title: Reperfusion times of ST-Segment elevation myocardial infarction in hospitals.
abstract: OBJECTIVE
  To investigate the reperfusion time in patients with ST-segment elevation myocardial infarction (STEMI) in Henan Province, China, and discuss the strategies for shortening that period.
  
  
  METHODS
  The reperfusion times of 1556 STEMI cases in 30 hospitals in Henan Province were analyzed from January 2008 to August 2012, including 736 cases from provincial hospitals, 462 cases from municipal hospitals and 358 cases from country hospitals. The following data: Time period 1 (from symptom onset to first medical contact), Time period 2 (from first medical contact to diagnosis), Time period 3 (from the diagnosis to providing consent), Time period 4 (from the time of providing consent to the beginning of treatment) and Time period 5 (from the beginning of treatment to the patency) were recorded and analyzed.
  
  
  RESULTS
  In patients receiving primary percutaneous coronary intervention, the door-to-balloon time of provincial hospitals and municipal hospitals was 172±13 minutes and 251±14 minutes, respectively. The hospitals at both levels had a delay comparison of 90 minutes largely caused by the delay in the time for obtaining consent. In patients receiving thrombolysis treatment, the door-to-needle times of provincial hospitals, municipal hospitals and country hospitals were 86±7, 91±7 and 123±11 minutes, respectively. The hospitals at all levels had delays lasting more than 30 minutes, which was mainly attributed to the delay in the time for providing consent. Compared with the time required by the guidelines, the reperfusion time of patients with STEMI in China is evidently delayed. In terms of China's national conditions, the door-to-balloon time is too general. Therefore, we suggest refining this time as the first medical contact-diagnosis time, consent provision time, therapy preparation time and the start of therapy balloon time.
  
  
  CONCLUSIONS
  Compared to the time required by the guidelines, the reperfusion time of patients with STEMI in China was obviously greater. In terms of China's national conditions, the door to balloon time is not applicable. So it is suggested to refine it as the first medical contact-diagnosis time, providing consent time, therapy prepare time and the start of therapy - balloon time.
