  2. 16. Fetal Cardiac Function and Venous Circulation - Experiences with Velocity Vector Imaging

    Author : Charlotte Dahlbäck; Urogynekologi och reproduktionsfarmakologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pregnancy; fetus; strain; speckle tracking; cardiac function; umbilical vein; venous; ductus venosus; Doppler;

    Abstract : Placental dysfunction resulting in intrauterine growth restriction (IUGR) is a common complication of pregnany and severe IUGR, with ensuing fetal hypoxia is an important cause of perinatal mortality and morbidity. Doppler studies of fetal and maternal vessels are routinely used for fetal surveillance and alterations in fetal venous blood flow has been demonstrated as a late sign of fetal compromise. READ MORE

  4. 17. Epidemiology of venous thromboembolism with focus on risk markers

    Author : Magdalena Johansson; Lars Johansson; Marcus Lind; Jan-Håkan Jansson; Gerd Lärfars; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Venous thromboembolism; venous thrombosis; deep vein thrombosis; pulmonary embolism; incidence; risk markers; diabetes; glucose; alcohol consumption; alcohol dependence; physical activity; medicin; Medicine;

    Abstract : Background: Venous thromboembolism (VTE) is a vascular disease with an incidence of approximately 140 cases per 100,000 person-years in adults. The incidence of VTE has increased over the last decades, and more than 20% of affected individuals die in the first year after diagnosis. READ MORE

  5. 18. Stroke prevention in atrial fibrillation

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

    Abstract : 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. READ MORE

  6. 19. Epicardial ablation - a study evaluating thoracoscopic and surgical ablation procedures for patients with intractable atrial fibrillation

    Author : Johan Probst; Carina Blomström-Lundqvist; Rasmus Borgquist; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; atrial fibrillation; epicardial ablation; surgical ablation; quality of life; pulmonary vein isolation; mitral valve surgery; concomitant surgery; Cardiology; Kardiologi;

    Abstract : Atrial fibrillation (AF) is a common condition, increasing in prevalence with age. Symptoms can be severe and quality of life is affected in patients suffering from AF. Treatment regimes aim to alleviate symptoms through rate or rhythm control. READ MORE

  7. 20. 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

    Author : Panagiotis Arvanitis; Carina Blomström-Lundqvist; Mårten Rosenqvist; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE
