The CArdiac Imaging RegistrY Study

Particular aims include: 1. To determine the prevalence of CAD for age, gender, ethnicity relative to established risk models 2. To determine associations between CAD severity and plaque type and: 1. with traditional risk factors (arterial hypertension, diabetes, hypercholesterolemia, smoking) 2. blood markers of increased cardiovascular risk 3. To determine predictive associations of between CAD with outcome (endpoint definitions in appendix) 4. To determine the risk-benefit ratio (number of subsequent interventions, complications, radiation exposure, late onset of cancer diseases, etc).
