1. Cardiac hypertrophy : transcription patterns, hypertrophic progression and extracellular signalling
Sammanfattning : Background: The aim of this thesis was to study transcription patterns and extracellular signalling of the hypertrophic heart to better understand the mechanisms initiating, controlling and maintaining cardiac hypertrophy.Cardiac hypertrophy is a risk factor for cardiovascular morbidity and mortality.

2. Evaluation of Myocardial Function in Chronic Kidney Disease : A Colour Tissue Velocity Imaging Study
Sammanfattning : In patients with chronic kidney disease (CKD), overhydration, uremic toxins and left ventricular (LV) dyssynchrony are factors that may lead to LV dysfunction and conduction abnormalities and thus contribute to the high cardiac mortality. Colour tissue velocity imaging (TVI) allows a detailed quantitative analysis of cardiac function in CKD patients, opening new possibilities to evaluate longitudinal myocardial motion, rapid isovolumetric events, LV filling pressure and LV synchronicity.

Sammanfattning : The brain-derived protein S100B is a 21 Kda dimerand have been used as a serum marker for brain damage of different etiology. The feasability of protein S100B as serum marker for brain damage after cardiac surgery was studied in this thesis. One unexpected finding was made, which changed the basis for interpration of S100B levels. LÄS MER
Sammanfattning : The overall aims of this thesis were to elucidate the circulatory responses to ultra-endurance exercise (Adventure Racing), and furthermore, to contribute to the clarification of the so called “exercise-induced cardiac fatigue” in relation to said exercise. An Adventure race (AR) varies in duration from six hours to over six days, in which the participants have to navigate through a number of check-points over a pre-set course, using a combination of three or more endurance/outdoor sports, e.

5. Quantitative cardiac 15O-water PET : Assessment of left-ventricular function, remodeling, and impact of patient motion
Sammanfattning : International guidelines advocate the use of noninvasive cardiac imaging as the initial diagnostic test for coronary artery disease, the global leading cause of death according to the world health organization. Within the wide spectrum of cardiac imaging, 15O-water PET is the gold standard for noninvasive quantification of myocardial blood flow (MBF). LÄS MER
