  1. 16. Quantitative echocardiographic methods for patients with acute coronary syndrome

    Författare :Carl Westholm; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Tissue Doppler;

    Sammanfattning : Background: The aim of this thesis was to evaluate two diagnostic and two prognostic quantitative echocardiographic methods for patients with acute coronary syndrome (ACS). Methods:
Velocity tracking (VeT) presents the longitudinal tissue Doppler velocities of the left ventricle (LV) as a bull’s eye plot giving an easy three dimensional understanding of both the global and regional function of the LV in regard to longitudinal velocities, systolic as well as diastolic. LÄS MER

  3. 17. Ultrasonic Methods for 2D Arterial Wall Movement Measurements

    Författare :Magnus Cinthio; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tissue Doppler imaging; Cardiovascular system; Diagnostik; Diagnostics; Kardiovaskulära systemet; arteries; ultrasound; shear stress; axial movement; radial movement; Arterial distension; Arterial lumen diameter; PWV; Arterial longitudinal movement; pulse-wave velocity;

    Sammanfattning : Cardiovascular diseases constitute the major cause of morbidity and mortality in the Western World. To increase our knowledge of cardiovascular diseases, it is important to find methods, preferably non-invasive ones, to study very early manifestations of vascular disease. LÄS MER

  4. 18. The right ventricle in volume or pressure overload : Insights from novel imaging techniques

    Författare :Aleksandra Trzebiatowska-Krzynska; Eva Swahn; Niels Erik Nielsen; Lars Wallby; Marcus Carlsson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : This study is inspired by the gap in knowledge regarding the timing of cardiac surgery and interventions in adult patients with congenital heart disease. There are many parameters used assessing right ventricular function; however, most of them have pitfalls. LÄS MER

  5. 19. 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

  7. 20. Regulation of Microvascular Blood Flow : a clinical and experimental study based on laser Doppler perfusion imaging

    Författare :Helena Golster; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Local blood flow reflexes in the foot skin of healthy controls and in young diabetic patients with or without nerve dysfunction have been studied using laser Doppler perfusion imaging (LDPI). A neurophysiological follow-up study on nerve dysfunction is presented as a complerhent to the work on blood flow regulation in the young diabetics. LÄS MER
