1. 1. Dysfunctional but viable myocardium - ischemic heart disease assessed by magnetic resonance imaging and single photon emission computed tomography

   Författare :Martin Ugander; Lund Klinisk fysiologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medicinsk instrumentering; tomografi; radiologi; medical instrumentation; Klinisk fysiologi; radiology; tomography; Clinical physics; non-invasive imaging; myocardial infarction; viability; Physiology; Fysiologi; Cardiovascular system; Kardiovaskulära systemet;

   Sammanfattning : The assessment of ischemic heart disease (IHD) often focuses on the detection of dysfunctional but viable myocardium which may improve in function following revascularization. Dysfunctional but viable myocardium is identified by distinct characteristics with regards to function, perfusion and viability. LÄS MER

3. 2. Imaging and modeling the cardiovascular system

   Författare :Elira Maksuti; Michael Broomé; Anna Bjällmark; Matilda Larsson; Martin Ugander; Patrick Segers; KTH; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cardiac pumping; diastolic function; hemodynamics; modeling; simulation; arterial stiffness; ultrasound; shear wave elastography.; Medical Technology; Medicinsk teknologi; Cardiac pumping;

   Sammanfattning : Understanding cardiac pumping function is crucial to guiding diagnosis, predicting outcomes of interventions, and designing medical devices that interact with the cardiovascular system.  Computer simulations of hemodynamics can show how the complex cardiovascular system is influenced by changes in single or multiple parameters and can be used to test clinical hypotheses.

4. 3. Coarctation of the aorta : register and imaging studies

   Författare :Daniel Rinnström; Bengt Johansson; Michael Henein; Martin Ugander; Gerhard-Paul Diller; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; coarctation of the aorta; adult congenital heart disease; hypertension; left ventricular hypertrophy; body mass index; height; weight; register; CMR;

   Sammanfattning : Background Coarctation of the aorta (CoA) constitutes 5-8 % of all congenital heart disease (CHD) and is associated with long-term complications such as hypertension (HTN) and left ventricular hypertrophy (LVH). Factors associated with HTN, LVH, and diffuse myocardial fibrosis, are not yet fully explored in this population. LÄS MER
