  1. 1. Heart failure biomarker effect and influence on quality of life

    Detta är en avhandling från Linköping : Linköping University Electronic Press

    Författare :Patric Karlström; Linköpings universitet.; Linköpings universitet.; [2016]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heart failure; Biomarker; B-type natriuretic peptide; Heart failure treatment; B-type Natriuretic Peptide guided heart failure treatment; Responders; Health-related quality of life; Heart failure duration; Outcomes;

    Sammanfattning : Background and aims: Heart failure (HF) is a life threatening condition and optimal handling is necessary to reduce risk of therapy failure. The aims of this thesis were: (Paper I) to examine whether BNP (B-type natriuretic peptide)-guided HF treatment improves morbidity and mortality when compared with HF therapy implemented by a treating physician at sites experienced in managing patients with HF according to guidelines; (Paper II) to investigate how to define a responder regarding optimal cut-off level of BNP to predict death, need for hospitalisation, and worsening HF and to determine the optimal time to apply the chosen cut-off value; (Paper III) to evaluate how Health-Related Quality of Life (HR-QoL) is influenced by natriuretic peptide guiding and to study how HR-QoL is affected in responders compared to non-responders; (Paper IV) to evaluate the impact of patient age on clinical outcomes, and to evaluate the impact of duration of the HF disease on outcomes and the impact of age and HF duration on BNP concentration.

    Sammanfattning : Heart failure is a growing public health problem associated with significant morbidity and mortality. Family support positively affects outcomes for the person with heart failure while also leading to caregiver burden. Registered nurses have a key role in supporting and meeting the needs of family caregivers. LÄS MER

    Sammanfattning : Throughout the world, ships are continuously being declared as total losses and 10 to 15% of these accidents are collisions between ships. The consequences of a collision are diverse and depend on the ship type, e.g. oil outflow in the case of damaged tankers or loss of stability in damaged passenger ships. LÄS MER
