  1. 1. Detection of myocardial ischemia : clinical and experimental studies with focus on vectorcardiography, heart rate and perioperative conditions

    Författare :Sören Häggmark; Ulf Näslund; Michael F Haney; Mårten Rosenqvist; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology and intensive care; myocardial ischemia; pacing; vectorcardiography; electrocardiography; heart rate; myocardial lactate; Anestesiologi och intensivvård; Anaesthetics and intensive care; Anestesiologi och intensivvård; kardiologi; Cardiology;

    Sammanfattning : Introduction. Multiple clinical methods for detecting myocardial ischemia are utilised in the hospital setting each day, but there is uncertainty about their diagnostic accuracy. LÄS MER

  3. 2. Cellular monitoring in open heart surgery. Monitoring of markers for ischemia, free amino acids, glucose and lactate in the myocardial interstitial fluid before, during and after cardiac surgery using microdialysis technique

    Författare :Charles Kennergren; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cardiac surgery; myocardial ischemia; microdialysis; interstitial markers; ASAT; troponin-T; amino acids; glucose; lactate;

    Sammanfattning : Protection of the myocardium during open-heart surgery is a field of intense development. Numerous protocols have been proposed to minimize ischemia, since the beginning of open-heart surgery more than 40 years ago. LÄS MER

  4. 3. Energy-Related Metabolites during and after Induced Myocardial Ischemia and Retroperfusion of the Coronary Sinus : An Experimental Study in the Pig with the Microdialysis Technique and Extracorporeal Circulation

    Författare :Vitas Zemgulis; Rolf Ekroth; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Ischemia; myocardial infarction; reperfusion; energy metabolism; coronary sinus retroperfusion; microdialysis; taurine; nucleoside transport; adenosine; aerobic lactate production; Kirurgi; Surgery; Kirurgi; Thoracic and Cardivascular Suregery; kirurgi; särskilt thoraxkirurgi;

    Sammanfattning : In the clinical setting great efforts have been made with contradictory results to operate upon acutely myocardial ischemic patients. The reasons for the absence of unambiguous results are not well understood nor are they scientifically explored. LÄS MER

  5. 4. 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

  7. 5. 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
