  1. 11. Pulmonary atresia with intact ventricular septum epidemiology and outcome in children born in Sweden 1980-1999

    Författare :Britt-Marie Ekman-Joelsson; Göteborgs universitet; []
    Nyckelord :pulmonary atresia with intact ventricular septum; ventriculo coronary arterial communications; biventricular repair; univentricular palliation; myocardial perfusion; myocardial function; cardiopulmonary exercise; lung function; quality of life; mortality; outcome;

    Sammanfattning : Aims: To describe children born with pulmonary atresia with intact ventricular septum (PA-IVS) in Sweden between 1980 and 1999, the incidence and outcome of PA-IVS, to examine cardio-pulmonary outcomes in survivors and to evaluate their quality of life. Material and methods: Eighty-four subjects were identified. LÄS MER

  3. 12. Artificial neural networks classify myocardial perfusion images

    Författare :Dan Lindahl; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tomography; radiology; Clinical physics; radionuclide imaging; ischemic heart disease; computer-assisted diagnosis; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Sammanfattning : In the studies of this thesis, a method for automated classification of myocardial perfusion images was successfully developed and evaluated. The results show that the method, based on artificial neural networks, was equally good, or even better than human experts. LÄS MER

  4. 13. Levosimendan in early experimental sepsis: effects on the heart and hepatosplanchnic circulation

    Författare :Doris Cunha Goncalves; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; septic shock; myocardial oxygen consumption; myocardial dysfunction; levosimendan; endotoxin; contractility; catecholamines; calcium sensitizer; cardiotonic agents; splanchnic perfusion;

    Sammanfattning : Sepsis-related cardiovascular dysfunction associated with fluid-unresponsive tissue hypoperfusion might require inotropic treatment. This cardiovascular dysfunction seems to involve calcium desensitization and adrenergic unresponsiveness. LÄS MER

  5. 14. Coagulation Inhibition and Development of Myocardial Damage in ST-Elevation Myocardial Infarction

    Författare :Gunnar Frostfeldt; Marianne Hartford; Uppsala universitet; []
    Nyckelord :Medical sciences; myocardial infarction; fibrinolysis; lmw-heparin; coagulation; troponin-T; PET; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Medicine; medicin;

    Sammanfattning : In 101 patients with ST-elevation myocardial infarction treated with streptokinase the additional effects of lmw-heparin (dalteparin) were investigated. The prognostic value of troponin-T (TnT) was elucidated and the development of myocardial damage was investigated with Positron Emission Tomography (PET). LÄS MER

  7. 15. Methods for quantitative analysis of myocardial perfusion SPECT : validated with magnetic resonance imaging, phantom studies and expert readers

    Författare :Helen Fransson; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Segmentation; Quantification; Spline; Image registration; Cardiac image analysis; Myocardial perfusion SPECT;

    Sammanfattning : In this thesis, methods for automated analysis of myocardial perfusion single photon emission computer tomography (myocardial perfusion SPECT, MPS) images have been successfully developed and evaluated. MPS images show the perfusion of the myocardium and are used for diagnosing patients with suspected ischemic heart disease. LÄS MER
