With the use of bare-metal stents, the cardiologist often saw an instent restenosis, which led to the invention of drug-eluting-stents. Unfortunately, the incidence of stent thrombosis rose with the use of drug-eluting stents. Knowing that many of the drug-eluting stents were used in lesions that were considered off-label, e.g. complex lesions, the rise of incidence of stent thrombosis has to be interpreted with care. There is no knowledge yet to wether the use of bare-metal stents in off-label lesions also raises the rate of stent thrombosis. The aim of this study is to determine the rate of stent thrombosis in drug-eluting vs. bare metal stents in off- vs. on-label use. Also, the predictors for stent thrombosis were sought after. Between 07/2002 and 10/2006, PCI was performed on 5945 patients using BMS (68%) or DES (32%). The follow-up period for definitive stent thrombosis (ARC criteria) was one year. 76 patients (1,27%) suffered from a definitive stent thrombosis. An additional consecutive 786 patients without stent thrombosis were included in the analysis. Procedural, angiographic and clinical parameters were analysed to define predictors of stent thrombosis. On-label or off-label implantation of stents (FDA-approved indications) was included as parameter in the analysis. 51% of the patients (n=434) received a stent according to the FDA-guidelines, 49% (n=428) of the patients had a stent implanted for an off-label indication. Predictors of stent thrombosis were percutaneous coronary intervention (PCI) in acute myocardial infarction (OR=4,91, p<0.001), treatment of bifurcation lesions (OR=3,43, p<0,001), stent length per mm (OR=1,07, p<0,001), implantation of multiple stents (OR=4,31, p<0,001), and stent implantation outside of FDA indications (OR=6,13, p<0,001). The risk of stent thrombosis was increased for bare-metal as well as drug-eluting stents. In a multivariate analysis PCI in acute myocardial infarction (OR=3,68, p=0,004), treatment of bifurcation lesion (OR=3,63, p=0,003), stent length in mm (OR=1,04, p=0,012) and implantation of multiple stents (OR=2,47; p=0,003) remained predictors of stent thrombosis.
