  1. 1. Investigation of the origin of the coronary artery calcification process and its relationship to the atherosclerotic cardiovascular disease

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :George Koulaouzidis; Umeå universitet.; [2013]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Coronary artery calcification; ethnicity; South Asians; Caucasians; reproducibility; aortic valve calcification; mitral valve calcification; family history of coronary artery disease; natural history; coronary artery calcium score; meta-analysis;

    Sammanfattning : The objectives of this thesis are: a) To examine racial/ethnic differences in coronary artery calcification (CAC) and CAD, between symptomatic South Asians and Caucasians, matched for age, gender and conventional cardiovascular risk factors, b) To assess, using a meta-analysis model, the natural history of and stability of measurements of coronary artery calcium scoring (CACs) based on data collected from two large published trials: St Francis and EBEAT, c) To investigate the prevalence of coronary artery calcification in individuals with CT evidence for AVC, mitral valve calcification (MAC) or of both of them (AVC+MAC), d) To assess any potential association between premature CAD (<55 years in first-degree male relatives and <65 years in first-degree female relatives) and CAC in a large cohort of asymptomatic individuals.We found that coronary artery calcification is more extensive and diffuse in symptomatic patients of South Asian ethnic origin as compared to Caucasians, despite similar conventional risk factors for CAD.

  2. 2. Molecular mechanisms of cardiovascular calcification

    Detta är en avhandling från Stockholm : Karolinska Institutet, Dept of Medicine, Solna

    Författare :Miguel Carracedo Ortiz; Karolinska Institutet.; Karolinska Institutet.; [2019]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Cardiovascular calcification is a pathophysiological process characterized by the deposition of calcium-phosphate crystals in the arteries and the leaflets of the heart valves. In the arteries calcification causes arterial stiffness, which may lead to poor cardiac perfusion, systolic hypertension and heart failure. LÄS MER

  3. 3. Carotid artery disease plaque features and vulnerability

    Detta är en avhandling från Umeå : Umeå University

    Författare :Fisnik Jashari; Umeå universitet.; [2015]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Carotid atherosclerosis; ultrasound; plaque features; echogenicity; calcification; surface plaque irregularities; subclinical atherosclerosis; cerebrovascular symptoms; Cardiology; kardiologi; cardiovascular disease; hjärt- och kärlforskning;

    Sammanfattning : Background: Atherosclerosis is an important cause of stroke. Ultrasound offers the convenience of real-time and detailed assessment of carotid plaque features as well as arterial wall thickening and composition. LÄS MER

  4. 4. Carotid calcifications in panoramic radiographs in relation to carotid stenosis

    Detta är en avhandling från Umeå : Umeå University

    Författare :Maria Garoff; Umeå universitet.; [2016]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; carotid stenosis; panoramic radiography; calcification; atherosclerosis; odontologi; Odontology;

    Sammanfattning : Calcifications in carotid atheromas can be detected in a panoramic radiograph (PR) of the jaws. A carotid artery calcification (CAC) can indicate presence of significant (≥ 50%) carotid stenosis (SCS). LÄS MER

  5. 5. Giant cell arteritis. Epidemiological, morphological and molecular genetic studies

    Detta är en avhandling från Göteborg

    Författare :Vigdís Pétursdóttir; Göteborgs universitet.; Gothenburg University.; [2000]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Giant cell arteritis; temporal artery; aorta; epidemiology; atrophy; calcification; estrogen receptor a; morphometry; immunocytochemistry; Western blot; molecular genetics;

    Sammanfattning : Giant cell arteritis (GCA) is a chronic inflammatory disorder of unknown etiology, affecting large and medium-sized arteries, predominantly in postmenopausal women. Its pathogenesis is probably multifactorial. Several studies suggest that GCA is an antigen-driven disease. LÄS MER
