title: [Early ST resolution after successful primary PCI is related to a favorable outcome in ST elevated AMI patients].
abstract: OBJECTIVE
  To analyze the relationship between the early ST resolution magnitude and TIMI flow, MACE and the cardiac function in ST elevated AMI (STEMI) patients after successful primary PCI.
  
  
  METHODS
  A total of 120 consecutive patients with STEMI underwent primary PCI within 12 hours after the onset of chest pain were enrolled in this study, the ST segment resolution was calculated and the patients were divided into group A (n = 81, Sigma STE resolved > or = 50%) and group B (n = 39, Sigma STE resolved < 50%). TIMI flow after PCI, clinical events up to 30 days post PCI and cardiac function 30 days post PCI were assessed.
  
  
  RESULTS
  LVEF was higher in group A than that of group B (58.6% +/- 7.1% vs. 50.5% +/- 7.1%, P < 0.05). There are fewer patients with Killip III and IV in group A than in group B (1.2% vs. 12.8%, P < 0.05). The incidence of in-hospital MACE was also significantly less in group A than in group B (0 vs. 7.7%, P < 0.001). As expected, there were more patients with TIMI 3 flow (95.1% vs. 79.5%, P < 0.05) and fewer TIMI 2 (4.9% vs. 20.5%, P < 0.05) flow post PCI in group A than in group B and all 3 patients with MACE were group B patients with TIMI 2 flow.
  
  
  CONCLUSIONS
  Early ST resolution post PCI represents improved myocardial perfusion and function and is related to a favorable clinical outcome in STEMI patients.
