Authors identify important differences between drug-eluting stent brands
NATICK, Mass., May 11 /PRNewswire-FirstCall/ -- Boston Scientific Corporation (NYSE: BSX) today welcomed the publication of an article in the current edition of the Journal of American College of Cardiology (JACC) reviewing data on more than 19,000 patients from the Swedish national registry who were evaluated for restenosis, or the re-narrowing of arteries after percutaneous coronary intervention (PCI). The article reported that patients who received a TAXUS(R) Liberte(R) Paclitaxel-Eluting Stent had numerically lower incidences of repeat procedures to treat restenosis at two years as compared to patients treated with 'olimus-based drug-eluting stents (DES), including Cordis' Cypher(R) Stent and Medtronic's Endeavor(R) Stent. In the patients with diabetes, the TAXUS Liberte Stent demonstrated a statistically significant lower restenosis rate compared to the Endeavor Stent, which had more than two times the risk of repeat procedures.
The Swedish Coronary Angiography and Angioplasty Registry holds data on all patients undergoing PCI in Sweden. The objective of this independent study was to evaluate restenosis rates of drug-eluting stents in patients with and without diabetes in a real-world setting. The JACC article reported that both the TAXUS Liberte Stent and Boston Scientific's first-generation DES -- the TAXUS(R) Express(R) Stent -- were the only stents in the study showing no increased risk of restenosis for patients with diabetes as compared to those without diabetes. Both the Cypher Stent and Endeavor Stent showed significant increased risk of restenosis in patients with diabetes. In addition, the study showed that the TAXUS Liberte Stent had an approximately 23 percent lower restenosis rate at two years compared to the prior-
