Popis: Background: AHA/ACC/ESC practice guidelines advise an ECG within 10 minutes for all patients with symptoms suggestive of ST-segment elevation myocardial infarction (STEMI). This facilitates early diagnosis and timely treatment. Earlier treatment, particularly percutaneous coronary intervention (PCI), has been associated with better clinical outcomes. Our objective was to quantify the impact of delayed screening on timely treatment and determine if there may be race, sex or presenting complaint disparities. Methods: We examined the association between time-to-first ECG (door-to-screening, or D2S) and time-to-PCI in a 3-center 1-year retrospective cohort study including all emergency department (ED) patients with acute STEMI per hospital discharge diagnosis who underwent catheterization for PCI. The primary outcome was door-to-balloon time (D2B) and the ED-centric secondary outcome was door-to-cath-lab arrival time (D2CAR). Results: Of 161,920 patients seen in the 3 EDs, 137 (0.08%) were diagnosed with STEMI. Of the 137, 75 (55%) underwent emergent PCI, and 31 (41%) of the ED STEMI PCI patients did not receive an ECG within 10 minutes. These 31 patients were more commonly female (55% vs. 19%, p=0.001), non-white (87% vs. 65%, p =0.028), and reported chest pain or shortness of breath less frequently (55% vs. 94%, p Conclusion: A significant proportion of ED patients with STEMI did not receive an ECG within 10 minutes of arrival resulting in a 2.2 fold increase in D2B time. They were more likely to be female, non-white, and with atypical chief complaints. Normalizing screening criteria for presentation diversity could improve more equitable access to timely STEMI treatment
