title: [The Chinese registry on reperfusion strategies and outcomes in ST-elevation myocardial infarction].
abstract: OBJECTIVE
  To analyze the current use of reperfusion strategies and the outcomes of patients with ST elevation acute coronary syndromes (ACS) in China.
  
  
  METHODS
  A total of 518 consecutive patients (371 male and 147 females, mean age 65 +/- 11) with ST elevation ACS or newly discovered left bundle branch block were registered from 20 hospitals from 5 regions (ranging from large regional centre hospitals to small county hospitals) in China. Patient general characteristics, reperfusion patterns and outcomes were analyzed. Patients were followed up for 3 months.
  
  
  RESULTS
  The median time from pain onset to presentation at the hospital was 4 hours. Pre-hospital delay > 12 hours was found in 20% patients. Fifty-six percent patients (292/518) underwent reperfusion therapy (134 with primary percutaneous coronary intervention and 158 with fibrinolysis). The median time from admission to reperfusion (door-to-needle) was 65 min in fibrinolysis group and 110 min (door-to-cath) in primary PCI group respectively. Urokinase was used in 67% (106/158) patients underwent fibrinolysis. Multivariate logistic regression analysis showed that age >/= 75 years (P < 0.01), previous myocardial infarction (P < 0.01) and history of congestive heart failure (P < 0.05) were associated with no reperfusion therapy. Mortality and congestive heart failure rates were significantly higher in patients with no reperfusion therapy not only at discharge (P < 0.01) but also at 3 months (P < 0.01) compared to patients underwent reperfusion. The incidence of combined outcomes (death or MI, and death, MI or Strobe) was also higher in patients without reperfusion therapy at 3 months (all P < 0.01) compared to patients underwent reperfusion. There were no differences on combined outcomes between fibrinolysis and primary PCI subgroups.
  
  
  CONCLUSIONS
  Reperfusion therapy was the primary treatment of choice to improve the outcomes of patients with ST elevation ACS. Strategies to increase reperfusion therapy rate for ST elevation ACS are urgently needed in China.
