2. 1. Cardiac hypertrophy : transcription patterns, hypertrophic progression and extracellular signalling

   Author : Nina Gennebäck; Stellan Mörner; Anders Waldenström; Urban Hellman; Ali J Marian; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac hypertrophy; HCM; gene expression; OPLS-DA; multivariate dataanalysis; cardiomyocytes; exosomes; microvesicles; Medicine; medicin;

   Abstract : 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.

4. 2. Ventricular rotation and the rotation axis : a new concept in cardiac function

   Author : Ulf Gustafsson; Anders Waldenström; Per Lindqvist; Alan Fraser; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Left ventricular function; right ventricular function; rotation; twist; rotation axis; transition plane; ischemia; speckle tracking echocardiography; Cardiology; Kardiologi; Cardiology; kardiologi;

   Abstract : Background: The twisting motion of the left ventricle (LV), with clockwise rotation at the base and counter clockwise rotation at the apex during systole, is a vital part of LV function. Even though LV rotation has been studied for decades, the rotation pattern has not been described in detail. READ MORE

5. 3. Aspects of regular long-term endurance exercise in adolescents, with focus on cardiac size and function, hormones, and the immune system

   Author : Louise Rundqvist; Maria Faresjö; Peter Blomstrand; Katarina Steding-Ehrenborg; Jönköping University; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; adolescence; endurance-trained; cardiac dimension; cardiac systolic function; cardiac diastolic function; growth hormone; immune response; echocardiography; biomarkers; cytokines; chemokines; insulin-like growth factor 1; type 1 diabetes-related autoantigen; proinsulin;

   Abstract : The long-term effects of starting high-intensity training at younger ages are largely unknown. The present studies focused on adolescents who had performed regular endurance exercise for several years at an elite level and compared those subjects with a control group of adolescents of similar age and sex who had not engaged in regular exercise.

6. 4. Lung Emphysema & Cardiac Function

   Author : Kirsten Jörgensen; Göteborgs universitet; []
   Keywords : emphysema; hemodynamics; ventricular end-diastolic volumes; lung volume reduction; ventricular function; transoesophageal echocardiography; magnetic resonance imaging; diastole; simendan; hypertrophy;

   Abstract : Patients with severe lung emphysema have poor quality of life because of impaired lung function and reduced exercise tolerance. Concomitant heart disease in severe emphysema is well recognised. The prevailing view is that mainly the right side of the heart is involved, while the issue of left ventricular (LV) involvement is less studied. READ MORE

7. 5. Aspects on Cardiac Pumping

   Author : Marcus Carlsson; Lund Klinisk fysiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac Pumping; Ventricular Function; Fysiologi; Physiology;

   Abstract : 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. READ MORE
