  1. 1. Multidimensional MRI  of Myocardial Dynamics : Acquisition, Reconstruction and Visualization

    Författare :Andreas Sigfridsson; Hans Knutsson; Sebastian Kozerke; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MRI; Cardiac motion; myocardial dynamics; strain; tensor; deformation; DENSE; k-t BLAST; Medical engineering; Medicinsk teknik;

    Sammanfattning : Methods for measuring deformation and motion of the human heart in-vivo are crucial in the assessment of cardiac function. Applications ranging from basic physiological research, through early detection of disease to follow-up studies, all rely on the quality of the measurements of heart dynamics. LÄS MER

  3. 2. Cardiac lipid storage and metabolism following myocardial ischemia

    Författare :Christina Drevinge; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lipid accumulation; Myocardial Ischemia; Lipid droplets; Perilipin2; Perilipin5;

    Sammanfattning : Myocardial ischemia is associated with cellular- and metabolic adjustments within the heart, including accumulation of lipids. Myocardial lipids are stored in cytosolic droplets, consisting of a core of neutral lipids surrounded by a complex surface containing proteins, such as perilipins. LÄS MER

  4. 3. Inflammation, platelet aggregation and prognosis in acute myocardial infarction

    Författare :Angelo Modica; Thomas Mooe; Håkan Wallén; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Myocardial infarction; C-reactive protein; platelet aggregation; prognosis; Cardiology; Kardiologi; Medicine; medicin;

    Sammanfattning : The incidence of stroke and re-infarction is noticeably high in the first few days following acute myocardial infarction. This finding has raised questions whether the systemic inflammatory reaction secondary to myocardial necrosis is involved. LÄS MER

  5. 4. On the dynamic ST-segment during acute myocardial infarction

    Författare :Per Johanson; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acute myocardial infarction; ST-monitoring; prognosis; angiography;

    Sammanfattning : Acute myocardial infarction is the single most common cause of death for both men and women in Sweden. Great efforts have over the years successfully been made to improve immediate treatment and care, and thereby prognosis. However, inadequacies in use of new knowledge and technology have been reported in this field. LÄS MER

  7. 5. Annular dynamics of the human heart : novel echocardiographic approaches to assess ventricular function

    Författare :Carljohan Carlhäll; Neil B. Ingels Jr.; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    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.
