1. Negative Pressure Wound Therapy - Effects on Sternotomy Wounds and the Intrathoracic Organs
Sammanfattning : Negative pressure wound therapy (NPWT) has been widely adopted for the treatment of deep sternal wound infections due to its excellent clinical outcome. However, the mechanisms of action and effects on hemodynamics have not been thoroughly elucidated. LÄS MER
2. Variability of blood pressure and heart rate in borderline and mild hypertension : With special reference to spectral analysis
Sammanfattning : The aim of this thesis was to study whether blood pressure (BP) or heart rate (HR) variability in borderline (BHT) and hypertensive (HT) subjects differs from that in normotensive (NT) subjects, and whether indices for BP and HR variability can be used in risk stratification for future hypertension. The study groups consisted of 35 NT, 29 BHT, and 34 HT middle-aged men. LÄS MER
3. Aspects on Cardiac Pumping
Sammanfattning : Cardiac pumping physiology is important for understanding the pathophysiology of patients with cardiac disease. MRI gives the opportunity to measure volumes and flow non-invasively with high accuracy and precision. This thesis examines some aspects on cardiac pumping physiology. LÄS MER
4. Studies on adipose tissue, body fat, body water and energy expenditure during the first four months of infancy using magnetic resonance imaging, skinfold measurements and the doubly labelled water method
Sammanfattning : During recent years much interest has been focused on the relationship between early nutrition and the future health of humans. Poor growth during early life has been associated with impaired glucose tolerance and coronary heart disease later in life, while rapid weight gain in infancy has been associated with an increased risk of obesity during childhood.

5. Cardiovascular structure and function in obesity. The impact of body composition, sleep apnea and sustained weight loss
Sammanfattning : Background: Obesity is associated with disturbances in cardiovascular structure and function varying along with the degree of fatness, but the mechanisms underlying this co-variation are unclear. Short-term weight loss appears to have favourable effects on the cardiovascular system, but whether such improvements are maintained in the long run is unknown. LÄS MER
