Vlachojannis, MD, PhD§; Lisette Okkels Jensen, MD‖; Evald H. Christiansen, MD, PhD¶; Klára Berencsi, MStat‖; Marco Valgimigli, MD#; Carlotta Orlandi, MD∗; Mario Petrou, MD†; Claudio Rapezzi, MD∗; Gregg W. Stone, MD∗∗

Background: Previous meta-analyses have investigated the relative safety and efficacy profiles of different types of drug-eluting stents (DES) and bare-metal stents (BMS); however, most prior trials in these meta-analyses reported follow-up to only 1 year, and as such, the relative long-term safety and efficacy of these devices are unknown. Many recent studies have now reported extended follow-up data.
