title: [Clinical outcomes of trimetazidine in patients with acute ST segment elevation myocardial infarction without ST segment resolution after primary percutaneous coronary intervention].
abstract: OBJECTIVE
  To evaluate prospectively the clinical outcomes of trimetazidine (TMZ) in patients with acute ST segment elevation myocardial infarction (STEMI) without ST segment resolution (STR) after primary percutaneous coronary intervention (PPCI).
  
  
  METHODS
  From August 2005 to October 2007, 138 acute STEMI patients without STR after PPCI were randomly assigned to either with TMZ therapy (TMZ group, n = 70) or without TMZ (control group, n = 68). Baseline characteristics, PCI features and clinical outcomes during hospitalization were compared between the two groups. Left ventricular ejection fraction (LVEF) and major adverse cardiac events (MACE, including death, re-infarction and target vessel revascularization) at Days 30 and 180 after discharge were also compared.
  
  
  RESULTS
  The baseline clinical characteristics were comparable between the two groups. There was no significant difference in MACE rates at Days 30 and 180 between the two groups (10/70 vs 11/68, P > 0.05; 15/70 vs 13/68, P > 0.05, respectively). The LVEFs of TMZ group at Days 30 and 180 were significantly superior to the control group (51 +/- 8)% vs (45 +/- 7)%, P < 0.05; (56 +/- 7)% vs (49 +/- 8)%, P < 0.05, respectively).
  
  
  CONCLUSIONS
  Use of TMZ for patients with acute STEMI without STR after primary PCI can improve the left ventricular function at Days 30 and 180.
