Conclusion
As our cognitive training has shown beneficial effects, this intervention could be a promising method to enhance health‐related quality of life after cardiac surgery.The aim of this study was to investigate whether early postoperative cognitive training has an impact on health‐related quality of life and cognitive failures in daily living after cardiac surgery. The study was a 2‐arm, randomized, controlled, outcome‐blinded trial involving older patients undergoing elective heart valve surgery with extracorporeal circulation.
