The Cardiovascular Research Foundation (CRF) will present results of the largest meta-analysis to date comparing mortality rates for drug-eluting stents (DES) versus bare metal stents (BMS) at the Drug-Eluting Stent Revolution VII meeting tomorrow evening in Chicago.
The analysis—which includes approximately 180,000 patients from 52 studies—was performed by a team of researchers led by Ajay J. Kirtane, MD, Assistant Professor of Clinical Medicine and an interventional cardiologist at NewYork-Presbyterian Hospital/Columbia University Medical Center, and Gregg W. Stone, MD, Chairman of CRF and Professor of Medicine at Columbia University Medical Center and Director of Cardiovascular Research and Education at the Center for Interventional Vascular Therapy at NewYork-Presbyterian Hospital.
Drs. Kirtane and Stone conducted two parallel meta-analyses examining DES vs. BMS use in both randomized, controlled trials and in observational registry analyses. The overall analysis represents the largest systematic overview of “real-world” (comprising both on-label and off-label) DES use to date and incorporates an updated overview of both the published literature as well as the most recent data from several unpublished studies presented in the last year.
“The findings from these parallel studies are striking,” said Dr. Stone.
The meta-analysis of 22 randomized trials included more than 9000 patients with recent follow-up from previously published trials. According to the results, “DES resulted in small non-significant reductions in death and MI, with a greater than 50% decrease in subsequent TVR procedures,” said Dr. Stone, adding that these findings are consistent with both on-label and off-label use of DES.
