NATICK, Mass., Sept. 25 /PRNewswire/ -- Boston Scientific Corporation (NYSE: BSX) today announced three-year follow-up data from the HORIZONS-AMI trial. The trial, sponsored by the Cardiovascular Research Foundation (CRF) with grant support from Boston Scientific and The Medicines Company (Nasdaq: MDCO), is designed to determine the safety and efficacy of the TAXUS® Express2™ Paclitaxel-Eluting Coronary Stent System compared to bare-metal stenting in patients experiencing an acute myocardial infarction (AMI), or heart attack. With 3,006 patients enrolled worldwide, HORIZONS-AMI is the largest randomized trial to compare the use of drug-eluting stents to bare-metal stents for AMI patients. Analysis of the data was presented by Gregg W. Stone, M.D., Professor of Medicine and the Director of Research and Education at the Center for Interventional Vascular Therapy at the Columbia University Medical Center/New York-Presbyterian Hospital and Principal Investigator of the trial, at CRF's annual Transcatheter Cardiovascular Therapeutics scientific symposium in Washington, D.C.
"Follow-up data from the HORIZONS-AMI trial continue to show that, in patients with AMI, paclitaxel-eluting stents were superior in efficacy to bare-metal stents and had a comparable safety profile," said Dr. Stone. "Significant reductions in measures of re-intervention at three years were observed with no evidence of late catch-up."
HORIZONS-AMI demonstrated that the TAXUS Express Stent significantly reduced clinical and angiographic restenosis compared to an otherwise identical bare-metal Express® control stent. After three years follow-up, the primary efficacy endpoint of ischemia-driven target lesion revascularization (TLR) was 9.4 percent for patients treated with TAX
