Background Several studies have suggested a variation of myocardial tolerance to
ischaemia depending on the daytime of surgery. To test this hypothesis, we conducted a …

Background The purpose of this study was to investigate the association between weekday
of surgery and survival following cardiac surgery. Methods and Results In a nationwide …

Background A recent article provided compelling evidence for a cardioprotective effect of
afternoon compared with morning operation in patients undergoing aortic valve …

OBJECTIVES Several studies have shown worse outcomes in patients operated on later in
the week. We tested this hypothesis in a large UK national audit database in elective …

Objective Ongoing debate focuses on whether patients admitted to the hospital on
weekends have higher mortality than those admitted on weekdays. Whether this apparent …

Background Time of day for surgical procedures has been a topic of considerable
controversy, with some suggesting that later operating times are associated with worse …

Background Time of day potentially impacts outcomes in cardiac surgery. Therefore, the
goal of this study was to assess whether elective aortic valve replacement surgery …

Objective Recent single-center and experimental data suggested greater adverse cardiac
events for patients undergoing aortic valve replacement (AVR) in the morning (AM) versus …

Objective The purpose of the present study was to investigate the hypothesis of a
nychthemeral variation in the tolerance to ischemia and reperfusion injury in adult cardiac …

The outcomes of cardiac surgery could be better if the procedure is performed in the
afternoon rather than in the morning. This effect seems to be transcriptionally controlled by …
