1. Development of a thin, soft, single segment conductance catheter for monitoring left ventricular pressure and volume
Sammanfattning : Knowledge of the leftventricular (LV) pressure-volume relation, along withparameters derived from this relation, have led to newpossibilities for the characterisation of cardiac pumpfunction, in both experimental studies and clinicalsettings.The pressure-volume diagram is apowerful tool for visualising LV performance, but in order tobe clinically useful it is necessary to make plots continuouslyand on-line.

2. Assessment of Left Ventricular Function and Hemodynamics Using Three-dimensional Echocardiography
Sammanfattning : Left ventricular (LV) volumes and ejection fraction (EF) are important predictors of cardiac morbidity and mortality. LV volumes provide valuable prognostic information which isparticularly useful in the selection of therapy or determination of the optimal time for surgery. LÄS MER
3. Nitrates and Left Ventricular Dysfunction
Sammanfattning : Use of beta-blockers and inhibitors of the renin angiotensin system (RAS) is established practice in the treatment of chronic heart failure (CHF). Clinical studies also suggest beneficial long-term effects of nitrates in CHF. LÄS MER
4. Left Ventricular Dynamics During Exercise in Endurance Athletes
Sammanfattning : Large quantities of data have described left ventricular adaptation to endurance training, but basic concepts on left ventricular performance during exercise remain controversial. In this thesis, we present the results of studies of left ventricular dynamics during exercise in 89 endurance-trained athletes. LÄS MER
5. Insights into left atrial response to pressure and volume overload
Sammanfattning : The general purpose of this thesis is to establish the ability of Speckle Tracking Echocardiography (STE) in assessing left atrial (LA) response to pressure and volume overload respectively in aortic stenosis (AS) and mitral regurgitation (MR), and to evaluate its accuracy in predicting LA and right ventricular (RV) fibrosis in patients with end-stage heart failure (HF) undergoing heart transplantation (HTx).I demonstrated that assessment of left ventricular (LV) long axis systolic velocity and amplitude of excursion is more sensitive than simple determination of ejection fraction (EF) for revealing the beneficial impact of MR surgery on overall LV systolic performance.
