6. 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
7. Annular dynamics of the human heart : novel echocardiographic approaches to assess ventricular function
Sammanfattning : The complex myocardial fiber architecture of the left ventricle (LV) enables long-axis motion (annular excursion), short-axis motion and also a small torsional deformation throughout the cardiac cycle. The contribution of the long-axis motion has proven to be important in generating ventricular filling and emptying, and the analysis of annular excursion has become a well established diagnostic tool for the assessment of ventricular function.

8. Usefulness of coronary angiography for assessing left ventricular function
Sammanfattning : This thesis focus on the physiological information, on left ventricular (LV) motion in the long axis, evaluated in routine coronaty angiography sequences and based on previous knowledge from echocardiographic studies. As coronary angiography has become a very frequent examination, a method for assessment of LV function from routine coronary angiograms would probably have a significant impact on clinical work.

9. Echocardiographic methods for assessment of coronary artery disease
Sammanfattning : Upright bicycle exercise echocardiography with digital image acquisition in seated position during exercise and in recumbent position before and immediately after exercise was performed in 66 men, one month after an episode of unstable coronary arte1y disease. It was difficult to obtain images of adequate quality during exercise but new or worsening of wall motion abnormalities not seen in recumbent position after exercise were detected at peak-exercise in patients with good image quality.

10. Doppler tissue imaging in ST-elevation myocardial infarction
Sammanfattning : Highly available, noninvasive and cost-effective, echocardiography remains a keystone in the evaluation of patients with coronary artery disease (CAD). Echocardiographic assessment of cardiac function at rest and during dobutamine stress has direct clinical implications. LÄS MER
