To the Editor: I have a number of concerns about the study by Dr Malenka and colleagues1 on outcomes following stenting in the bare-metal stent era vs drug-eluting stent era, which concluded that there was a decline in the need for repeat revascularization procedures. First, the authors excluded patients with any percutaneous coronary intervention (PCI) or coronary artery bypass within 1 year. These patients were likely to have bare-metal stents since the drug-eluting stent cohort was from the years immediately after these stents were introduced. Thus, some cases with restenosis within a year were likely to have been left out.
