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

   Författare :George Koulaouzidis; Michael Henein; Katrine Åhlström Riklund; Jan Engvall; Umeå universitet; []
   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 (..

3. 2. Survival and functional recovery following valve replacement in patients with severe aortic stenosis

   Författare :Wenhong Ding; Michael Y Henein; Eugenio Picano; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Aortic stenosis; surgical aortic valve replacement; transcatheter aortic valve implantation; survival; predictor; echocardiography; speckle tracking; ventricular function; twist; strain; Cardiology; kardiologi;

   Sammanfattning : Background: Aortic stenosis (AS) is the most common heart valve disease in Europe and North America. Age-related calcification of the valve is the commonest cause of acquired AS, especially in patients older than 70 years. LÄS MER

4. 3. Cardiovascular risk factors in aortic stenosis

   Författare :Johan Ljungberg; Stefan Söderberg; Bengt Johansson; Peter Nilsson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Valvular heart disease; aortic stenosis; bicuspid aortic valve; cardiovascular risk factors; hypertension; diabetes mellitus; smoking; hypercholesterolemia; obesity; shrunken pore; renal failure; Epidemiology; epidemiologi; Cardiology; kardiologi;

   Sammanfattning : Introduction: Aortic stenosis (AS) is the most common hemodynamic significant valvular heart disease and affects about 2% of the population. The incidence increases with age. When symptoms of the stenotic aortic valve disease eventually occur the 2-year mortality exceeds 50%. LÄS MER

5. 4. Signs of inflammation in different types of heart valve disease : The VOCIN study

   Författare :Lars Wallby; Lena Jonasson; Mats Broqvist; Mårten Rosenqvist; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heart valve dysfunction; heart valve disease; VOCIN study group; aortic valves; Gross valvular pathology; Cariology; Cariologi;

   Sammanfattning : Heart valve dysfunction is a relatively common condition in the population, whereas significant heart valve disease is more unusual. The cause of different types of heart valve disease depends on which valve is concerned. Rheumatic heart valve disease, has for a long time been considered to constitute a post-inflammatory condition. LÄS MER

7. 5. Aortic valve calcification : in vivo and ex vivo evaluation

   Författare :Mohamed Yousry; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Aortic valve calcification (AVC) or thickening is found in around one fifth of the general population between 65-75 years of age and increasingly thereafter. The process of aortic valve thickening and calcification is not only an aging (wear and tear) process of the valve leaflets. It is now considered to be closely related to atherosclerosis. LÄS MER
