  1. 11. Platelet Inhibition and Bleeding in Coronary Artery Bypass Surgery

    Författare :Ulrica Alström; Elisabeth Ståhle; Ulf Schött; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bleeding; cardiac surgery; platelet inhibition; re-exploration; cost analysis; Anaesthetics and intensive care; Anestesiologi och intensivvård; Thoraxkirurgi; Thorax Surgery; Anaesthesiology and Intensive Care; Anestesiologi och intensivvård;

    Sammanfattning : A substantial number of patients undergoing cardiac surgery are on dual anti-platelet treatment with clopidogrel and aspirin. A disadvantage with this treatment is increased risk of bleeding. Bleeding is a complication of major concern associated with adverse outcome for the patient and increased hospital resource utilization. LÄS MER

  2. 12. Thermal tolerance in teleost fish –importance of cardiac oxygen supply, ATP production and autonomic control

    Författare :Andreas Ekström; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; acclimation; coronary; CTmax; enzyme; global warming; heart; mitochondria;

    Sammanfattning : Temperature tolerance is a key determinant of the resilience and adaptability of fish facing a warmer and more thermally variable future with climate change. Yet, the underlying physiological mechanisms determining the critical thermal maximum (CTmax) are poorly understood. LÄS MER

  3. 13. Effects of physical exercise on coronary and peripheral vascular function. An integrative physiological study from rat to man

    Författare :Ulrika Hägg Samuelsson; Göteborgs universitet; []
    Nyckelord :exercise; endothelial function; coronary flow velocity reserve; colour Doppler echocardiography; oxidative stress; gene expression; stiffness; ultrasound biomicroscopy;

    Sammanfattning : Physical exercise is beneficial for the cardiovascular health. Numerous epidemiological studies reveal that physical activity reduces the risk of cardiovascular related death. Nevertheless, the underlying vessel wall specific physiological and molecular mechanisms still remain incompletely understood. LÄS MER

  4. 14. Management of patients treated with left ventricular assist devices : A clinical and experimental study

    Författare :Bengt Peterzén; Henrik Casimir-Ahn; Hans Ruthberg; Lars Wiklund; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; postcardiotomy heart failure; perioperative monitoring; coronary artery bypass; heart-assist devices; heart failure; congestive; ventricular dysfunction; Thoracic surgery; Thoraxkirurgi;

    Sammanfattning : This thesis describes the management of patients treated with mechanical circulatory support devices for short- or long-term use. Twenty-four patients suffering from postcardiotomy heart failure were treated with a minimally invasive axial flow pump. LÄS MER

  5. 15. Quantitative cardiac 15O-water PET : Assessment of left-ventricular function, remodeling, and impact of patient motion

    Författare :Jonny Nordström; Mark Lubberink; Jens Sörensen; Hendrik J Harms; Stephan Nekolla; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; positron emission tomography PET ; 15O-water; myocardial blood flow; cardiac remodeling; patient motion;

    Sammanfattning : International guidelines advocate the use of noninvasive cardiac imaging as the initial diagnostic test for coronary artery disease, the global leading cause of death according to the world health organization. Within the wide spectrum of cardiac imaging, 15O-water PET is the gold standard for noninvasive quantification of myocardial blood flow (MBF). LÄS MER
