  1. 6. Heart failure : role of metabolic biomarkers, ejection fraction, and sex

    Författare :Ulrika Ljung Faxén; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Heart failure (HF) is common and associated with impaired quality of life (QoL) and poor prognosis. There is a ternary classification of HF based on ejection fraction (EF): HF with preserved(HFpEF), mid-range EF(HFmrEF), and reduced EF(HFrEF). LÄS MER

  3. 7. Comprehensive assessment of device-based therapy for heart failure with reduced ejection fraction

    Författare :Benedikt Norbert Schrage; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Despite a recommendation by the European guidelines, the use of implantable cardioverter defibrillators (ICD) for the primary prevention of sudden cardiac death (SCD) in patients with heart failure with reduced ejection fraction (HFrEF) is scarce. This might be explained by a lower risk of SCD in contemporary patients with HFrEF, so that the need for primary prevention ICD use in these patients has been questioned. LÄS MER

  4. 8. Prognostication in heart failure across ejection fraction phenotypes and challenging subgroups : data from the Swedish heart failure registry

    Författare :Davide Stolfo; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: The growing prevalence of heart failure (HF) worldwide determines an increasing burden on healthcare systems. HF phenotypes differ for several patient characteristics. LÄS MER

  5. 9. Assessment of Left Ventricular Function and Hemodynamics Using Three-dimensional Echocardiography

    Författare :Kambiz Shahgaldi; Lars-Åke Brodin; Michael Haney; KTH; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Three-dimensional echocardiography; heart chambers; flow-volume loop; left ventricular ejection fraction; visualization; left ventricular stroke volume; left ventricular outflow tract; and single-heartbeat; Medical technology; Medicinsk teknik;

    Sammanfattning : Left ventricular (LV) volumes and ejection fraction (EF) are important predictors of cardiac morbidity and mortality. LV volumes provide valuable prognostic information which isparticularly useful in the selection of therapy or determination of the optimal time for surgery. LÄS MER

  7. 10. Improved heart failure care organization including studies of diagnosis, risk prediction and biomarkers in heart failure with preserved ejection fraction

    Författare :Dmitri Matan; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Heart failure (HF) is a prevalent condition with low quality of life, high morbidity and mortality, and high societal costs. HF can be divided according to left ventricular ejection fraction (EF) into HF with reduced (HFrEF) or preserved EF (HFpEF). Diagnosis of HFpEF is more complex than for HFrEF. LÄS MER
