2. 1. Methodological aspects of quantitative cardiac molecular imaging

   Author : Tanja Kero; Mark Lubberink; Håkan Ahlström; Elin Trägårdh; Uppsala universitet; []
   Keywords : PET; cardiac amyloidosis; 11C-PIB; retention index; standardized uptake value; PET-MR; MRI; myocardial blood flow; 15O-water; quantification; quantitative modeling;

   Abstract : The objective of this research was to facilitate the use of quantitative cardiac molecular imaging by developing and validating methods and applications. More specifically:we determined the optimal tracer kinetic model for analysis of 11C-PIB and evaluated the performance of two simpler measures, retention index (RI) and standardized uptake value (SUV), in the quantification of cardiac 11C-PIB uptake in amyloidosis.

4. 2. Strain echocardiography in cardiac surgery - studies on the effects of loading conditions and inotropic agents on myocardial contraction and relaxation

   Author : Martin Fredholm; Göteborgs universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; strain echocardiography; right heart catheterization; cardiac surgery; heart failure; levosimendan; milrinone; left ventricular function; right ventricular function; systole; diastole; preload; afterload; pacing; longitudinal function; ventricular dimensions; ventricular interdependence;

   Abstract : Background: Although reductions in myocardial contractility and relaxation are key compo-nents in heart failure (HF), assessment of them is difficult, as clinical measurements deal with a net effect of myocardial contractility, heart filling (preload), outflow impedance (afterload) and heart rate (HR). Echocardiographic (echo) deformation parameters, like strain (myocardial shortening) and strain rate (the speed of deformation, SR), have been proposed to more accu-rately measure myocardial function, but incongruent previous studies have raised concerns that they may be load-dependent.

5. 3. Exercise physiology and cardiac function. Aspects on determinants of maximal oxygen uptake

   Author : Katarina Steding Ehrenborg; Lund Klinisk fysiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; respiratory indices; peak oxygen uptake; heart failure; cardiac magnetic resonance imaging; exercise physiology;

   Abstract : Although the athlete's heart has been of interest for over 100 years, further characterization of the athletes heart is needed in order to understand how training affects cardiac dimensions and function. Few studies have investigated the effects of training in female athletes and few have compared males and females. READ MORE

6. 4. Exercise-Based Cardiac Rehabilitation in Patients with Coronary Artery Disease : Attendance, Adherence and the Added Value of a Behavioural Medicine Intervention

   Author : Sabina Borg; Maria Bäck; Birgitta Öberg; Lennart Nilsson; Joep Perk; Linköpings universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Abstract : Background: Coronary artery disease (CAD) is the leading global cause of death. After an index event related to CAD, exercise-based cardiac rehabilitation (exCR) is strongly recommended as part of the secondary prevention. READ MORE

7. 5. The oesophageal route in clinical electrocardiology

   Author : Steen Pehrson; Kardiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiovascular system; oesophageal electrocardiogram; cardiac pacing; Transoesophageal stimulation; arrhythmias; non-invasive electrophysiology; atrial fibrillation; supraventricular tachycardia; Kardiovaskulära systemet;

   Abstract : The subject of this thesis is the clinical use of the oesophageal electrode in electrocardiology. The three areas covered are oesophageal electro- cardiography, the biophysics of transoesophageal atrial stimulation (TAS) and the clinical utility of TAS. The literature is reviewed with respect to these areas. READ MORE
