Direct Implantation of Drug Eluting Stents does not reduce restenosis

Original:&nbsp;Direct drug-eluting Stenting to reduce stent reestenosis (STRESSED).&nbsp;Reference:&nbsp;Wouter S. Remkes et al. J Am Coll Cardiol Intv, 2014;7: 751-8. Direct stenting, without predilation, has been considered a safe and effective technique that reduces procedural time, radiation exposure, contrast material and costs; however, the pertinent studies tested conventional stents only.&nbsp; This study aimed at assessing whether<a href="https://solaci.org/en/2014/08/26/direct-implantation-of-drug-eluting-stents-does-not-reduce-restenosis/" title="Read more" >...</a>
