1. 11. 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. 12. Myocardial Scars on MRI : Their Prevalence and Possible Impact

   Författare :Charlotte Ebeling Barbier; Håkan Ahlström; Tomas Bjerner; Lars Johansson; Lars Lind; Kirsi Lauerma; Uppsala universitet; []
   Nyckelord :Radiology; magnetic resonance imaging; myocardial infarction; epidemiology; myocardial infarction; epidemiology; Radiologisk forskning;

   Sammanfattning : Myocardial infarction (MI) causes high morbidity and mortality worldwide and for effective prevention and treatment MIs have to be adequately detected.The existence of clinically unrecognized MIs (UMIs) has been known for the past hundred years, but an ultimate tool for their detection has not yet been found.

4. 13. Electrocardiographic Imaging of Myocardial Ischemia, Infarction and Scar: Correlation with SPECT, MRI and Arrhythmias

   Författare :David G Strauss; Lund Klinisk fysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electrocardiography; Imaging; Arrhythmias; Ischemia; Infarction; Cardiomyopathy; SPECT; MRI;

   Sammanfattning : This thesis focuses on the development and testing of electrocardiographic (ECG) methods to diagnose and characterize myocardial ischemia, infarction and fibrosis (scar). The goal is to provide improved decision support to physicians regarding the optimal selection of patients for two costly, invasive therapies – percutaneous coronary intervention (PCI) for patients with acute myocardial infarction (MI) and implantable cardioverter defibrillators (ICDs) for patients with heart failure and reduced left ventricular ejection fraction (LVEF).

5. 14. Myocardial metabolism and ischemia assessed by microdialysis. Clinical and experimental studies in cardiac surgery

   Författare :Vittorio Mantovani; Göteborgs universitet; []
   Nyckelord :microdialysis; cardiac metabolism; myocardial ischemia;

   Sammanfattning : Background: The available methods to study myocardial metabolism and ischemia show considerable limitations when employed during and after cardiac surgery. Microdialysis is a technique for continuous sampling of substances from the interstitium. LÄS MER

7. 15. Movement artifact reduction in laser Doppler blood flowmetry : myocardial perfusion applications

   Författare :MG Daniel Karlsson; Karin Wårdell; Knut Kvernebo; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Laser Doppler perfusion monitoring (LDPM) and imaging (LDPI) enable assessment of tissue microvascular perfusion. The techniques are based on the Doppler broadening of the optical spectrum occurring when coherent laser light is scattered by moving red blood cells (RBC). LÄS MER
