  1. 6. A minimally invasive axial blood flow pump : an experimental and clinical study

    Författare :Urban Lönn; Howard Frazier; Linköpings universitet; []
    Nyckelord :Axial blood flow pump; Hemopump; LVAD; Beating heart CABG; MEDICINE; MEDICIN;

    Sammanfattning : The first aim of this thesis was to evaluate a new minimally invasive axial blood flow pump for treatment of patients needing circulatory support after open heart surgery. This system, the Hemopump temporary cardiac assist device, is a very small catheter mounted intracorporeal pump, which is introduced transvalvularly into the left ventricle. LÄS MER

  3. 7. Hemodynamics, echocardiography, and biomarkers in different heart failure phenotypes

    Författare :Emil Najjar; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background. Heart failure (HF) is a major health problem affecting millions of patients worldwide and is associated with impaired quality of life and poor prognosis. Different approaches including invasive and non-invasive methods can be used to provide information about the cardiac performance in HF patients. LÄS MER

  4. 8. The role of the thromboinflammatory response under hemolytic conditions : pathophysiological mechanisms and therapeutic inhibition

    Författare :Alexandra Gerogianni; Per H. Nilsson; Camilla Mohlin; Tom Eirik Mollnes; Kristina Nilsson Ekdahl; Mihály Józsi; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hemolysis; heme; thromboinflammation; biomaterials; complement inhibition; LVAD; IONPs; Biomedical Sciences; Biomedicinsk vetenskap; Immunologi; Immunology;

    Sammanfattning : In blood circulation, the complement and the coagulation cascades, together with platelets and endothelial cells form a complex network of crosstalk. When dysregulated, these interactions can lead to inflammation in combination with thrombosis (thromboinflammation) and the manifestation of pathophysiological complications. LÄS MER

  5. 9. Heart failure : advanced treatments and novel hormonal responses

    Författare :Stanislava Zabarovskaja; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Heart failure (HF) affects 2-3% of the Western population and is associated with a 1 year mortality of 20%. Despite therapeutic advances over the last decades, numerous unanswered questions remain regarding the impact of currently established therapies as well as potential new targets for therapy. Aims to investigate: 1. LÄS MER
