1. 16. Carotid Vessel Wall Thickness and Echogenicity : In the ULSAM study

   Författare :Martin Wohlin; Lars Lind; Johan Sundström; Samar Basu; Stefan Agewall; Uppsala universitet; []
   Nyckelord :Medicine; Epidemiology; Medicin;

   Sammanfattning : In this thesis the common carotid artery intima media thickness in nearly 500 elderly men is independently associated with insulin sensitivity, measured by the gold standard hyperinsulinemic euglycemic clamp test (paper 1), to both COX- and cytokine mediated inflammation independently of other markers of inflammation, oxidative stress and antioxidant status (paper 2) and also to the alleles of the apolipoprotein gene independently of lipid levels and cardiovascular risk factors (paper 3). The echogenicity of the carotid intima-media complex measured as grey scale median predicts mortality independently of common carotid artery intima-media thickness, prior cardiovascular disease and cardiovascular risk factors (paper 4).

3. 17. Boundary Detection in Cardiovascular Ultrasonic Images Based on Multiscale Dynamic Programming

   Författare :Quan Liang; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiscale dynamic programming; artery measurement; cardiac measurement; edge-preserving smoothing; ultrasonic imaging; boundary detection;

   Sammanfattning : Non-invasive ultrasonic imaging is widely used in cardiovascular studies as well as clinical diagnostics. This is due to its non-invasiveness, low cost and easy operation. However, ultrasonic images are noisy and present artifacts, speckles, and echo dropouts. LÄS MER

4. 18. Cardiovascular Risk Genes in Prevention and Treatment Response

   Författare :Viktor Hamrefors; Kardiovaskulär forskning - hypertoni; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; blood pressure treatment; hypertension; statins; dyslipidemia; cardiovascular prevention; cardiovascular genetics; stroke; coronary artery disease; chromosome 9p21; pharmacogenetics; pharmacogenomics;

   Sammanfattning : GENERAL AIM: To investigate how common single-nucleotide-polymorphisms (SNPs) that associate with cardiovascular disease (CVD) could be used in prevention and treatment of CVD. SUBJECTS: Subjects from the population-based Malmö-Diet-and-Cancer-(MDC)-Study (n=30447) and hypertensives from the Nordic-Diltiazem-(NORDIL)-Study (n=10881). LÄS MER

5. 19. Progressive stroke : clinical course and outcome

   Författare :Åsa Rödén-Jüllig; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Acute stroke; Carotid artery disease; Heparin; Progressive stroke; Outcome; Stroke assessment;

   Sammanfattning : The knowledge about progression of symptoms in acute stroke patients was scanty when this thesis was planned. The aim was therefore to study if the rate and type of progression, had any impact on patient outcome, predictors for progression and effectiveness of heparin treatment. LÄS MER

7. 20. Atherosclerosis and Insulin Resistance AIR A cross-sectional study of 58-year old men

   Författare :Lena Bokemark; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Insulin resistance; intima-media thickness; LDL particle size; atherosclerosis.;

   Sammanfattning : The main aim of the study was to test the hypothesis that insulin resistance is associated with atherosclerotic disease in the carotid and femoral arteries as measured using the ultrasound technique in clinically healthy 58-year old men with varying degrees of obesity and insulin resistance. The subjects were recruited from the general population and were free from clinical cardiovascular disease, diabetes mellitus and treatment with antihypertensive, lipid-lowering and anti-diabetic drugs (n=818).
