1. 6. Ultrasonic Quantification of Skeletal Muscle Dynamics : Feasibility and Limitations

   Författare :Frida Lindberg; Lars-Åke Brodin; Christer Grönlund; Tomas Jansson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ultrasound; skeletal muscle; intramuscular; dynamics; Tissue Doppler Imaging; Speckle Tracking; strain; quantification;

   Sammanfattning : Pain and disorders of the human skeletal muscles are one of the most common reasons for medical consultations in the western countries today and there is a great need to improve both the understanding and treatment of several different muscular conditions.Techniques describing the muscle function in vivo are often limited by either their invasiveness or lack of spatial resolution.

3. 7. Insight into Coro-Carotid atherosclerotic disease in patients with acute coronary syndrome

   Författare :Rafik B. Shenouda; Michael Y. Henein; Per Wester; Ana Djordjevic-Dikic; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acute coronary syndrome; Agatston score; Atherosclerosis; Carotid calcifications; Carotid intima media thickness; Coronary calcifications; Echocardiography; Speckle tracking echocardiography; Strain; Strain rate; Tissue Doppler Imaging.; kardiologi; Cardiology;

   Sammanfattning : Background: the arterial tree branches in different parts of human body are sharing the histological and physiological features. Atherosclerosis is a systemic arterial disease, hence is expected to affect to affect more than one arterial system with similar pathologic manifestations. LÄS MER

4. 8. The effect of pressure afterload due to aortic coarctation on left ventricular function in children

   Författare :Haki Jashari; Michael Henein; Annika Rydberg; Katarina Hanséus; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Coarctation of the aorta; congenital aortic stenosis; left ventricle; myocardial deformation imaging; speckle tracking echocardiography; longitudinal strain; aorto-septal angle; children; kardiologi; Cardiology;

   Sammanfattning : Background:Coarctation of the aorta (CoA) is a congenital heart disease which represents a narrowing of the proximal descending aorta, hence increasing pressure afterload to the left ventricle (LV). Conventional treatment of native CoA is surgical repair, however potential recurrence or other related complications e.g. LÄS MER

5. 9. Insights into the effect of myocardial revascularisation on electrical and mechanical cardiac function

   Författare :Ihab Ramzy Guirguis; Michael Y Henein; Stellan Mörner; Reidar Winter; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; myocardial infarction; natriuretic peptides; echocardiography; ventricular function; atrial function; surgical revascularisation; speckle tracking echocardiography; Cardiology; kardiologi;

   Sammanfattning : Background: Acute coronary syndrome is known for its effect on cardiac function and can lead to impaired segmental and even global myocardial function. Evidence exists that myocardial revascularisation whether pharmacological, interventional or surgical results in improvement of systolic and diastolic left ventricular (LV) function, particularly that of the long axis which represents the sub-endocardial function, known as the most sensitive layer to ischaemia.

7. 10. New ultrasonographic approaches to monitoring cardiac and vascular function

   Författare :Anna Bjällmark; Lars-Åke Brodin; Kjell Karp; KTH; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medical technology; Medicinsk teknik;

   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.
