OBJECTIVES: We aim to determine the benefit of two different doses magnesium sulfate (MgS) compared to placebo in rate control of rapid atrial fibrillation (AF) managed in the emergency department (ED). METHODS: We undertook a randomized, controlled, double-blind clinical trial in 3 university hospital EDs between August 2009 and December 2014. Patients >18years with rapid AF (>120 bpm) were enrolled and randomized to 9g intravenous MgS (High dose group, n=153), 4...

The interruption of oral anticoagulation therapy (OAC) after CA of atrial fibrillation (AF) is controversial. The purpose of this study was to evaluate the relationship between successful long-term outcomes of catheter resection and SR maintenance and ischemic stroke risk in Korea. We studied 1,548 consecutive patients who were followed up for more than 2 years after CA of AF. We investigated the incidence of ischemic stroke during long-term follow-up. Compared to the AF recurrence group (n = 619), the sinus rhythm (SR) maintenance group (n = 929) had more paroxysmal AF (74...

Catheter ablation has been wildly used to treat atrial fibrillation (AF) and has achieved a better efficacy for paroxysmal AF (PAF) but not for persistent AF (PerAF). Furthermore, a few data on the efficacy and safety of catheter ablation for PerAF were reported. This study aimed to investigate long-term efficacy of radiofrequency catheter ablation (RFCA) for PerAF and explore predictors of late recurrence of atrial fibrillation (LRAF).A total of 92 consecutive patients with PerAF (64 males, aged 56.42 ± 11...

This report is a description of a rare case of transient ST-segment elevation during cryoballoon application for paroxysmal atrial fibrillation (PAF). A 74-year-old male with symptomatic PAF was referred to the center for ablation. During cryoablation of the left superior pulmonary vein (188 seconds, -48°C), ST-segment elevation in the anterolateral leads was observed suddenly, though without any significant complaint. Upon the increase in the ST segment, the cryoapplication was immediately terminated. Coronary artery angiography was performed less than 5 minutes after balloon deflation and demonstrated coronary slow flow with a corrected Thrombolysis In Myocardial Infarction (TIMI) frame count of 48...

Purpose: To estimate the incidence of postprocedural early cardiac complications among patients undergoing transcatheter aortic valve implantation, through transapical approach (TA-TAVI), and to identify factors independently associated with the occurrence of them. Patients and methods: A retrospective cohort study of 90 patients, who had undergone TA-TAVI in a tertiary hospital of Liverpool, UK, during a 5-year period (September 2008-October 2013), was conducted...

Background: Atrial fibrillation (AF) occurs frequently in patients with COPD. There are limited data about the impact of AF in hospitalized COPD patients on other serious health outcomes, such as acute organ dysfunction, severe sepsis, and respiratory failure. The aim of our study was to delineate the impact of AF in hospitalized COPD patients. Methods: We defined COPD populations with and without AF from the National Health Insurance database in Taiwan. The control subjects (patients with COPD without AF) were selected from the population of COPD patients who had no history of AF and were matched to the COPD patients with AF by age (±1 year), gender, and the year of COPD diagnosis (±1 year)...

Historically, because of the difficulty of using warfarin safely and effectively, many patients with cardioembolic stroke who should have been anticoagulated were instead given ineffective antiplatelet therapy (or no antithrombotic therapy). With the arrival of new oral anticoagulants that are not significantly more likely than aspirin to cause severe haemorrhage, everything has changed. Because antiplatelet agents are much less effective in preventing cardioembolic stroke, it is now more prudent to anticoagulate patients in whom cardioembolic stroke is strongly suspected...

INTRODUCTION: Interatrial block (IAB) is strongly associated with recurrence of atrial fibrillation (AF) in different clinical scenarios. Atrial fibrosis is considered the responsible mechanism underlying the pathogenesis of IAB. The aim of this study was to investigate whether IAB predicted AF at 12 months follow up in a population of patients with ST segment elevation myocardial infarction (STEMI). METHODS: Prospective, single center, observational study of patients presenting with ST-segment elevation myocardial infarction (STEMI) and referred to primary percutaneous coronary intervention (P-PCI)...

BACKGROUND: Novel oral anticoagulation (NOAC) has been introduced in recent years, but data on use in atrial fibrillation (AF) in primary care setting is scarce. In Germany, General Practitioners are free to choose type of oral anticoagulation (OAC) in AF. Our aim was to explore changes in prescription-rates of OAC in German primary care before and after introduction of NOAC on the market. METHODS: Data of a representative morbidity registration project in primary care in Germany (CONTENT) were analysed...

BACKGROUND AND OBJECTIVES: 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. METHODS: Monocyte counts were obtained from blood samples in 881 AF patients. Study outcomes were (i) all-cause death; (ii) major adverse cardiovascular events; (iii) stroke, TIA or other systemic embolism (SSE); and (iv) major bleeding...

Aims: To investigate the causes of death and the associated clinical factors in patients with atrial fibrillation (AF) in the contemporary clinical practice. Methods and Results: The Fushimi AF Registry is a community-based prospective survey of AF patients since March 2011 in Fushimi-ku, Kyoto. We investigated causes of death and the clinical indicators of cardiovascular (CV) and non-CV death in 4,045 patients with available follow-up data by the end of November 2016...

Aims: To compare the effectiveness and safety of standard dose rivaroxaban (20 mg once daily) and warfarin in nonvalvular atrial fibrillation (NVAF) patients with a non-sex-related CHA2DS2-VASc score of 1. Methods and Results: Analysis of United States Truven MarketScan claims from 11/2011-12/2016 for anticoagulant-naïve NVAF patients with a single non-sex-related stroke risk factor assigned 1-point in the CHA2DS2-VASc score and ≥12-months of continuous medical/prescription insurance coverage prior to the qualifying oral anticoagulant dispensing...

BACKGROUND: Heart rate (HR) assessed by electrocardiogram (ECG-HR) and pulse rate (PR) measured in a physician's office (office-PR) are taken with subjects in different body positions-i.e., supine vs. sitting. Although analysis of HR differences according to body position could provide new practical insights, there have been few studies on the subject. We herein investigated whether the difference between office-PR and ECG-HR (delta HR) was associated with brain natriuretic peptide (BNP) levels and left ventricular mass (LVM)...

PURPOSE OF REVIEW: Non-valvular atrial fibrillation is common in patients with severe chronic kidney disease (CKD) and historically patients have been treated with vitamin K antagonists (VKA). However, these agents have questionable efficacy and are associated with increased bleeding risk. Non-vitamin K oral anticoagulants (NOAC) have advantages over VKA in early stage CKD. In this review, we sought to establish evidence for best practice in patients with severe CKD (creatinine clearance <30 ml/min including dialysis patients) and nonvalvular atrial fibrillation...

Atrial fibrillation is a very common arrhythmia whose prevalence is expected to increase significantly as the population ages. The associated stroke risk is a major cause of morbidity and mortality. Stroke prevention by anticoagulation carries its own risks, leading to the search for alternative strategies. Multiple techniques have been developed to exclude the left atrial appendage (the main source of thromboembolism in atrial fibrillation) from the circulation. Such techniques offer the hope of stroke prevention without the risks of anticoagulation...
