BACKGROUND: The optimal long-term antithrombotic treatment of patients with stable coronary artery disease (CAD) and atrial fibrillation (AF) is a challenge in daily practice. We sought to determine the prevalence of hemorrhagic complications and ischaemic events depending on antithrombotic strategy in patients with stable CAD and AF. METHODS: The primary outcome was major adverse cardiac and cerebrovascular events (MACCE) defined as a composite of cardiovascular mortality, myocardial infarction and ischaemic stroke...

BACKGROUND: The anticoagulation of atrial fibrillation catheter ablation during the perioperative stage does matter and should be treated with discretion. We aimed to assess impact of three important genes participating in vitamin K cycle (i.e. VKORC1 rs9923231, CYP4F2 rs2108622 and NQO1 rs1800566) on the daily stable warfarin dose requirement in Sichuan Han Chinese patients with catheter ablation of atrial fibrillation. METHODS: A total of 222 atrial fibrillation patients taking stable warfarin therapy after catheter ablation operation were enrolled in this study...

INTRODUCTION: Atrial fibrillation might increase the risk of dementia. We aim to test the hypothesis that dementia could reclassify the actual risk of stroke and death predicted by the CHA2DS2-VASc in patients with atrial fibrillation (AF). METHODS: A prospective study performed in a specific health care area. RESULTS: From our health care area (n = 348,985), throughout 2013, AF was codified in 7,990 (2.08%). Mean age was 76.83 ± 10.5, mean CHA2DS2-VASc = 3...

BACKGROUND:  Stroke risk in atrial fibrillation (AF) is often assessed at initial presentation, and risk stratification performed as a 'one off'. In validation studies of risk prediction, baseline values are often used to 'predict' events that occur many years later. Many clinical variables have 'dynamic' changes over time, as the patient is followed up. These dynamic changes in risk factors may increase the CHA2 DS2 -VASc score, stroke risk category and absolute ischaemic stroke rate...

INTRODUCTION: Pericardial effusion/tamponade (PE/PT) is a rare but serious complication following left atrial appendage closure (LAAC). It may be speculated that LAA contraction during sinus rhythm (SR) exerts mechanical force on the device that eventually leads to PE. We sought to determine the incidence and predictors of PE following LAAC using Watchman with special emphasis on the underlying heart rhythm during implant. METHODS AND RESULTS: From 47 centers in 13 European countries 1020 patients underwent LAAC and data on baseline rhythm were available from 1010 patients (mean age 73 ± 9 years, 60% male, median CHA2DS2-VASc = 4)...

Hypertension has been found to be increased a risk of stroke in atrial fibrillation (AF). Both the European and U.S. guidelines advocate the use of the CHA2 DS2 -VASc (congestive heart failure, hypertension, age > 75 years, diabetes mellitus, stroke/transient ischemic attack, vascular disease, age 65-74 years, sex category) scheme for risk stratification. Although vitamin K antagonists is more effective than acetylsalicylic acid at preventing ischaemic stroke, its benefit is offs by an increased haemorrhage risk...

Introduction: No-reflow is one of the major complications of primary PCI in patients with acute ST elevation myocardial infarction. This phenomenon is associated with adverse outcomes in these patients. In the current study, we evaluated the effectiveness of CHA2DS2-VASc score in predicting no-reflow phenomenon. CHA2DS2-VASc score is a risk stratification method to estimate the risk of thromboembolism in patients with atrial fibrillation. Methods: In total, 396 patients with ST elevation myocardial infarction who had undergone primary PCI were evaluated in our study...

Aims: Left atrial (LA) remodelling is a key determinant of atrial fibrillation (AF) ablation outcome. Optimal methods to assess this process are scarce. LA sphericity is a shape-based parameter shown to be independently associated to procedural success. In a multicentre study, we aimed to test the feasibility of assessing LA sphericity and evaluate its capability to predict procedural outcomes. Methods and results: This study included consecutive patients undergoing first AF ablation during 2013...

Aims: We sought to evaluate the relationship between left atrial (LA) mechanical dyssynchrony and history of stroke or transient ischaemic attack (TIA) in patients with atrial fibrillation (AF). We hypothesized that mechanical dyssynchrony of the LA is associated with history of stroke/TIA independent of LA function and Cardiac failure, Hypertension, Age, Diabetes, Stroke/transient ischaemic attack (TIA), VAscular disease, and Sex category (CHA2DS2-VASc) score in patients with AF. Methods and results: We conducted a cross-sectional study of 246 patients with a history of AF (59 ± 10 years, 29% female, 26% non-paroxysmal AF) referred for catheter ablation to treat drug-refractory AF who underwent preablation cardiac magnetic resonance (CMR) in sinus rhythm...

The prevalence of chronic kidney disease (CKD) is high in patients with atrial fibrillation (AF). Left atrial appendage closure (LAAC) has been recognized as an efficient alternative to oral anticoagulation for the prevention of thromboembolic events in patients with non-valvular AF (NVAF); however, the long-term safety and efficacy of LAAC in patients with CKD remain unclear. This study was designed to provide data regarding the safety and efficacy of LAAC in NVAF patients with CKD. A real-world analysis of the safety and efficacy of LAAC was performed on a cohort of 300 NVAF patients with or without CKD who underwent LAAC using the Watchman (WM) device at our center...
