ABSTRACT
<p><b>OBJECTIVE</b>This study was performed to evaluate the relationship between the stent fracture and restenosis after drug-eluting stent implantation.</p><p><b>METHODS</b>The study enrolled 536 patients with angiographies during stenting procedure and follow-up, the patients were divided into DES group (n=397) and BMS group (n=139). The coronary angiography images were analyzed to detect restenosis and stent fracture.</p><p><b>RESULTS</b>Restenosis rate was significantly lower in DES group (31/397, 7.8%) compared that in BMS group (30/139, 21.6%, P<0.05). Stent fracture (n=5) was found only in DES group and not in BMS group (P<0.05). Restenosis were found in all stent fracture segments. The stent fracture developed at the angulated tortuosity lesions.</p><p><b>CONCLUSION</b>Stent fracture is one of the causes of restenosis after drug-eluting stents implantation and related to implantation of long DES stent at the location of angulated tortuosity lesions.</p>
