First-generation drug-eluting stents (DES) with controlled release of sirolimus or paclitaxel from durable polymers compared with bare-metal stents have been consistently shown to reduce the risk of repeat revascularization procedures due to restenosis. The superior efficacy was found across a wide range of patients and lesion subsets and persisted up to 5 years whereas similar outcomes have been observed in terms of death and myocardial infarction. Newer generation DES have been developed with the goal to further improve upon the safety profile of first-generation DES while maintaining efficacy. These platforms include DES with improved and more biocompatible durable polymers, DES using bioabsorbable polymers for drug release, DES with polymer-free drug release, and fully bioabsorbable DES. Newer generation DES with durable polymers such as zotarolimus-eluting or everolimus-eluting XIENCE V stents have been directly compared with first-generation DES. Most recent results of large scale clinical trials are encouraging in terms of similar or increased efficacy while improving safety by reducing the rates of myocardial infarctions and stent thrombosis. DES using biodegradable polymers for drug release represent the next technological modification and preliminary results are favorable and demonstrate similar angiographic and clinical efficacy as first-generation DES, but only longer term follow-up and investigation in larger patient cohorts will determine whether their use is associated with improved long-term safety. Fully bioabsorbable stents represent another innovative approach. Whether this innovative concept will enter into clinical routine remains yet to be determined.
