Clinical predictors of stent thrombosis in the "real world" drug-eluting stent era.

Background: Drug-eluting stents (DESs) are effective in reducing restenosis and the need for repeat revascularization procedures in patients who undergo percutaneous coronary intervention (PCI). There is however an increased concern with the safety of DES with regard to stent thrombosis (ST). We examined the incidence of ST among patients who received DES and determined the clinical predictors.
