NCT03774004

Brief Summary

The study is a prospective-observational, explorative single-centre cohort study aimed to examine the influence of the peripheral atherosclerotic plaque volume on short and long term morbidity and mortality in patient after coronary artery bypass grafting (CABG). Atherosclerotic disease (IMT, plaque volume) will be measured with a ultrasound system (IMT measurements and 3D quantitative plaque volumetric). Hemodynamic and flow profiles of the internal thoracic arteries will be evaluated additionally with US. These parameters will be measured pre-CABG. Morbidity will be evaluated using quality of life questionnaires (EQ-5D-3L, IPAQ). Major adverse cardiovascular events (MACE) will be the primary endpoint. The atherosclerotic burden will be compared with established risk scores (EuroSCORE, STS-Score, SYNTAX Score, FORECAST.
