  1. 1. Ultrasonic Methods for 2D Arterial Wall Movement Measurements

    Författare :Magnus Cinthio; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tissue Doppler imaging; Cardiovascular system; Diagnostik; Diagnostics; Kardiovaskulära systemet; arteries; ultrasound; shear stress; axial movement; radial movement; Arterial distension; Arterial lumen diameter; PWV; Arterial longitudinal movement; pulse-wave velocity;

    Sammanfattning : Cardiovascular diseases constitute the major cause of morbidity and mortality in the Western World. To increase our knowledge of cardiovascular diseases, it is important to find methods, preferably non-invasive ones, to study very early manifestations of vascular disease. LÄS MER

  3. 2. Development and evaluation of non-invasive ultrasonic methods for arterial characterization

    Författare :Anders Eriksson; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Instrumentation technology; TDI; Tissue Doppler imaging; Arterial characterization; Non-invasive; Flow generation; PWV; Pulse wave velocity; Mät- och instrumenteringsteknik; Ultrasound; Vascular impedance;

    Sammanfattning : As cardiovascular diseases have been the most common cause of mortality in the western world for decades, the demand for appropriate diagnostic methods is obvious. To facilitate the examination non-invasive methods are preferable since they do not require sensors within the circulation system. LÄS MER

  4. 3. Aspects on wall properties of the brachial artery in man : with special reference to SLE and insulin-dependent diabetes mellitus

    Författare :Niclas Bjarnegård; Toste Länne; Reinhard Volkmann; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Arterial wall; atherosclerotic; brachial artery BA ; type 1 diabetes; ulse wave velocity PWV ; pulse wave analysis PWA ; intima-media thickness IMT ; nitrate mediated dilatation NMD ; Diabetology; Diabetologi;

    Sammanfattning : The mechanical properties of the arterial wall are of great importance for blood pressure regulation and cardiac load. With increasing age, large arteries are affected by increased wall stiffness. LÄS MER

  5. 4. Studies on the links between white adipose tissue phenotype and the circulatory system

    Författare :Jesper Bäckdahl; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Obesity is a strong risk factor for cardiovascular disease. It is defined by an unhealthy excess of white adipose tissue (WAT). Adipose derived weight gains and losses are linked to changes in two other independent cardiovascular risk factors: hypertension, and arterial stiffness. LÄS MER

  7. 5. Very preterm birth and fetal growth restriction in adolescence - Cardiovascular and renal aspects

    Författare :Jonas Liefke; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Preterm and low birth weight; Fetal growth restriction; Magnetic resonance imaging MRI ; Cardiac function; Preterm birth; Adolescence; Kidney function; Kidney anatomy histology; Cardiovascular biomarkers; Arterial stiffness; Ambulatory blood pressure measurement; Biochemical makers;

    Sammanfattning : This thesis applied magnetic resonance imaging (MRI) to investigate to what extent very preterm birth due to early onset fetal growth restriction (FGR) impacts the cardiovascular system and kidneys in adolescence. The thesis further investigated whether FGR exacerbates the organ-specific effects of very preterm birth. LÄS MER
