Safety Of Drug-Eluting Stents: First Results From The ISAR-TEST-4 Study

Drug-eluting stents (DES), which slowly release medication to inhibit the build-up of scar tissue, have proved very successful in preventing restenosis (renarrowing) of stented coronary arteries. However, several studies have shown persistent risk of blood clot formation inside DES over a longer time period after implantation than observed with bare metal stents.
