  1. 1. Insulin resistance and cardiovascular function - Observational, translational and interventional studies

    Författare :Helena Utkovic Westergren; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Insulin resistance; microvascular function; peripheral vascular function; coronary flow reserve; prognosis; myocardial perfusion scintigram; animal model;

    Sammanfattning : Background: Microvascular disease is now recognized as an important driver for cardiovascular mortality and morbidity. Diabetic patients are known to suffer from this condition, leading to e.g. coronary ischemia as well as kidney dysfunction. LÄS MER

  3. 2. Assessment of microvascular function by use of transdermal iontophoresis : methodological aspects

    Författare :Erik Droog Tesselaar; Folke Sjöberg; Angela Shore; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Iontophoresis; Microcirculation; Laser-Doppler; Acetylcholine; Sodium nitroprusside; Pharmacodynamics; Pharmacokinetics skin; Physiology and pharmacology; Fysiologi och farmakologi;

    Sammanfattning : Assessment of the microcirculation is of major importance in understanding the physiology of the vasculature and in assessing te vascular effects of pathological conditions such as diabetes, hypertension and sepsis. Transdermal iontophoresis can be used to non‐invasively introduce vasoactive drugs into the skin. LÄS MER

  4. 3. Prognostic impact of coronary microvascular funtion in patients with ischemic heart disease

    Författare :Inger Haraldsson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; coronary microvascular function; coronary flow reserve; coronary artery disease; acute coronary syndromes; thrombus aspiration; pretreatment; SCAAR; SWEDHEART;

    Sammanfattning : Background: Ischemic heart disease is the leading cause of death globally. Despite recent advances in interventional and medical therapies, survivors of myocardial infarction are at high risk of recurrent cardiovascular events. LÄS MER

  5. 4. Laser Doppler Perfusion Monitoring and Imaging especially as regards testing for sympathetic nerve function

    Författare :Carolin Freccero; Kirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology; wavelength; sympathetic vasodilatation; sympathetic vasoconstriction; sympathetic nerve function; parasympathetic nerve function; laser Doppler perfusion imaging; laser Doppler perfusion monitoring; finger skin blood flow; fibre separation; contralateral cooling; Concentration; Fysiologi; Cardiovascular system; Kardiovaskulära systemet; Diagnostik; Diagnostics;

    Sammanfattning : The operating principle of all laser Doppler methods is based on the fact that incident photons shift in wavelength when interacting with moving blood cells passing through the microvascular network. After photodetection and further signal processing, the recorded parameter can be considered an arbitrary measure of tissue blood flow, and this is referred to as ?perfusion?. LÄS MER

  7. 5. A New Model for Assessment of Change in Visual Function in Diabetes

    Författare :Karl-Johan Hellgren; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diabetic retinopathy; visual function; perimetry;

    Sammanfattning : The purpose of this thesis was to determine whether perimetry using a new model to interpret deterioration or improvement in the visual field can be employed to assess change in visual function over time in diabetes. Diabetic retinopathy has long been considered a microvascular disease, but it is still a matter of debate to what extent diabetes also affects retinal neurons. LÄS MER
