21. Achilles tendon loading and deformation during rehabilitation and use of ankle foot orthoses
Sammanfattning : Achilles tendon rupture is a common injury which most often affects otherwise healthy individuals and which causes long periods of rehabilitation with absence from work and sport activities and frequently sequele with reduced calf muscle performance. The aim of this thesis is to improve understanding of how injury affects the function of the Achilles tendon, and to functionally evaluate different designs of ankle foot orthoses used during rehabilitation after an Achilles tendon rupture.

22. New ultrasonographic approaches to monitoring cardiac and vascular function
Sammanfattning : Atherosclerotic cardiovascular disease is the leading cause of death worldwide. To decrease mortality and morbidity in cardiovascular disease, the development of accurate, non-invasive methods for early diagnosis of atherosclerotic cardiac and vascular engagement is of considerable clinical interest.

23. Cardiac dysfunction in septic shock : Observational studies on characteristics and outcome
Sammanfattning : Background: Cardiac dysfunction is a well-known complication of sepsis, but its characteristics and consequences, especially on a longer term, remain unclear. The aim of this thesis was to study the characteristics and the implications of cardiac dysfunction for outcome in intensive care unit (ICU) patients with septic shock. LÄS MER
24. Strain echocardiography in the critically ill patient : Studies in patients with septic shock and subarachnoid haemorrhage
Sammanfattning : In this thesis, strain echocardiography by two-dimensional speckle tracking imaging (2D-STI), was used for the evaluation of left ventricular (LV) and right ventricular (RV) function in critically ill patients with septic shock and subarachnoid haemorrhage. The aims were to: 1) investigate the value of strain echocardiography for the early detection of LV and RV dysfunction not diagnosed with conventional echocardiography in severe sepsis and septic shock, 2) to study the effects of norepinephrine on RV systolic function and pulmonary haemodynamics in patients with norepinephrine-dependent septic shock 3) evaluate the use of strain echocardiography for detection of myocardial injury in patients with subarachnoid haemorrhage (SAH) and 4) study the impact of general anaesthesia and positive pressure ventilation (PPV) on RV and LV myocardial longitudinal strain.

25. Mitral Valve Surgery: Effects on Cardiac Reverse Remodeling, Hemodynamics, and Clinical Outcome
Sammanfattning : Normalization of life expectancy after mitral valve surgery is highly dependent on early diagnosis and referral for surgical treatment. Among cases treated surgically, the majority (60–70%) have a degenerative etiology, which is also easiest to repair. LÄS MER
