  1. 16. Myocardial metabolism in experimental infarction and heart failure

    Författare :Truls Råmunddal; Göteborgs universitet; []
    Nyckelord :Myocardial metabolism; Heart failure; Myocardial infarction; Lipotoxic heart disease; Apolipoprotein B; Arrhythmias; Cardiac reserve; Creatine metabolism;

    Sammanfattning : Abstract The heart is an organ heavily dependent on exogenous lipids for the oxidative production of adenosine-triphosphate (ATP) and therefore maintenance of normal cellular energy homeostasis. However, high energy flux organs such as the heart must closely match lipid import and utilization or otherwise lipids will accumulate in the cardiomyocytes. LÄS MER

  3. 17. Pharmacological interventions against myocardial ischemia and reperfusion injury

    Författare :Lars O Karlsson; Göteborgs universitet; []
    Nyckelord :Myocardial reperfusion injury; opioids; cyclosporine A;

    Sammanfattning : Background: Ischaemic heart disease is the leading cause of death in the industrialised world. Although the concept of early restoration of coronary blood-flow constitutes an important factor to reduce the injury caused by myocardial ischaemia, reperfusion in itself can aggravate the damage to myocardial tissue, a phenomenon denoted myocardial reperfusion injury.

  4. 18. Clinically Unrecognized Myocardial Scars Detected by MRI

    Författare :Raquel Espregueira Themudo; Tomas Bjerner; Andrew Arai; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; unrecognized myocardial scars; myocardial infarction; epidemiology; magnetic resonance; computed topographic coronary angiography; exercise test; NT-proBNP; Radiology; Radiologi; Cardiology; Kardiologi;

    Sammanfattning : A high percentage of unrecognized myocardial infarctions (UMIs) seen at delayed-enhanced magnetic resonance imaging (DE-MRI) are not detected by ECG. DE-MRI-detected UMIs are independent predictors of cardiovascular events in patients with coronary artery disease. LÄS MER

  5. 19. Glutamate for metabolic intervention in coronary surgery : with special reference to the GLUTAMICS-trial

    Författare :Mårten Vidlund; Rolf Svedjeholm; Torbjörn Ivert; Örebro universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; myocardial ischemia; coronary artery bypass; cardiac surgery; acute coronary syndrome; glutamate; metabolic intervention; postoperative heart failure; myocardial recovery; Surgery; Kirurgi;

    Sammanfattning : Myocardial ischemia is a major cause of postoperative heart failure and adverse outcome in coronary artery bypass graft surgery (CABG). Conventional treatment of postoperative heart failure with inotropic drugs may aggravate underlying ischemic injury. LÄS MER

  7. 20. High-Frequency ECG in Ischemic Heart Disease

    Författare :Jonas Pettersson; Avdelningen för klinisk genetik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiology; Clinical physics; high-frequency QRS components; electrocardiogram; myocardial infarction; myocardial ischemia; Ischemic heart disease; tomography; medical instrumentation; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering;

    Sammanfattning : Analysis of high-frequency QRS components (HF-QRS) is one of the emerging methods for increasing the diagnostic performance of the electrocardiogram (ECG). The overall objective of the thesis is to investigate whether analysis of HF-QRS has the ability to provide information about ischemic heart disease and so serve as an adjunctive diagnostic tool in several clinical situations.
