Review Meta Analysis
Off-hour presentation and outcomes in patients with acute myocardial infarction: systematic review and meta-analysis.
To assess the association between off-hour (weekends and nights) presentation, door to balloon times, and mortality in patients with acute myocardial infarction. ⋯ This systematic review suggests that patients with acute myocardial infarction presenting during off-hours have higher mortality, and patients with STEMI have longer door to balloon times. Clinical performance measures may need to account for differences arising from time of presentation to a healthcare facility.
