  4. 4. 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.
