  1. 6. Left Ventricular Dynamics During Exercise in Endurance Athletes

    Författare :Milena Sundstedt; Tommy Jonason; Egil Henriksen; Eva Nylander; Uppsala universitet; []
    Nyckelord :Physiology; athletes; exercise; left ventricular dynamics; stroke volume; mitral annular motion; Fysiologi;

    Sammanfattning : Large quantities of data have described left ventricular adaptation to endurance training, but basic concepts on left ventricular performance during exercise remain controversial. In this thesis, we present the results of studies of left ventricular dynamics during exercise in 89 endurance-trained athletes. LÄS MER

  3. 7. 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. 8. Right heart function in health and disease : a doppler echocardiography and doppler tissue imaging study

    Författare :Per Lindqvist; Elsadig E Kazzam; Anders Waldenström; Lars Åke Brodin; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Echocardiography; Doppler tissue imaging; right ventricle; cardiac catheterisation; isovolumic relaxation; isovolumic contraction; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; kardiologi; Cardiology;

    Sammanfattning : Background: It is well known that performance of the right ventricle (RV) determines exercise capacity and may confer prognostic information in different cardiopulmonary diseases. To allow optimal patient management, ideal methods to assess right heart function are therefore important. LÄS MER

  5. 9. Detection of Myocardial Ischemia using Real-Time Myocardial Contrast Echocardiography

    Författare :Petri Gudmundsson; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; myocardial contrast echocardiography; MCE; stress echocardiography; adenosine; perfusion; real-time; visual; quantative; wall motion; power modulation; bedside; SPECT; coronary insufficiency;

    Sammanfattning : Diagnostisering av syrebrist i hjärtmuskeln med hjälp av kontrastförstärkt ultraljudsundersökning av hjärtmuskelns genomblödning. Ultraljudsundersökning av hjärtat (ekokardiografi) används mycket inom hjärtsjukvården idag, oftast för att utreda hjärtats och hjärtklaffarnas anatomi och funktion. LÄS MER

  7. 10. Atrial function and loading conditions in athletes

    Författare :Flavio D'Ascenzi; Michael Henein; Sergio Mondillo; Roxy Senior; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; athlete s heart; training; exercise; speckle-tracking echocardiography; atrial strain; atrial deformation; Cardiology; kardiologi;

    Sammanfattning : Intensive training is associated with hemodynamic changes that typically induce an enlargement of cardiac chamber. Despite LA dilatation in athletes has been interpreted as a benign adaptation, little evidence is available. LÄS MER
