Are Drug-Eluting Stents the Preferred Treatment for Multivessel Coronary Artery Disease?

Drug-eluting stents (DES) constitute a major breakthrough in restenosis prevention after initial percutaneous coronary intervention (PCI). Target lesion and vessel revascularization rates of <10% at six months follow-up represent a significant medical advance. Many cardiologists consider it reasonable to assume that PCI using DES ought to be considered equivalent, if not superior, to bypass surgery. The argument made is that in previous randomized clinical trials comparing PCI to coronary artery bypass grafting, restenosis was the determining factor favoring surgery, an event that clinical experience suggests is no longer as frequent. In the absence of a definitive clinical trial to support this view, how should the prudent, cutting edge cardiologist evaluate the data and manage their patients? [Copyright &y& Elsevier]
