title: [Clinical efficacy and safety of emergent percutaneous coronary intervention for vein-grafts in the patients with acute myocardial infarction: comparison between age groups].
abstract: OBJECTIVE
  To evaluate the efficacy and the safety of emergent primary percutaneous coronary intervention (PCI) in the saphenous vein bypass graft (SVBG) of acute myocardial infarction (AMI), and compare the results between aged -patients with non-aged patients.
  
  
  METHODS
  Three hundred and nine consecutive AMI patients with culprit SVBG vessels, were analysed, including aged patients 213 cases(>or=70 years old), non-aged patients 96 cases(<70 years old), underwent the emergent primary PCI after confirmed below TIMI III perfusion(TIMI 0-TIMI II) in coronary angiographies. The immediate results and in-hospital outcomes were compared between two groups.
  
  
  RESULTS
  Procedural successful rate, re-occlusion rate, and emergency re-CABG had no significant differences between two groups. The rate of slow-flow/no-reflow and in-hospital mortality rate were significantly higher in elderly group (19.7% vs 10.4%, 9.4% vs 4.2%, both P<0.05), with no difference in the rate of the using of distal protection devices between two groups. The comparison of the rate of direct stenting in slow-flow/no-reflow subgroup with normal-flow subgroup, had not showed statistic difference (73.5% vs 67.3%, P>0.05). There was no statistic difference of heavy hemorrhage between two different age groups.
  
  
  CONCLUSIONS
  The primary PCI for the elderly AMI patients with infarction-related SVBG vessels, has higher risks in slow-flow/no-reflow and the mortality, even with using the distal protection devises and direct stents implantation.
