1. 11. Electrical remodeling in arial fibrillation - assessment using surface electrocardiograms, prognostic implications and potential reversal

   Författare :Andreas Bollmann; Kardiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; atrial fibrillation; electrocardiography; stroke; biomarkers;

   Sammanfattning : The fibrillatory rate of the surface ECG during atrial fibrillation (AF) has been suggested for quantification of the individual atrial remodeling, to monitor interventions and to predict the response to different therapies. In this dissertation, the relation between fibrillatory rate of the surface ECG and (1) clinical and echocardiographic variables, (2) the outcome of cardioversion, (3) circulating markers of inflammation and hemostasis, (4) the risk of left atrial thrombus formation, (5) the risk of stroke, and (6) the effects of candesartan on the fibrillatory rate were investigated in human persistent atrial fibrillation (AF).

3. 12. Atrial fibrillation – on its trigger mechanisms, risks and consequences

   Författare :Dritan Poci; Göteborgs universitet; []
   Nyckelord :acute coronary syndromes; atrial fibrillation; AV junctional ablation; CHADS2 score; electrical cardioversion; mortality; stroke; trigger mechanisms;

   Sammanfattning : Background: Atrial fibrillation (AF) frequently impairs quality of life, but in long-term it is associated with an increased morbidity and mortality. Persistent AF may cause changes in the sinus node function, and if converted to sinus rhythm (SR), there is a substantial risk of recurrence of AF. LÄS MER

4. 13. 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

5. 14. Impacts of Active Transport on Health : with a focus on physical activity, air pollution, and cardiovascular disease

   Författare :Wasif Raza; Johan Nilsson Sommar; Bertil Forsberg; Benno Krachler; Otto Hänninen; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Health impact assessment; Air pollution; Active commuting; Exercise; Interaction. Cardiovascular diseases; Ischemic heart diseases; Stroke; Public health; folkhälsa; Occupational and Environmental Medicine; arbets- och miljömedicin;

   Sammanfattning : Background: There are increasing number of health impact assessment studies investigating the health effects by transferring trips made by motorised transport to active commuting; however, air pollution exposure during active commuting and its impact on health has been less thoroughly assessed. It is furthermore uncertain whether there is any interaction effect between air pollution and physical activity for the risk of cardiovascular diseases. LÄS MER

7. 15. Stroke severity and outcome : in search of predictors using a population-based strategy

   Författare :Peter Appelros; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Stroke; incidence; epidemiology; risk factors; prognosis; outcome;

   Sammanfattning : This thesis, based on studies conducted in Örebro, the main municipality of Örebro County in Sweden, sought: 1) to determine the incidence rate and case fatality of first-ever stroke in a well-defined population; 2) to show the effects of selection bias on the frequency of different stroke characteristics; 3) to establish the incidence of neglect and anosognosia and their impact on disability; 4) to show the impact of pre-stroke risk factors on stroke severity and case fatality; and 5) to show the influence of stroke severity and other risk factor on one year mortality, on dependency after one year and on the risk of recurrent stroke. All first-ever cases of stroke were registered during a 12-month period 1999-2000. LÄS MER
