The appearance a few years ago of drug-eluting stents as a tool for the treatment of coronary vessel stenosis was hailed by most of the cardiology community as a major advance over bare-metal stents. Now, findings from 2 studies presented in September at the World Congress of Cardiology in Barcelona, Spain, have dampened that enthusiasm.
The studies' findings give ammunition to those who suggest percutaneous coronary intervention (PCI) using drug-eluting stents was being oversold in light of a lack of evidence surrounding long-term safety and efficacy—especially in patients with stable chronic angina, a relatively benign condition.
