2. 1. Psychological distress in coronary heart disease : Risk indicators, treatment and cardiovascular prognosis

   Author : Fredrika Norlund; Claes Held; Erik Olsson; Petra Lindfors; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; psychological distress; myocardial infarction; coronary heart disease; depression; anxiety; stress; cognitive behavioral therapy; iCBT; stress management; cardiac rehabilitation; Psychology; Psykologi;

   Abstract : The aims of this thesis were to: (1) explore factors associated with emotional distress; (2) investigate psychosocial stress as a risk factor for cardiovascular (CV) morbidity in patients with coronary heart disease (CHD); (3) investigate the impact of group-based stress management on psychological outcomes, and if that mediates risk of CV events; and (4) evaluate an internet-based cognitive behavioral therapy (iCBT) for emotional distress in patients with a recent myocardial infarction (MI).In Study I, data from the national registry SWEDEHEART on 27,267 MI patients < 75 years was used.

4. 2. Cardiovascular modelling and ultrasound heart flow quantification : aortic flow and mitral regurgitation

   Author : Lars E. J. Eidenvall; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : The primary objective of this thesis was to model and simulate aortic flow and mitral regurgitation and to improve quantitative ultrasound measurements. The tools used were; theoretical analysis, computer simulation, model experiments, image analysis and clinical evaluation. READ MORE

5. 3. Modelling and Quality Assessment of Atrial Fibrillatory Waves

   Author : Mikael Henriksson; Avdelningen för Biomedicinsk teknik; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ECG; signal processing; atrial fibrillation; signal quality; catheter ablation; atrial fibrillatory waves; f-waves;

   Abstract : This doctoral thesis revolves around the analysis of electrocardiogram (ECG) signals during atrial fibrillation (AF). Special emphasis is put on the atrial fibrillatory waves, sometimes called the f-waves, which is the ECG component reflecting the electrical activity of the atria. READ MORE

6. 4. Cardiovascular and pulmonary health effects of air pollution - long term effects in Sweden and effects of wood smoke

   Author : Leo Stockfelt; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Air pollution; wood smoke; human exposure studies; dispersion modelling; cohort studies; cardiovascular disease;

   Abstract : Exposure to air pollution is associated with increased morbidity and mortality in cardiovascular and pulmonary diseases. Main suggested mechanisms are airway and systemic inflammation, affecting hemostasis in the short term and atherosclerosis in the long term. READ MORE

7. 5. Deposition and absorption of inhaled drugs

   Author : Eva Bondesson; Malmö Klinisk fysiologi och nuklearmedicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; tomografi; radiologi; Klinisk fysiologi; medical instrumentation; tomography; radiology; Clinical physics; technetium-99m; radionuclide imaging; radioactive aerosol; powder inhaler; pharmacokinetics; mucociliary clearance; lung deposition; gamma scintigraphy; inhalation; deposition modelling; drug absorption; absorption enhancer; aerosol; medicinsk instrumentering; Physiology; Fysiologi;

   Abstract : Main objectives of this thesis were to evaluate a gamma scintigraphic method used to quantify drug aerosol deposition in the lung, to investigate the influence of two aerosol inhalation parameters on the distribution of inhaled dry powder within the airways, to assess pulmonary absorption kinetics and bioavailability of an inhaled hydrophilic solute in relation to site of deposition, and to assess the influence of a surface active agent (sodium taurocholate, a bile salt) on the deposition and absorption of an inhaled hydrophilic solute. Repeated planar gamma scintigraphy was found to provide the same information on total pulmonary drug deposition as an independent method that involved assessments of urinary drug recovery after blockage of gastrointestinal drug absorption when all of the critical parts of the methodological procedures were accurately and meticulously executed.
