  1. 11. Left ventricular function's relation to load, experimental studies in a porcine model

    Författare :Roman A'roch; Michael Haney; Jan Poelaert; Lars-Åke Brodin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; heart function; preload; afterload; contractility; myocardial tissue velocity; speckle tracking; Anaesthetics and intensive care; Anestesiologi och intensivvård; Cardiology; kardiologi;

    Sammanfattning : Background: Loading conditions are recognized to influence ventricular function according to the Starling relationship for length/stretch and force.  Many modern echocardiographic parameters which have been announced as describing ventricular function and contractile status, may be confounded by uncontrolled and unmeasured load.

  3. 12. Surgical ablation for the treatment of atrial fibrillation in different patient populations : A study of clinical outcomes including rhythm, quality of life, atrial function and safety

    Författare :Louise Bagge; Carina Blomström-Lundqvist; Mårten Rosenqvist; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Atrial fibrillation; surgical ablation; quality of life; vagal denervation; ganglionated plexi; left atrial function; epicardial; minimally invasive; left atrial ablation; Cardiology; Kardiologi;

    Sammanfattning : Patients with atrial fibrillation (AF) have markedly reduced quality of life (QoL) and catheter ablation has become a useful tool in the rhythm control therapy. However, because of the poor outcome for patients with persistent AF, new surgical ablation strategies for rhythm control are emerging. LÄS MER

  4. 13. Physical activity, visceral adipose tissue, and cardiovascular disease in older adults : associations and effects

    Författare :Marcel Ballin; Peter Nordström; Johan Niklasson; Maria Hagströmer; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; physical activity; exercise; obesity; stroke; myocardial infarction; death; aging; geriatrics; epidemiology; trial; Geriatrics; geriatrik; epidemiologi; Epidemiology; kardiologi; Cardiology; Public health; folkhälsa; physiotherapy; fysioterapi;

    Sammanfattning : BACKGROUND: Cardiovascular disease (CVD) poses a substantial public health burden and is the leading cause of mortality in older adults. With the population aging rapidly, interventions aimed at improving modifiable risk factors for CVD, such as physical inactivity and visceral obesity, could play an important role in reducing its burden, provided they are proven effective.

  5. 14. Respiratory and cardiovascular effects of exposure to oxidative air pollutants

    Författare :Stefan Barath; Ellinor Ädelroth; Anders Blomberg; E David Newby; M Howard Kipen; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Air Pollution; Particulate Matter; Diesel Exhaust; Ozone; Experimental Exposure studies; Luftföroreningar; Partiklar; Disel avgaser; ozon; Experimentella exponerings studier; Internal medicine; Invärtesmedicin; lungmedicin; Lung Medicine; kardiologi; Cardiology; Environmental Science; miljövetenskap;

    Sammanfattning : Background: The negative effects of air pollution on morbidity and mortality have been known since the mid 20th century. The two most well known examples are the Meuse Valley disaster in the 1930’ies and the London black fog in December 1952. LÄS MER

  7. 15. Dietary Fatty Acids and Inflammation : Observational and Interventional Studies

    Författare :Helena Bjermo; Ulf Risérus; Tommy Cederholm; Parveen Yaqoob; Uppsala universitet; []

    Sammanfattning : Dietary fat quality influences the risk of type 2 diabetes and cardiovascular disease. A low-grade inflammation is suggested to contribute to the disease development, often accompanied by obesity. Whereas n-3 polyunsaturated fatty acids (PUFA) have been considered anti-inflammatory, n-6 PUFA have been proposed to act pro-inflammatory. LÄS MER
