  1. 1. Acute Myocardial Infarction: The Relationship between Duration of Ischaemia and Infarct Size in Humans - Assessment by MRI and SPECT

    Författare :Erik Hedström; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular system; Fysiologi; Physiology; humans; cardiac troponin T; creatine kinase isoenzyme MB; delayed contrast-enhanced magnetic resonance imaging; single photon emission computed tomography; myocardial perfusion; myocardial infarct size; myocardium at risk; duration of ischaemia; Kardiovaskulära systemet;

    Sammanfattning : The effect of duration of ischaemia on final infarct size is well established in animal studies, but not fully evaluated in humans. Delayed contrast-enhanced magnetic resonance imaging (DE-MRI) can be used to distinguish between viable and non-viable myocardium and thus to quantify infarct size. LÄS MER

  3. 2. On leg ischaemia : aspects of epidemiology and diagnostics

    Författare :Björn Jönsson; Eric Wahlberg; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The first part of this thesis consists of a population-based epidemiological study on symptomatic leg arterial disease in a Swedish community, based on a postal questionnaire and systolic ankle pressure measurements, with calculation of the ankle-brachial pressure index (ABPI; usually ≥ 1.0 in healthy subjects).

  4. 3. Myocardial protection by hyperoxia

    Författare :Peeter Tähepõld; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Oxygen is essential for normal respiration in aerobic organisms, and prolonged deficit of oxygen always has detrimental consequences.However, all aerobic life forms are faced with the threat of oxidation from molecular oxygen. LÄS MER

  5. 4. Cardiac muscle injury in children and experimental animals. Reflections in ECG, especially high-resolution electrocardiography

    Författare :Rolf Bennhagen; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pediatrics; Kardiovaskulära systemet; Cardiovascular system; signal-averaging ECG; ischaemia; cardiac transplantation; Pediatri;

    Sammanfattning : Background and Methods: Signal-averaging ECG (SAECG), a bioelectrical processing method, is a further development of the conventional ECG. SAECG can detect voltage potentials in the microvolt range and provide a noise-reduced determination of QRS duration. Extended frequency spectra can be analysed. LÄS MER

  7. 5. Pharmacological interventions against myocardial ischemia and reperfusion injury

    Författare :Lars O Karlsson; Göteborgs universitet; []
    Nyckelord :Myocardial reperfusion injury; opioids; cyclosporine A;

    Sammanfattning : Background: Ischaemic heart disease is the leading cause of death in the industrialised world. Although the concept of early restoration of coronary blood-flow constitutes an important factor to reduce the injury caused by myocardial ischaemia, reperfusion in itself can aggravate the damage to myocardial tissue, a phenomenon denoted myocardial reperfusion injury.
