EurekAlert! -- A systematic review of medical evidence has determined drug-eluting stents (DES) outperform bare metal stents (BMS) for revascularization of chronic total occlusions. Researchers found coated stents reduce restenosis and target revascularization, offering a safe approach with similar adverse events as BMS. Full findings are available in the February issue of Catheterization and Cardiovascular Interventions, a journal published by Wiley-Blackwell on behalf of The Society for Cardiovascular Angiography and Interventions.
