SOARES, Sónia Oliveira de Matos  and  FERREIRA, Paulo Alexandre Carvalho. Acute myocardial infarction patients in the emergency department: factors influencing door-to-treatment time. Rev. Enf. Ref. [online]. 2017, vol.serIV, n.15, pp.31-42. ISSN 0874-0283.  https://doi.org/10.12707/RIV17053.

Context: In the context of acute myocardial infarction (AMI) management, mortality and morbidity rates increase as the symptom-onset-to-balloon time increases. Objective: To analyze the door-to-treatment time (DTt) of AMI patients at the emergency department (ED) and to identify factors influencing DTt. Methodology: Retrospective, quantitative, descriptive, correlational study. The medical records of 412 people who were admitted to the ED in 2014 and 2015 were analyzed. Results: The results showed that 65% of patients had non-ST-segment elevation myocardial infarction (NSTEMI) and 35% of them had ST-segment elevation myocardial infarction (STEMI). Door-to-electrocardiogram time was on average 1h40. Of the 126 STEMI patients, 114 underwent primary percutaneous coronary intervention (PCI), with an average DTt of 7h19, and 12 underwent fibrinolysis, with an average DTt of 1h19. Conclusion: Age, smoking, absence of diabetes, type of transport, and period of admission to the ED were identified as factors influencing DTt.
