XCT and CPBT are predictors of immediate postoperative morbidity and mortality. In our experience, cardiac procedures with CPBT<240 min and XCT<150 min were associated with a rather low risk of immediate postoperative adverse events independently of the complexity of surgery patient's operative risk.

Preoperatively older and sicker patients with complicated postoperative course are at higher risk of developing delirium after CABG. Preoperative status and operative complications together with delirium may exert negative influence on forthcoming HRQoL, which is seen especially in patients with a relatively high preoperative level of HRQoL.

We conclude that myocardial lipid peroxidation, estimated as MDA formation, is common during intermittent ischemia-reperfusion sequences in coronary bypass surgery, although some patients may be better protected. Xanthine oxidase appears to be operative in human myocardium, and free radicals generated in this reaction might also be involved in the observed lipid peroxidation process. Increased degradation of myocardial adenine nucleotides and concomitant lipid peroxidation may play a specific role in the development of reperfusion injury. In this study, however, more extensive lipid peroxidation was not associated with impaired functional recovery.
