  1. 6. Fat contamination of pericardial suction blood in cardiac surgery : clinical and experimental studies in perspectives of transfusion logistics

    Författare :Micael Appelblad; Gunnar Engström; Krister Lindmark; Anders Jeppsson; Umeå universitet; []
    Nyckelord :Surgery; blood transfusion; cardiopulmonary bypass; pericardial suction blood; fat contamination; lipid microemboli; density separation; surface adsorption; Kirurgi; Surgery; kirurgi;

    Sammanfattning : Introduction: During cardiac surgery aided by cardiopulmonary bypass (CPB) the autotransfusion of pericardial suction blood (PSB) is regarded mandatory to limit allogeneic blood exposure. PSB is however proposed as a source of lipid microemboli and to contribute to brain damage. LÄS MER

  3. 7. Clinical and experimental insights into the use of mechanical chest compressions during prolonged resuscitation in the coronary catheterization laboratory

    Författare :Henrik Wagner; Kardiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac arrest; mechanical chest compressions; PCI; survival; coronary artery blood flow; epinephrine;

    Sammanfattning : INTRODUCTION. Prolonged cardiopulmonary resuscitation (CPR) with manual chest compressions (CC) during simultaneous percutaneous coronary intervention (PCI) is exceedingly difficult, with high mortality rates. The use of a mechanical CC (MCC) device can overcome the ordeal of manual CC. LÄS MER

  4. 8. Endothelial function and dysfunction in coronary artery bypass grafting

    Författare :Ulf Lockowandt; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :CABG; Endothelin; Endothelin-blockers; endothelium; lactate; off-pump CABG; prostacyclin; radial artery; unstable angina pectoris;

    Sammanfattning : The integrity of the endothelium is of importance for short- and long-term results following coronary artery bypass grafting (CABG). In this thesis different factors of the endothelial role in the regulation of vascular tone in relation to various current aspects of CABG have been investigated. LÄS MER

  5. 9. T Cells and NK Cells in Coronary Artery Disease : Longitudinal and methodological studies in humans

    Författare :Karin Backteman; Jan Ernerudh; Lena Jonasson; Joachim Lundahl; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Coronary artery disease (CAD) is the leading cause of death worldwide and most often due to atherosclerosis. Atherosclerosis is a chronic inflammatory process that involves the arteries, inclouding those that supply blood to the heart muscle. LÄS MER

  7. 10. Inflammation and matrix degrading proteases in coronary artery disease

    Författare :Ann Samnegård; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Myocardial infarction; matrix metalloproteinases; inflammation; polymorphism; haplotype; gender; cytokines;

    Sammanfattning : Coronary artery disease (CAD) is a major cause of morbidity and death in the world today. The underlying process, atherosclerosis, is caused by lipid accumulation and inflammatory processes within the intimal layer of the vessel wall. LÄS MER
