title: [Cause of in-hospital death among acute myocardial infarction patients undergoing primary percutaneous coronary intervention in Beijing].
abstract: OBJECTIVE
  To analyze the cause of in-hospital death among acute myocardial infarction patients undergoing primary percutaneous coronary intervention (PPCI) in Beijing area to evoke better individualized preventive approach.
  
  
  METHODS
  In-hospital mortality and causes were analyzed based on database from Beijing percutaneous coronary intervention registry study (BJPCI Registry) in 2010.
  
  
  RESULTS
  A total of 4660 PPCI patients from 48 hospitals were included. In-hospital mortality was 2.4% (n = 110). Cardiogenic shock (39.1%, 43/110), mechanical complications (28.2%, 31/110) and intervention-related complications [28.2%, 31/110: procedure related (n = 28), drug related (n = 3)] were the leading causes of in-hospital death. Five deaths was attributed to comorbidity related reason (4.5%, 5/110). The in-hospital mortality had no significant difference among hospitals of different grade or total annual PCI (all P > 0.05). In-hospital mortality was slightly higher in hospital with annual PPCI < 300 than in hospitals with annual PPCI ≥ 300 (2.9% vs. 1.8%, P < 0.05).
  
  
  CONCLUSIONS
  Cardiogenic shock, mechanical complications and intervention-related complications are the main causes of in-hospital death among acute myocardial infarction patients receiving PPCI.
