Off-hours effect: does time of day or day of week influence mortality in patients with acute myocardial infarction?

摘要

Systems of care have been implemented across the world to improve access to and timeliness of reperfusion therapy for patients with ST-elevation myocardial infarction (STEMI) [l]. Recent advances include developing regional networks and using prehospital electrocardiograms to activate the cardiac catheteriza-tion lab team [2,3]. For patients with non-STEMI (NSTEMI), standardized protocols for medications and early angiography have been implemented [4]. Within this context, what are the remaining vulnerable patients and systems of care for patients with STEMI and NSTEMI?
