  5. 4. Stable high-sensitivity cardiac troponin T levels and outcomes

    Författare :Andreas Roos; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Many patients who seek medical attention because of chest pain in the emergency department (ED), without myocardial infarction (MI) as a final diagnosis, will have cardiac troponin (cTn) levels above the upper normal limit when measured with the high-sensitivity cardiac troponin T (hs-cTnT) assay. In patients with acute medical diseases other than MI which may affect hs-cTn levels, treatment strategies focus on underlying conditions. LÄS MER
