  2. 1. Pump Physiology in the Remodeled Heart

    Author : Björn Östenson; Lund Klinisk fysiologi; []
    Keywords : 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;

    Abstract : 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.

  4. 2. Magnetic Resonance Imaging of Myocardial Deformation and Scarring in Coronary Artery Disease

    Author : Johan Kihlberg; Jan Engvall; Tino Ebbers; Anders Persson; Åse Johnsson; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Although improved treatments have reduced the rates of acute complications from myocardial infarction, sequelae such as heart failure and sudden death threaten the future wellbeing of those patients. Secondary prevention after myocardial infarction is related to cardiovascular risk factors and the effect of the infarct on left ventricular function. READ MORE

  5. 3. Noninvasive Evaluation of Myocardial Ischemia and Left Ventricular Function

    Author : Eva Maret; Jan Ohlsson; Eva Nylander; Anders Waldenström; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : The general aim of this thesis was, following the path of the ischemic cascade, to evaluate the feasibility of some new non-invasive techniques for the detection of myocardial ischemia, the extent of infarcted myocardium, and for the quantification of systolic left ventricular function.Reduced longitudinal myocardial velocity and displacement may be early signs of ischemia.

  6. 4. Strategies to improve outcome in patients with ST elevation myocardial infarction treated with primary PCI

    Author : Tim Tödt; Eva Swahn; Jan Engvall; Magnus Janzon; Stefan James; Linköpings universitet; []
    Keywords : ;

    Abstract : Background: ST elevation myocardial infarction (STEMI) caused by a ruptured atherosclerotic plaque with overlying thrombosis leads to ischemia and progressively to the death of the myocardial cells supplied by the affected coronary artery. Rapid reperfusion with primary Percutaneous Coronary Intervention (PCI) in an experienced centre is the preferred therapy for these patients. READ MORE
