The treatment of elderly patients with coronary artery disease (CAD) is challenging because this population is complex and greatly expanding. Drug-eluting stents (DES) generally improve the outcome in high-risk cases. We evaluated the clinical impact of different first-generation DES, i.e., sirolimus-eluting stents (SES) and paclitaxel-eluting stents (PES), in this context. A prospective, nonrandomized, single-center, allcomers registry consecutively enrolling all patients aged ≥75 years eligible for percutaneous coronary intervention (PCI) with DES was carried out. Only one type of DES was implanted per protocol for each patient. Two groups were identified according to the type of implanted stent, i.e., SES and PES. The primary end point encompassed major adverse cardiac events (MACE), including death, myocardial infarction, and target lesion revascularization (TLR). The secondary end point encompassed the rate of definite/probable stent thrombosis and target vessel revascularization (TVR). From June 2004 to May 2008, 151 patients were enrolled. Among them, 112 (74.2%) received SES and 39 (25.8%) received PES. Baseline clinical characteristics were similar, while few angiographic features (ostial location, stent diameter, proximal reference vessel diameter) showed minor differences. At the median follow-up of 22.6 months, primary and secondary end points did not significantly differ in terms of MACE (SES 12.5% vs PES 20.5%, P = 0.3), death (SES 5.4% vs PES 7.7%, P = 0.7), myocardial infarction (SES 4.5% vs PES 10.3%, P = 0.2), TLR (SES 2.7% vs PES 2.6%, P = 1.0), stent thrombosis (SES 1.8% vs PES 5.1%, P = 0.3), and TVR (SES 1.8% vs PES 0%, P = 0.6). In this real-world population of elderly patients treated by DES-PCI for CAD, the overall efficacy and safety have been excellent in both DES, and the choice between SES and PES did not influence the clinical outcome.

Abstract
The treatment of elderly patients with coronary artery disease (CAD) is challenging because this population is complex and greatly expanding. Drug-eluting stents (DES) generally improve the outcome in high-risk cases. We evaluated the clinical impact of different first-generation DES, i.e., sirolimus-eluting stents (SES) and paclitaxel-eluting stents (PES), in this context. A prospective, nonrandomized, single-center, allcomers registry consecutively enrolling all patients aged ≥75 years eligible for percutaneous coronary intervention (PCI) with DES was carried out. Only one type of DES was implanted per protocol for each patient. Two groups were identified according to the type of implanted stent, i.e., SES and PES. The primary end point encompassed major adverse cardiac events (MACE), including death, myocardial infarction, and target lesion revascularization (TLR). The secondary end point encompassed the rate of definite/probable stent thrombosis and target vessel revascularization (TVR). From June 2004 to May 2008, 151 patients were enrolled. Among them, 112 (74.2%) received SES and 39 (25.8%) received PES. Baseline clinical characteristics were similar, while few angiographic features (ostial location, stent diameter, proximal reference vessel diameter) showed minor differences. At the median follow-up of 22.6 months, primary and secondary end points did not significantly differ in terms of MACE (SES 12.5% vs PES 20.5%, P = 0.3), death (SES 5.4% vs PES 7.7%, P = 0.7), myocardial infarction (SES 4.5% vs PES 10.3%, P = 0.2), TLR (SES 2.7% vs PES 2.6%, P = 1.0), stent thrombosis (SES 1.8% vs PES 5.1%, P = 0.3), and TVR (SES 1.8% vs PES 0%, P = 0.6). In this real-world population of elderly patients treated by DES-PCI for CAD, the overall efficacy and safety have been excellent in both DES, and the choice between SES and PES did not influence the clinical outcome.
