OBJECTIVES: We sought to evaluate late clinical outcomes following elective percutaneous coronary interventions for saphenous vein graft with planned abciximab use in diabetics. BACKGROUND: Diabetes adversely affects long-term outcomes after percutaneous coronary intervention including percutaneous coronary intervention of saphenous vein grafts. Glycoprotein IIb/IIIa inhibitors reduce adverse outcomes of native vessel percutaneous coronary intervention in diabetics; however, their effects in diabetic patients undergoing percutaneous coronary interventions of saphenous vein grafts is not known. METHODS: We evaluated 509 elective percutaneous coronary interventions of saphenous vein grafts. Glycoprotein IIb/IIIa inhibitors were used in 99% of the percutaneous coronary interventions. Distal protection devices were not used. Clinical follow-up (mean 30+/-20 months) was available in 369/397 (93%). RESULTS: Overall, procedural success rate was 97% and was similar for diabetics and non-diabetics. Procedural major adverse cardiac events occurred in 4.8% diabetics, and 4.1% non-diabetics (p = NS). Late outcomes were similar for diabetics and non-diabetics with major adverse cardiac event rates of 57.6%, and 54.9%, respectively, p=NS. Multivariate logistic regression identified graft age and the presence of thrombus as predictors of increased late major adverse cardiac events. CONCLUSIONS: Following routine use of abciximab, late outcomes after percutaneous coronary interventions of saphenous vein grafts were similar for diabetics and non-diabetics suggesting that the historically observed adverse effect of diabetes on late outcomes after percutaneous coronary interventions of saphenous vein grafts may be attenuated by glycoprotein IIb/IIIa use. Selective use of glycoprotein IIb/IIIa inhibitor should be considered for diabetics undergoing percutaneous coronary interventions of saphenous vein grafts.
