 patients (median age 64 years, 33% female, 42% non-paroxysmal atrialfibrillation, 49 sites) were randomized; 633 received study drug and underwent ablation; 335 undertook MRI (25 sites, 323 analysable scans). The primary outcome
How to Prevent, Detect and Manage Complications Caused by Cryoballoon Ablation of AtrialFibrillationAtrialfibrillation is the most common cardiac arrhythmia and the prevalence is increasing every year. Patients who fail to maintain sinus rhythm with use of anti-arrhythmic drug therapy are referred for catheter ablation. Cryoballoon (CB) ablation has emerged as an effective and alternative treatment option to traditional point-by-point radiofrequency ablation, but there can be complications (...) . This article reviews the incidence, presentation, risk factors, management and preventative strategies of three major complications associated with CB ablation: phrenic nerve injury, atrial oesophageal fistula and bronchial injury. Although these complications are rare, electrophysiologists should institute measures to identify high-risk patients, implement best-practice techniques to minimise risks and maintain a high index of suspicion to recognise the complications quickly and implement correct
Drivers of AtrialFibrillation: Theoretical Considerations and Practical Concerns Understanding the mechanisms responsible for driving AF is key to improving the procedural success for AF ablation. In this review, we look at some of the proposed drivers of AF, the disagreement between experts and the challenges confronted in attempting to map AF. Defining a 'driver' is also controversial, but for the purposes of this review we will consider an AF driver to be either a focal or localised source

Systematic Screening for AtrialFibrillation in the Community: Evidence and Obstacles With an ageing population globally, the burden of atrialfibrillation (AF) and its consequent complication of stroke and risk of mortality will continue to increase. Although opportunistic screening for AF by pulse check or ECG rhythm strip for people >65 years of age is currently recommended, data are now emerging that demonstrate the possible benefits of systematic community screening. Such screening
Stroke Risk in Patients With Reduced Ejection Fraction After Myocardial Infarction Without AtrialFibrillation Stroke can occur after myocardial infarction (MI) in the absence of atrialfibrillation (AF).This study sought to identify risk factors (excluding AF) for the occurrence of stroke and to develop a calibrated and validated stroke risk score in patients with MI and heart failure (HF) and/or systolic dysfunction.The datasets included in this pooling initiative were derived from 4 trials
New-Onset AtrialFibrillation After PCI or CABG for Left Main Disease: The EXCEL Trial There is limited information on the incidence and prognostic impact of new-onset atrialfibrillation (NOAF) following percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) for left main coronary artery disease (LMCAD).This study sought to determine the incidence of NOAF following PCI and CABG for LMCAD and its effect on 3-year cardiovascular outcomes.In the EXCEL (Evaluation (...) of XIENCE Versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization) trial, 1,905 patients with LMCAD and low or intermediate SYNTAX scores were randomized to PCI with everolimus-eluting stents versus CABG. Outcomes were analyzed according to the development of NOAF during the initial hospitalization following revascularization.Among 1,812 patients without atrialfibrillation on presentation, NOAF developed at a mean of 2.7 ± 2.5 days after revascularization in 162 patients
Female Sex Is a Risk Modifier Rather Than a Risk Factor for Stroke in AtrialFibrillation: Should We Use a CHA2DS2-VA Score Rather Than CHA2DS2-VASc? Stroke risk in atrialfibrillation is assessed by using the CHA2DS2-VASc score. Sex category (Sc, ie, female sex) confers 1 point on CHA2DS2-VASc. We hypothesized that female sex is a stroke risk modifier, rather than an overall risk factor, when added to a CHA2DS2-VA (sex-independent thromboembolism risk) score scale.Using 3 nationwide registries (...) , we identified patients with incident nonvalvular atrialfibrillation from January 1, 1997, through December 31, 2015. Patients receiving oral anticoagulant treatment at baseline were excluded, and person-time was censored at the time of treatment initiation (if any). CHA2DS2-VA scores were calculated for men and women, and were followed for up to 1 year in the Danish National Patient Registry. The primary outcome was a primary hospital code for ischemic stroke or systemic embolism
Targeted therapy of underlying conditions improves sinus rhythm maintenance in patients with persistent atrialfibrillation: results of the RACE 3 trial Atrialfibrillation (AF) is a progressive disease. Targeted therapy of underlying conditions refers to interventions aiming to modify risk factors in order to prevent AF. We hypothesised that targeted therapy of underlying conditions improves sinus rhythm maintenance in patients with persistent AF.We randomized patients with early persistent AF
