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

2. Pregnancy in women with congenital heart disease
Sammanfattning : Abstract Background: The survival for children born with congenital heart disease (CHD) has increased and the majority reach adult age. Having a cardiac problem raise questions on the probability of successful pregnancies and predictors associated with unfavorable outcome. LÄS MER
3. Stem cells in the adult heart - 3D culture, isolation of side population cells and search for a stem cell niche
Sammanfattning : Cardiac tissue shows a poor regenerative capacity. From 2003 reports, mostly based on animal models, have showed existence of stem cells also in the heart. Using 14C measurements, a slow but steady turnover of the cardiac cells was shown in humans, around 1%/year. As a source for this regeneration endogenous stem cells have been suggested. LÄS MER
4. Identification of pathophysiological and prognostic biomarkers in different types of myocardial infarction
Sammanfattning : The pathophysiological mechanisms of myocardial infarction (MI) with non-obstructive coronary arteries (MINOCA) are largely unknown. Analogous, differences in pathobiology between ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI) are incompletely understood. LÄS MER
5. Diastolic heart function in hypertension-induced left ventricular hypertrophy
Sammanfattning : Hypertensive left ventricular (LV) hypertrophy is an independent strong risk factor for cardiovascular morbidity and mortality. An abnormal diastolic relaxation in the absence of systolic impairment is often seen in patients with hypertension, whether LV hypertrophy is present or not. LÄS MER
