  1. 6. Metabolic risk markers and relative survival in patients with aortic stenosis requiring surgery

    Författare :Anders Holmgren; Ulf Näslund; Stefan Söderberg; Michael Henein; Rune Haaverstad; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; aortic stenosis; aortic valve surgery; coronary artery disease; prospective cohort study; risk markers; lipoprotein a ; apolipoproteins; proteomics; troponin T; C-reactive protein; relative survival; observed survival; kardiologi; Cardiology;

    Sammanfattning : Background: Aortic stenosis (AS) is the most common valve disorder requiring surgery in developed countries. The etiology of AS is only partly known.  Identification of new biomarkers in prospective studies could lead to novel insights in the etiology of AS, and possibly lead to improved clinical management.

  3. 7. Automatic segmentation in CMR - Development and validation of algorithms for left ventricular function, myocardium at risk and myocardial infarction

    Författare :Jane Tufvesson; Lund Klinisk fysiologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic segmentation; cardiovascular magnetic resonance; validation; Expectation Maximization; freely available software; myocardial infarction;

    Sammanfattning : In this thesis four new algorithms are presented for automatic segmentation in cardiovascular magnetic resonance (CMR); automatic segmentation of the left ventricle, myocardial infarction, and myocardium at risk in two different image types. All four algorithms were implemented in freely available software for image analysis and were validated against reference delineations with a low bias and high regional agreement. LÄS MER

  4. 8. The role of endothelin during myocardial ischaemia and reperfusion : pathophysiological mechanisms and interactions with nitric oxide

    Författare :Adrian T Gonon; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :ischaemia; reperfusion injury; myocardium; infarct size; endothelium; endothelin; endothelin receptor; nitric oxide; nitric oxide synthase; polymorphonuclear leukocytes; myeloperoxidase; pig; rat;

    Sammanfattning : Acute myocardial infarction followed by reperfusion results in accelerated necrosis of irreversibly injured myocytes as well as induction of lethal injury to reversibly injured cells. Polymorphonuclear leukocytes (PMNs) are major participants in the reperfusion-initiated inflammation. LÄS MER

  5. 9. Early Cardiovascular Changes of Familial Hypertrophic Cardiomyopathy in the Young

    Författare :Eva Fernlund; Lund Pediatrik; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; A-ECG. SCD.; advanced ECG; CMR; Tissue Doppler; Echocardiography; Microcirculation; LaserDoppler; Athletes heart; HCM; hypertrophic cardiomyopathy; Familial hypertrophic cardiomyopathy;

    Sammanfattning : Familial hypertrophic cardiomyopathy (HCM) is the most common inherited heart disease, transmitted in an autosomal dominant fashion, i.e. 50% risk for transmission of the disease-causing mutation to each child of the affected family. LÄS MER

  7. 10. Left ventricular hypertrophy and the insulin resistance syndrome

    Författare :Johan Sundström; Uppsala universitet; []
    Nyckelord :Medical sciences; Left ventricular hypertrophy; insulin; glucose; lipids; mortality; MEDICIN OCH VÅRD; MEDICINE; MEDICIN; Geriatrics; geriatrik;

    Sammanfattning : Left ventricular hypertrophy (LVH) and the insulin resistance syndrome are common conditions associated with a markedly increased cardiovascular risk. In a fairly large prospective longitudinal study of men from the general population, we found that an unfavorable serum fatty acid profile and components of the insulin resistance syndrome such as dyslipidemia, obesity and hypertension at age 50 predicted the prevalence of LVH at age 70.
