  1. 16. Myocardial ischemia-reperfusion and cardioprotection. A study with microdialysis in a porcine model

    Författare :Carsten Metzsch; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; heart preservation; metoprolol; levosimendan; beta-blockers; pharmacological preconditioning; myocardial ischemia; cardioprotection; glycerol; microdialysis; cold cardioplegic storage;

    Sammanfattning : The studies in this thesis are based on questions raised in the clinical setting. Perioperative myocardial ischemia occurs more often than recognized. This may lead to myocardial infarction, increased morbidity, mortality, and health care costs. LÄS MER

  3. 17. T-vector and T-loop morphology analysis of ventricular repolarization in ischemic heart disease

    Författare :Aigars Rubulis; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Sudden cardiac death (SCD) is responsible for about half of all cardiovascular deaths in the western world. Heterogeneous ventricular repolarization (VR) is a common denominator in the genesis of malignant ventricular arrhythmias responsible for SCD and the presence of coronary artery disease (CAD) is an aggravating factor.

  4. 18. Porcine myocardial ischemia-reperfusion studies on cardioprotection, ventricular arrhythmia and electrophysiology

    Författare :Jacob Odenstedt; Göteborgs universitet; []
    Nyckelord :porcine; myocardial ischemia; ventricular arrhythmia; sudden cardiac death; electrophysiology; vectorcardiography; endocardial mapping; spinal cord stimulation;

    Sammanfattning : Background: Coronary artery disease is the primary cause of death in adults in the industrialised world and ventricular fibrillation associated with myocardial ischemia is the main cause of sudden cardiac death. Restoration of blood flow and preservation of myocardial integrity throughout ischemia and reperfusion is essential to improve clinical outcome. LÄS MER

  5. 19. Respiratory and cardiovascular responses to diesel exhaust exposure

    Författare :Håkan Törnqvist; Joel Kaufman; Umeå universitet; []
    Nyckelord :lungmedicin; Lung Medicine;

    Sammanfattning : Background: Exposure to traffic-derived air pollution is associated to high incidence of respiratory and cardio-vascular morbidity and mortality. Diesel engines and fossil fuel contribute to a great amount to the ambient particulate matter pollution. 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.
