  1. 31. Quantification of left-to-right shunt through Patent Ductus Arteriosus by colour Doppler

    Författare :Solweig Harling; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : The aim of this thesis was to develop a non-invasive method to quantify the size of a shunt through a patent ductus arteriosus (PDA) by ultrasound and to test its usability in clinical settings. There is no consensus regarding the optimal management strategy for a PDA in premature infants. LÄS MER

  3. 32. Time dependency in the protection from myocardial injury after myocardial ischemia and reperfusion : new insights from experimental studies with the ultrashort-acting calcium antagonist clevidipine

    Författare :Daisuke Segawa; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Myocardial ischemia; reperfusion; calcium antagonist; clevidipine; preconditioning; experimental studies; rat; pig.;

    Sammanfattning : Interruption of the coronary blood flow causes myocardial ischemia and, after a critical time period, myocardial cell death. Accordingly, early reinstitution of arterial blood flow is necessary to minimize the damage. LÄS MER

  4. 33. On the use of computed tomography in cardiac imaging

    Författare :Jakob De Geer; Anders Persson; Jan Engvall; Michael Sandborg; Örjan Smedby; Åse Johnsson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : BackgroundCardiac Computed Tomography Angiography (CCTA) is becoming increasingly useful in the work‐up of coronary artery disease (CAD). Several potential methods for increasing the diagnostic yield of cardiac CT are available. LÄS MER

  5. 34. IL-25 and B cells in atherosclerosis

    Författare :Polyxeni Mantani; Kardiovaskulär forskning - immunitet och ateroskleros; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; IL-25; B cells; ILC2s; IL-5; anti-PC IgM; atherosclerosis; stroke; cardiovascular events;

    Sammanfattning : Atherosclerosis is a chronic inflammatory disease of medium and large vessels of the body which is mainly characterized by the formation of lipid rich plaques within the arterial tissue. It is the most common cause of cardiovascular disease leading to clinical manifestations of coronary artery and cerebrovascular disease. LÄS MER

  7. 35. Porcine myocardial ischemia-reperfusion studies on cardioprotection, ventricular arrhythmia and electrophysiology

    Författare :Jacob Odenstedt; Göteborgs universitet; []
    Nyckelord :porcine; myocardial ischemia; ventricular arrhythmia; sudden cardiac death; electrophysiology; vectorcardiography; endocardial mapping; spinal cord stimulation;

    Sammanfattning : Background: Coronary artery disease is the primary cause of death in adults in the industrialised world and ventricular fibrillation associated with myocardial ischemia is the main cause of sudden cardiac death. Restoration of blood flow and preservation of myocardial integrity throughout ischemia and reperfusion is essential to improve clinical outcome. LÄS MER
