Relationship between time of day, day of the week and in-hospital mortality in patients undergoing emergency percutaneous coronary intervention.
Previous studies have reported circadian variation in the rate of post-percutaneous coronary intervention (PCI) complications and mortality. ⋯ Our study shows a significant time-dependent effect on in-hospital deaths in patients treated with emergency PCI. Healthcare organization and circadian variation of ischaemic processes could explain this variation in mortality.
