1. 21. Prenatal Tisse Velocity Imaging of the Heart : A new approach to assess fetal myocardial function

   Författare :Nina Elmstedt; Lars-Åke Brodin; Britta Lind; Karel Marsal; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : The general aim of this thesis has been to evaluate color‐coded tissue velocity imaging (TVI) as an approach to developing a new, non‐invasive assessment method for fetal myocardial function. Such a method could hypothetically give early indications of fetal pathology, as myocardial dysfunction is often the consequence when the circulation tries to adapt to deteriorating situations.

3. 22. Evaluation of Myocardial Function in Chronic Kidney Disease : A Colour Tissue Velocity Imaging Study

   Författare :Shirley Hayashi; Lars-Åke Brodin; Svend Aakhus; KTH; []
   Nyckelord :Cardiac; Kidney; Tissue; Velocity; MEDICINE; MEDICIN;

   Sammanfattning : In patients with chronic kidney disease (CKD), overhydration, uremic toxins and left ventricular (LV) dyssynchrony are factors that may lead to LV dysfunction and conduction abnormalities and thus contribute to the high cardiac mortality. Colour tissue velocity imaging (TVI) allows a detailed quantitative analysis of cardiac function in CKD patients, opening new possibilities to evaluate longitudinal myocardial motion, rapid isovolumetric events, LV filling pressure and LV synchronicity.

4. 23. Noninvasive Evaluation of Myocardial Ischemia and Left Ventricular Function

   Författare :Eva Maret; Jan Ohlsson; Eva Nylander; Anders Waldenström; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : The general aim of this thesis was, following the path of the ischemic cascade, to evaluate the feasibility of some new non-invasive techniques for the detection of myocardial ischemia, the extent of infarcted myocardium, and for the quantification of systolic left ventricular function.Reduced longitudinal myocardial velocity and displacement may be early signs of ischemia.

5. 24. Endothelial function and dysfunction in coronary artery bypass grafting

   Författare :Ulf Lockowandt; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :CABG; Endothelin; Endothelin-blockers; endothelium; lactate; off-pump CABG; prostacyclin; radial artery; unstable angina pectoris;

   Sammanfattning : The integrity of the endothelium is of importance for short- and long-term results following coronary artery bypass grafting (CABG). In this thesis different factors of the endothelial role in the regulation of vascular tone in relation to various current aspects of CABG have been investigated. LÄS MER

7. 25. Age and gender differences in risk factor burden, myocardial dysfunction and cardiovascular events in relation to glucose metabolism

   Författare :Margrét Leosdottir; Internmedicin - epidemiologi; []
   Nyckelord :Age; cardiovascular disease; diabetes; echocardiography; gender; glucose; left ventricular function; Nt-proBNP; self-rated health;

   Sammanfattning : The risk of cardiovascular disease (CVD) and heart failure (HF) among individuals with diabetes is at least two times greater than in non-diabetic subjects. However, the excess risk of CVD in diabetic subjects seems to decrease with age. LÄS MER
