  1. 1. Infarct size and myocardial function : A methodological study

    Författare :Lene Rosendahl; Jan Engvall; Thor Edvardsen; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : The size of a myocardial infarction (MI) and the concurrent effect on left ventricular (LV) function are essential for decisions regarding patient care and treatment. Images produced with the late gadolinium enhancement (LGE) technique visualize the scar with high spatial resolution. LÄS MER

  3. 2. Acute Myocardial Infarction: The Relationship between Duration of Ischaemia and Infarct Size in Humans - Assessment by MRI and SPECT

    Författare :Erik Hedström; Lund Klinisk fysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular system; Fysiologi; Physiology; humans; cardiac troponin T; creatine kinase isoenzyme MB; delayed contrast-enhanced magnetic resonance imaging; single photon emission computed tomography; myocardial perfusion; myocardial infarct size; myocardium at risk; duration of ischaemia; Kardiovaskulära systemet;

    Sammanfattning : The effect of duration of ischaemia on final infarct size is well established in animal studies, but not fully evaluated in humans. Delayed contrast-enhanced magnetic resonance imaging (DE-MRI) can be used to distinguish between viable and non-viable myocardium and thus to quantify infarct size. LÄS MER

  4. 3. Artificial neural networks for assessment of patients with suspected acutemyocardial infarction

    Författare :Johan Ellenius; Uppsala universitet; []
    Nyckelord :Medical sciences; Artificial neural network; decision-support systems; transferability; acute myocardial infarction; infarct size; nondiagnostic ECG; myoglobin; CK-MB; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; medicinsk informatik; medicinsk informatik;

    Sammanfattning : An early diagnosis within the first hours after onset of symptoms is essential for the optimal treatment of patients admitted with chest pain of suspected cardiac origin. In the majority of patients, the 12-lead ECG is nondiagnostic on admission. LÄS MER

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

    Författare :Michael Ringborn; Kardiologi; []
    Nyckelord :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.;

    Sammanfattning : 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. LÄS MER

  7. 5. Effects of postconditioning in ST-elevation myocardial infarction : assessment of myocardium at risk and infarct size

    Författare :Peder Sörensson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Myocardial infarction remains a major health problem, despite recent improvements in detection and treatment. Infarct size is a major determinant of future mortality and morbidity. LÄS MER
