PURPOSE The aims of this study were to estimate the incidence of atrial fibrillation and atrial flutter (AF), to assess the presence of provoking factors and risk factors for stroke and systemic embolism, and to determine the type of AF in patients with first-diagnosed AF. PATIENTS AND METHODS This cohort study was performed in northern Sweden between January 1, 2011 and December 31, 2012. Di...

detection of stealth targets calls for employment of high-power radars which itself relies on usage of high-gain antennas like large parabolic reflectors. in the past few years, using of an array with many small reflectors instead of a large reflector antenna has been considered. this method provides enhanced eirp by a factor of n2 where n is the number of array antennas. regarding improvement ...

OBJECTIVE To identify risk factors for atrial fibrillation (AF) following lobectomy for a pulmonary malignant tumour. METHODS The outcomes of patients who underwent lobectomy from February 2005 to September 2010 were analysed with respect to the development of postoperative AF. RESULTS Among 186 patients, 20 developed AF and these had significantly higher preoperative B-type natriuretic pep...

BACKGROUND Atrial fibrillation (AF) is a common arrhythmia and a major risk factor for stroke. AIMS To assess whether AF in patients with acute ischaemic stroke is associated with severe stroke and early death. MATERIALS/METHODS Patients with acute ischaemic stroke (15,831) who were registered in the Japan Multicenter Stroke Investigators' Collaboration registry were analysed. The AF group ...

OBJECTIVE This article presents a study of postoperative atrial fibrillation (AF) and its long-term effects on mortality and heart rhythm. METHODS The study cohort consisted of 571 patients with no history of AF who underwent primary aortocoronary bypass surgery from 1999 to 2000. Postoperative AF occurred in 165/571 patients (28.9%). After a median follow-up of 6 years, questionnaires were o...

BACKGROUND Atrial fibrillation (AF) results in significant morbidity and mortality. Genome-wide association studies (GWAS) have identified genetic variants associated with AF. Whether genetic variants associated with AF are also associated with atrial structure, an intermediate phenotype for AF, has had limited investigation. We sought to investigate associations between single nucleotide polym...

Background and Purpose—Atrial fibrillation (AF) is an independent risk factor for stroke. Recent studies have demonstrated that the CHA2DS2-VASc scheme is useful for selecting patients who are truly at low risk. The goal of the present study was to compare the risk of ischemic stroke among AF patients with a CHA2DS2-VASc score of 0 (male) or 1 (female) with those without AF. Methods—The study e...

Many studies have shown a relationship between atrial fibrillation (AF) and vascular dementia. AF is a major risk factor for stroke, and stroke is the greatest risk factor for vascular dementia. However, the relationship between Alzheimer's disease (AD), the leading cause of dementia, and AF remains unclear. At least four epidemiological studies have reported AF significantly raises the risk of...

Background: Atrial Fibrillation (AF) is the most common cardiac arrhythmia and an independent risk factor for stroke among the elderly. A role for inflammation in the atrial remodeling as well as development and recurrence of AF is known. Objective: To compare IL-17A between patients with different types of AF and healthy individuals. Methods: IL-17A was measured in sera of 112 patients and 107...
