  1. 1. Quantitative cardiac 15O-water PET : Assessment of left-ventricular function, remodeling, and impact of patient motion

    Författare :Jonny Nordström; Mark Lubberink; Jens Sörensen; Hendrik J Harms; Stephan Nekolla; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; positron emission tomography PET ; 15O-water; myocardial blood flow; cardiac remodeling; patient motion;

    Sammanfattning : International guidelines advocate the use of noninvasive cardiac imaging as the initial diagnostic test for coronary artery disease, the global leading cause of death according to the world health organization. Within the wide spectrum of cardiac imaging, 15O-water PET is the gold standard for noninvasive quantification of myocardial blood flow (MBF). LÄS MER

  3. 2. Mitral Valve Surgery: Effects on Cardiac Reverse Remodeling, Hemodynamics, and Clinical Outcome

    Författare :Snejana Hyllen; Thoraxkirurgi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cardiac function; mitral regurgitation; myocardial remodeling; mitral valve repair;

    Sammanfattning : Normalization of life expectancy after mitral valve surgery is highly dependent on early diagnosis and referral for surgical treatment. Among cases treated surgically, the majority (60–70%) have a degenerative etiology, which is also easiest to repair. LÄS MER

  4. 3. Pump Physiology in the Remodeled Heart

    Författare :Björn Östenson; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac magnetic resonance; cardiac remodeling; exercise imaging; exercise physiology; regional contributions to stroke volume; feature-tracking strain; atrioventricular plane displacement; atrioventricular coupling; ventricular-arterial coupling; clinical physiology;

    Sammanfattning : This thesis aimed to increase the understanding of pump physiology in the remodeled heart compared to normal pump physiology.Study I was a cross-sectional observatory study investigating the regional contributions to stroke volume in patients with heart failure prior to cardiac resynchronization therapy (CRT) and tested the hypothesis that this characterization of pumping could predict CRT response.

  5. 4. Cardiorespiratory function of euryhaline teleosts - Regulatory mechanisms, effects of warming and costs of osmoregulation

    Författare :Daniel Morgenroth; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; salinity; temperature; cardiac; vascular; gastrointestinal; acclimation; growth;

    Sammanfattning : Teleost fishes have colonized almost every aquatic habitat on earth and exhibit adaptations that allow them to thrive in environments with very diverse physico-chemical properties. One fundamental environmental variable in aquatic ecosystems is salinity, as most fish species are only able to tolerate a narrow range of salinities. LÄS MER

  7. 5. Filamin A in Cardiovascular Remodeling

    Författare :Sashidar Bandaru; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Filamin A; Cardiovascular remodelling;

    Sammanfattning : Filamin A (FLNA) is a large actin-binding cytoskeletal protein that stabilizes actin networks and integrates them with cell membranes. FLNA is therefore important for cell motility and organ development. LÄS MER
