Add to ORKGThe aim of this thesis is to evaluate fast-track cardiac anesthesia techniques and investigate their impact on postoperative mortality, morbidity and quality of life. The following topics will be discussed in the thesis. (1.) Is fast track cardiac anesthesia a safe technique for cardiac surgery? (2.) Does thoracic epidural anesthesia have an effect on mortality and morbidity after cardiac surgery? (3.) Does thoracic epidural anesthesia have an effect on quality of life after cardiac surgery? (4.) Do we need thoracic epidural anesthesia as a component of fast track cardiac anesthesia? (5.) What is quality of life after cardiac surgery? (6.) What are the risk factors for poor quality of life after cardiac surgery
