2. 6. Left ventricular function's relation to load, experimental studies in a porcine model

   Author : Roman A'roch; Michael Haney; Jan Poelaert; Lars-Åke Brodin; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; heart function; preload; afterload; contractility; myocardial tissue velocity; speckle tracking; Anaesthetics and intensive care; Anestesiologi och intensivvård; Cardiology; kardiologi;

   Abstract : Background: Loading conditions are recognized to influence ventricular function according to the Starling relationship for length/stretch and force.  Many modern echocardiographic parameters which have been announced as describing ventricular function and contractile status, may be confounded by uncontrolled and unmeasured load.

4. 7. Cardiac Resynchronization Therapy - Risk Stratification and Long-Term Outcome

   Author : Christian Reitan; Kardiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac Resynchronization Therapy; heart Failure; Device therapy; long-term outcome;

   Abstract : Heart failure is a condition that will affect 2-3% of the population. Around one third of the patients have a decreased LVEF and a widened QRS complex as a sign of ventricular dyssynchrony. CRT has emerged as a treatment that reduces morbidity, mortality and improve functional status in this population. READ MORE

5. 8. Cardiac effects of prolonged exercise

   Author : Anders Sahlén; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Angiotensin-Converting Enzyme; Exercise; Natriuretic Peptides; Troponin;

   Abstract : Long-distance running is growing in popularity. While moderate exercise unquestionably gives major health benefits, the effects of extreme physical exhaustion on cardiac function have been studied less. It has previously been observed that elevated cardiac biomarkers may be observed after exercise, the significance of which is not known. READ MORE

6. 9. Physiological aspects on intracardiac blood flow

   Author : Per Arvidsson; Lund Klinisk fysiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; magnetic resonance imaging; 4D flow; physiology; cardiac development; kinetic energy; hemodynamic force; vortex ring formation;

   Abstract : Magnetic resonance imaging enables detailed in vivo study of complex flow through 3D, time-resolved phase contrast imaging (4D flow). 4D flow may reveal previously unknown aspects of the physiology of intracardiac blood flow, and possibly elucidate pathophysiological processes that have yet to manifest themselves outside the heart.
