title: Abciximab offers greater benefits to insulin-dependent diabetic patients undergoing coronary stent implantation.
abstract: OBJECTIVE
  Abciximab use does not exceed 25% in most of the studies on diabetic patients undergoing stent implantation. The aim of this study was to evaluate whether abciximab could be more beneficial in different subgroups such as insulin-dependent (ID) patients and whether its use could provide additional benefits to those afforded by drug-eluting stents in these patients.
  
  
  METHODS
  A total of 373 consecutive diabetics [223 non-insulin-dependent (NID) and 150 ID patients] who had undergone stent implantation were examined with a follow-up of 25.6+/-16.2 months. Abciximab was used in 21.7%.
  
  
  RESULTS
  The abciximab-treated group had a lower rate of revascularization (26.8% vs. 15.8%. P=.02). The results by subgroups were as follows: NID nonabciximab, 23.5%; NID abciximab, 19% (P=NS); ID nonabciximab, 32.7%; ID abciximab, 12.2% (P=.05). In multivariate analysis, the restenosis predictors were insulin dependency (OR, 2.7), abciximab use (OR, 0.18), stent diameter (OR, 0.18).
  
  
  CONCLUSIONS
  Abciximab use in diabetics with stent implantation has a favorable effect by reducing the need for new revascularization. This benefit is more evident in ID patients; the negative prognosis effect of being insulin-dependent is eliminated, and the percentage of events in this population over a long follow-up period is equal to those in NID patients.
