Postoperative delirium (POD) and postoperative cognitive decline (POCD) can be observed after cardiosurgical interventions. Taken together, these postoperative neurocognitive dysfunctions contribute to increased morbidity and mortality and higher economic costs. Preoperative risk factors of postoperative neurocognitive dysfunctions, such as decreased neuropsychometric performance or decreased cognitive daily activities, can be interpreted as reduced cognitive reserve. The aim of this study is to build up cognitive reserves to protect against the development of POD and POCD through preoperative, home-based, cognitive training.

Number of participants with postoperative cognitive decline at 3 months after surgery, defined as a decrease between pre- and postoperative examinations of one standard deviation in at least 20% of all objective neuropsychological parameters
Timeframe: Immediately pre-training to 3 month post-surgery
Number of participants with postoperative cognitive decline at the time of discharge from the acute clinic, defined as a decrease between the pre- and postoperative examinations of one standard deviation measured with the "Montreal Cognitive Assessment"
Timeframe: Immediately pre-training to approximately 1 week post-surgery
Number of participants with postoperative delirium during the stay in the intensive care unit as assessed using the "Intensive Care Delirium Screening Checklist" (ICDSC)
Timeframe: Immediately post-surgery to approximately 1-2 days post-surgery
Number of participants with postoperative delirium during the stay on normal ward as assessed using the "Confusion Assessment Method" (3D-CAM)
Timeframe: Approximately 1 week (Immediately post-intensive care unit to approximately 1 week post-intensive care unit)
