The Effect of Presence of Emergency Medicine Specialists on DTN Mean Time Patients with ST-Segment Elevation

Acute Myocardial Infarction (AMI) is one of the most common diseases throughout the world and is the leading cause of death in Iran. Reperfusion therapy is the cornerstone of therapy among these patients. Early thrombolytic treatment leads to better restoration of coronary blood flow and a significant decrease in mortality and re-infarction. This article aimed to study the effect of the presence of emergency medicine specialists on time improvement of treatment of patients diagnosed with ST-Elevation Myocardial Infarction (STEMI) visiting the emergency ward of Khatam-Al-Anbia Hospital, Zahedan, Iran.

This is a descriptive study with retrospective approach. A total of 1008 STEMI medical files were reviewed before and after the presence of emergency medicine specialist. The study aimed to investigate the DTN mean time of STEMI patients visiting Khatam-Al-Anbia Hospital of Zahedan in 2015 before and after the presence of emergency medicine specialist.

A total of 1008 files were reviewed: Group I: 504 files from March 21^st, 2013 to September 22^nd, 2013 [First half of 1392 Iranian Year] and Group II: 504 files from September 23^rd, 2014 to March 20^th, 2015 [Second half of 1393 Iranian Year]. The mean age was 56.17±13.81. According to Chi-square test, 373 were female and 363 were male. DNT mean time in Group II was significantly less than the time in Group I, 49.83±17.82 opposed to 23.19±15.60.

According to the findings, the presence of emergency medicine specialist caused a decline in DNT time of STEMI patients. Accordingly, the mortality rate and complication of STEMI patients declined.
