title: [The clinical characteristics and prognosis of acute myocardial infarction complicated by cardiogenic shock].
abstract: OBJECTIVE
  To observe the effect of reperfusion therapy on the prognosis of acute myocardial infarction (AMI) complicated by cardiogenic shock (CS) in reperfusion era.
  
  
  METHODS
  89 cases of AMI with CS were included with 57 male and 32 female. 50 cases received conservative therapy and 39 cases reperfusion therapy. 28 of the 39 cases had successful reperfusion and 11 cases failed. 18 patients had intra-aortic balloon pump (IABP) within 1 hour of CS, they constituted an early group; 35 patients treated with IABP 1 hour after CS were of a late group. A group of 36 cases were not treated with IABP (no IABP group).
  
  
  RESULTS
  The mortality of the early group with IABP was significantly lower than that of the late and no IABP group (33.3% vs. 74.2% vs. 86.1%, P < 0.01). The mortality of the group with successful reperfusion was significantly lower than that of unsuccessful reperfusion and conservative no IABP group (42.8% vs. 81.8% vs. 84.0% , P < 0.01). logistic regression analysis showed that successful reperfusion therapy (OR 4.232, 95% CI 1. 07 - 12.730, P = 0.01) and THE TIME of using IABP (OR 0.22, 95% CI 0.063 - 0.764, P =0.017) were independent risk factors for death.
  
  
  CONCLUSIONS
  Early successful reperfusion and early institution of IABP were the most important therapeutic measures for reducing mortality of AMI complicated by CS.
