  1. 6. Population-based studies of atrial fibrillation and ischemic stroke

    Författare :John Berntsson; Kardiovaskulär forskning - epidemiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atrial fibrillation; Ischemic stroke; Biomarker; Stroke; Natriuretic peptides; Vascular endothelial growth factor; Epidemiology; Atrial Fibrillation; Stroke; Ischemic stroke; Natriuretic peptides; Vascular endothelial growth factor; Epidemiology;

    Sammanfattning : AbstractBackground: Atrial fibrillation (AF) is a major risk factor for ischemic stroke and the most common cause of cardioembolic stroke. Early detection of AF and AF subjects at high risk for stroke is therefore important. LÄS MER

  3. 7. Clinical evaluation and implications of left atrial remodeling in atrial fibrillation : From silent cerebral lesions and atrial stunning to novel electrocardiographic tools for prediction of arrhythmia outcome

    Författare :Panagiotis Arvanitis; Carina Blomström-Lundqvist; Mårten Rosenqvist; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atrial fibrillation; left atrial remodeling; recurrence; new-onset; silent cerebral lesions; white matter hyperintensities; cardioversion; pulmonary vein isolation; risk factors; electrocardiographic predictors; P-wave indices; machine learning; predictive models; Covid-19;

    Sammanfattning : Atrial fibrillation (AF) is the most common cardiac arrhythmia. Left atrial (LA) remodeling and reverse remodeling are associated with cerebral involvement and cognitive function (CF) changes. Risk stratification for AF related outcomes is essential in the management of patients with AF. LÄS MER

  4. 8. Stroke prevention in atrial fibrillation

    Författare :Sara Själander; Peter J. Svensson; Bo Carlberg; Håkan Walfridsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atrial fibrillation; stroke; oral anticoagulation; aspirin; haemorrhage; electrical cardioversion; pulmonary vein isolation; Cardiology; kardiologi;

    Sammanfattning : Background: The Framingham Study from 1991 showed a clear correlation between atrial fibrillation (AF) and ischemic stroke, where patients with AF had an almost fivefold increase in risk of stroke compared with patients without AF. Since then, several trials have evaluated different antithrombotic treatments to reduce the risk of stroke in patients with AF. LÄS MER

  5. 9. Atrial fibrillation after cardiac surgery : an analysis of risk factors, mechanisms, and survival effects

    Författare :Giovanni Mariscalco; Bengt Åberg; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; atrial fibrillation; adult; cardiac surgery; coronary artery bypass grafting; valvular surgery; cardiopulmonary bypass; mortalilty; histology; catecholamines; embolism; Surgery; Kirurgi;

    Sammanfattning : Background: Despite the recent improvements in surgical techniques and postoperative patient care, atrial fibrillation (AF) remains the most frequent complication after cardiac surgery. Although postoperative AF is often regarded as a benign clinical condition, this arrhythmia has significant adverse effects on patient recovery and postoperative survival. LÄS MER

  7. 10. Catheter ablation for atrial fibrillation : effects on rhythm, symptoms and health-related quality of life

    Författare :Anna Björkenheim; Dritan Poçi; Deirdre Lane; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atrial fibrillation; catheter ablation; symptoms; quality of life;

    Sammanfattning : Background: AF ablation is an increasingly used treatment in patients with AF to improve patient-reported outcomes (PROs). Atrioventricular junction ablation (AVJA) is a palliative treatment option in therapy refractory AF that improves PROs but renders the patient pacemaker dependent. LÄS MER
