  1. 1. Echocardiography/Doppler for the evaluation of coronary artery function, left ventricular function and the relationship between early diastolic and systolic function

    Författare :Reidar Winter; Malmö Institutionen för kliniska vetenskaper; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; coronary flow reserve; contrast echocardiography; early diastolic downward velocity; flow propagation velocity; colour M-mode; diastolic function; Echocardiography; Doppler; Kardiovaskulära systemet; Cardiovascular system;

    Sammanfattning : Two specific areas of development in echocardiography are assessment of left ventricular (LV) diastolic function and myocardial ischemia. This thesis describes echocardiographic methodology in these two areas. LÄS MER

  3. 2. Effects of physical exercise on coronary and peripheral vascular function. An integrative physiological study from rat to man

    Författare :Ulrika Hägg Samuelsson; Göteborgs universitet; []
    Nyckelord :exercise; endothelial function; coronary flow velocity reserve; colour Doppler echocardiography; oxidative stress; gene expression; stiffness; ultrasound biomicroscopy;

    Sammanfattning : Physical exercise is beneficial for the cardiovascular health. Numerous epidemiological studies reveal that physical activity reduces the risk of cardiovascular related death. Nevertheless, the underlying vessel wall specific physiological and molecular mechanisms still remain incompletely understood. LÄS MER

  4. 3. Between the Probe and the Pump : An experimental study on cardiac performance analysis based on Echocardiography, tissue and laser Doppler

    Författare :Laila Hübbert; Birgitta Janerot-Sjöberg; Ulf Dahlström; Sven-Erik Ricksten; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Echocardiography is an ultrasound-based bedside, non-invasive and easily available cardiac diagnostic technique visualising the heart’s morphology and function. Quantification of cardiac wall motion can be measured with the tissue Doppler Imaging (TDI) modality which provides in humans a high diagnostic capacity to differentiate healthy from diseased myocardium with reduced function.

  5. 4. Noninvasive haemodynamic evaluation of aortic valve prostheses : Doppler echocardiographic studies at rest and during exercise

    Författare :Maria J Eriksson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :heart valve prosthesis; aortic valve replacement; Doppler echocardiography; exercise; haemodynamics; valve resistance;

    Sammanfattning : The present series of investigations was designed to supply information on in vivo pressure-flow relationships and to analyse the incidence of regurgitation in different heart valve prostheses in the aortic position. Patients and methods: The study population comprised 185 patients with mechanical Björk-Shiley Monostrut prostheses, 54 patients with Biocor stented porcine bioprostheses, 50 patients with extended Biocor stentless bioprostheses and 59 patients with cryopreserved aortic homografts.
