Randomized comparison between polymer-free versus polymer-based paclitaxel-eluting stent: two-year final clinical results.

Circ Cardiovasc Interv. 2014 Jun;7(3):312-21, PMID: 24803435

Most drug-eluting stents currently in use are coated with a polymer carrying the drug that is released for several weeks. However, a durable polymer may provoke hypersensitive reaction, delayed artery healing, and eventually stent thrombosis. The aim of this study was to investigate the safety and efficacy of a polymer-free paclitaxel-eluting stent (PF-PES) versus a polymer-based PES (PB-PES).
