Show more The objective of this dissertation was to establish the value of QCT to further enhance the clinical applicability and accuracy of coronary CTA. The automatic characterization of coronary atherosclerosis with QCT is feasible and correlates well with IVUS VH. Secondly, novel CTA risk score was created incorporating detailed information on the location, severity and composition of atherosclerosis as assessed with QCT. This CTA risk score allows accurate risk stratification of patients with suspected CAD. A drawback of coronary CTA is the fact that the hemodynamic significance of a lesion cannot be evaluated. In this thesis it was demonstrated that QCT provided better correlation with the presence of myocardial ischemia on SPECT MPI as compared to current visual assessment of coronary CTA. With regards to the specific setting of high risk diabetic patients without chest pain syndrome several conclusion can be derived from this thesis. First, if treated with optimal medical therapy, very few patients present with progression of myocardial ischemia. Second, the prognosis of these patients is good; the overall long-term event-rate is limited. Especially diabetic patients without CAD on coronary CTA have an excellent prognosis. Show less

Show moreIn dit proefschrift hebben wij de invloed van mestcellen in dierexperimentele modellen voor reumatoïde artritis en aderverkalking bestudeerd met een focus op de rol van mestcellen in de (sub)-klinische fases van het ziekteproces, waarin er een actieve immuunrespons ontwikkeld was. Ook hebben wij de aanwezigheid van verschillende soorten antistoffen in het serum van cardiovasculaire patiënten onderzocht. Wij hebben de niveaus van antilichamen gecorreleerd aan klinische observaties zoals body mass index (BMI), lipidenprofiel, klinische diagnose van vaatlijden, samenstelling van de atherosclerotische plaque en de uitkomst van de ziekte.

Show more The main objective of this thesis was to unravel relationships between obesity, insulin resistance, hyperglycemia, and atherosclerosis. It is well-established that patients with type 2 diabetes have a 2- to 3-fold increased risk of cardiovascular disease. We investigated whether insulin resistance and hyperglycemia are associated with atherosclerosis and incident cardiovascular disease before the onset of type 2 diabetes. Obesity can be considered as a common cause of both insulin resistance and atherosclerosis. Therefore, we investigated to what extent associations between insulin resistance, hyperglycemia and atherosclerosis were explained by body fat. We further aimed to study the specific role of visceral fat in the development of insulin resistance and atherosclerosis, and directly assessed abdominal subcutaneous and visceral adipose tissue depots.
