Abstract

BACKGROUND AND OBJECTIVES
New coronary stents are displacing for the broader array of lesions, but disagreement remains which device is more advantageous and whether design determines outcomes. The present study investigates the impact of stent design on early and one year outcomes.
MATERIALS AND METHODS
A retrospective analysis of 350 patients with 378 lesions (60+/-10 years, 265 male), that underwent 181 CrossFlex, 95 GFX, 102 NIR coronary stentings at Chonnam National University Hospital from January 1996 to December 1999, was performed. Early procedural success rates, major adverse cardiac event (MACE) within one year and follow-up angiographic findings in 227 patients (240 lesions, follow-up duration=8.1+/-5.9 months) were compared among three groups.
METHODS
1) There were no significant differences in the baseline clinical and angiographic characteristics except the lesion length (CrossFlex: GFX: NIR=11.5+/-5.2: 14.5+/-6.7: 13.9+/-5.7 mm, p<0.05). 2) There were no significant differences in early angiographic success rates among three groups (CrossFlex: 98.9%, GFX: 100.0%, NIR: 99.0%). 3) There were no significant differences in late luminal loss (CrossFlex: GFX: NIR=1.03+/-0.69: 1.11+/-0.75: 1.09+/-0.70 mm, p=NS), restenosis rates (CrossFlex: 30.6%, GFX: 30.8%, NIR: 28.4%, p=NS) and MACE (CrossFlex: GFX: NIR=27.6%: 29.5%: 27.5%, p=NS) among three groups.
CONCLUSION
Despite different lesions length, the early and late angiographic outcomes, and MACE within one year were not different among three different types of coronary stents.
