  •   Objective  To analyze the features of door to balloon (DTB) dilation time and its time points in patients with acute ST segment elevation myocardial infarction (STEMI) by emergency percutaneous coronary intervention (PCI).
      Methods  Data of DTB and its time points (emergency retention time, transit time and intervention time) in 180 STEMI patients with emergency PCI from January 2018 to December 2020 were collected. According to different standards, patients were divided into standard DTB group and non-standard DTB group, working time group and non-working time group, self-paid group and non-self-paid group, and 2018 group and 2020 group. The related indexes were compared between groups.
      Results  Average DTB of 180 STEMI patients was (115.0±51.9) min; the emergency retention time was (71.4±50.3) min, in which door to Cardiology Department response time was (10.9±6.1) min, Cardiology Department response to informed consent confirmation time was (31.4±30.4) min, and the informed consent confirmation to out of emergency room time was (39.5±31.6) min; the transit time was (4.4±1.3) min; the intervention time was (35.2±13.1) min. DTB and emergency retention time of the standard DTB group were significantly shorter than those of the non-standard DTB group (P < 0.05). There were significant differences in DTB, emergency retention time and the informed consent confirmation to out of emergency room time between the working time group and the non-working time group (P < 0.05). There were no significant differences in DTB and its time points between the self-paid group and the non-self-paid group (P>0.05). DTB and emergency retention time in the 2020 group were significantly shorter than those in the 2018 group (P < 0.05).
      Conclusion  Obtaining informed consent and interventional catheterization preparation are the main factors for DTB extension in emergency STEMI patients. Establishing a standard process of pre-hospital and in-hospital seamless connection can effectively shorten DTB.
