  1. 31. The role of leptin in endothelial dysfunction and cardiovascular disease

    Författare :Manuel Cruz Gonzalez Garcia; Stefan Söderberg; Jan Engvall; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; leptin; obesity; endothelial dysfunction; cardiovascular disease; kardiologi; Cardiology;

    Sammanfattning : Objective:  Obesity has become the leading cause of mortality worldwide; however, the fundamental pathophysiology underlying this association remains unclear. The discovery of adipokines, i.e., cytokines produced by adipose cells (adipocytes), revealed that adipose tissue is a highly endocrine organ, thus opening new lines of investigation. LÄS MER

  3. 32. Invasive treatment of coronary artery disease : Aspects on antithrombotic and percutaneous treatment options

    Författare :Per Grimfjärd; Stefan James; Christoph Varenhorst; P Hedberg; Lene Holmvang; Uppsala universitet; []
    Nyckelord :PCI; STEMI; stent thrombosis; bivalirudin; heparin; bioresorbable scaffold; cangrelor; drug eluting stent; DES; Cardiology; Kardiologi;

    Sammanfattning : The outcome after percutaneous coronary intervention (PCI) has improved considerably thanks to more effective antithrombotic treatment strategies and improved coronary stents. Stent thrombosis (ST) is a rare complication to PCI associated with considerable mortality and morbidity. LÄS MER

  4. 33. Polymer-shelled Ultrasound Contrast Agents : Characterization and Application

    Författare :Dmitry Grishenkov; Leif Kari; Lars-Åke Brodin; Michel Versluis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ultrasound; contrast agents; microbubbles; polymer; perfusion; Acoustics; Akustik; Material physics with surface physics; Materialfysik med ytfysik; Cardiovascular medicine; Kardiovaskulär medicin; Cardiology; Kardiologi;

    Sammanfattning : Ultrasound-based imaging technique is probably the most used approach for rapid investigationand monitoring of anatomical and physiological conditions of internal organs and tissues.Ultrasound-based techniques do not require the use of ionizing radiation making the tests anexceptionally safe and painless.

  5. 34. Ventricular rotation and the rotation axis : a new concept in cardiac function

    Författare :Ulf Gustafsson; Anders Waldenström; Per Lindqvist; Alan Fraser; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Left ventricular function; right ventricular function; rotation; twist; rotation axis; transition plane; ischemia; speckle tracking echocardiography; Cardiology; Kardiologi; Cardiology; kardiologi;

    Sammanfattning : Background: The twisting motion of the left ventricle (LV), with clockwise rotation at the base and counter clockwise rotation at the apex during systole, is a vital part of LV function. Even though LV rotation has been studied for decades, the rotation pattern has not been described in detail. LÄS MER

  7. 35. From Stenting to Preventing : Invasive and Long-term Treatment for Coronary Artery Disease in Sweden

    Författare :Kristina Hambræus; Bertil Lindahl; Bo Lagerqvist; Eva Prescott; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Coronary artery disease; guideline adherence; prevention; cholesterol treatment; lifestyle; percutaneous coronary intervention; Cardiology; Kardiologi;

    Sammanfattning : Coronary artery disease (CAD) is the leading cause of death worldwide. Treatment with coronary interventions, long-term treatment and life style changes can reduce symptoms and improve prognosis. LÄS MER
