  2. 1. Myocardial ischemia : As a risk indicator after an episode of unstable angina or non-Q-wave myocardial infarction

    Author : Hans Larsson; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : The diagnostic and prognostic value of different noninvasive tests were evaluated in men below 70 years of age admitted to the coronary care unit (CCU) with unstable coronary artery disease (CAD) i.e unstableangina or non-Q-wave myocardial infarction (Ml). A symptom limited exercise test (ET) was performed before discharge in 740 patients. READ MORE

  4. 2. Ventricular Depolarization in Ischemic Heart Disease.Value of Electrocardiography in Assessment of Severity and Extent of Acute Myocardial Ischemia

    Author : Michael Ringborn; Kardiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acute myocardial ischemia; Acute myocardial infarction; Severity of ischemia; QRS changes; HF-QRS; QRS slopes; Depolarization changes; Myocardium at risk; Final infarct size; SPECT.;

    Abstract : Background In patients with symptoms compatible with acute myocardial infarction (MI), early triage by ECG in the pre-hospital phase by ST-segment elevation myocardial infarction (STEMI) criteria is important for direct transport of these patients to a regional center for primary percutaneous coronary intervention (pPCI). The time from first medical contact to pPCI should, due to present guidelines, be no longer than two hours. READ MORE

  5. 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

    Author : Vitas Zemgulis; Rolf Ekroth; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. Myocardial ischemia and reperfusion injury, clinical and experimental studies

    Author : Karin Åström-Olsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; myocardium; ischemia; reperfusion injury; FKBP12; FKBP12.6;

    Abstract : Acute myocardial infarction is the consequence of an occluded nutrient coronary artery. Reperfusion reduces infarct size and enhances the rate of survival. But reperfusion may also, in itself, cause reversible injury, stunning and arrhythmias, as well as irreversible lethal reperfusion injury. READ MORE

  7. 5. ST-elevation myocardial infarction : studies of outcome in relation to fibrinolysis and ischemia monitoring with on-line vectorcardiography

    Author : Johan Nilsson; Ulf Näslund; Kurt Boman; Kristian Thygesen; Umeå universitet; []
    Keywords : Medicine; Myocardial infarction; vectorcardiography; fibrinolysis; reperfusion; Medicin; kardiologi; Cardiology;

    Abstract : The treatment of acute myocardial infarction (AMI) has undergone a tremendous development during the last decades, and the most important factor is probably the introduction of reperfusion therapy aimed at preventing or limiting the myocardial injury. It is of vital importance that patients with AMI are adequately monitored regarding the development of ECG changes during and after treatment to identify successful or failed reperfusion and to detect episodes of recurrent ischemia.
