Acute and Long-term Clinical Outcomes after Coronary Stenting of CrossFlex, GFX and NIR Stents

Abstract

Background and Objectives:New coronary stents are displacing a for the broader array of lesions. However, some controversy but disagreement remains as to which device is more advantageous and whether the design determines outcomes. The present study investigated investigates the impact of the stent design on the early and one year outcomes. Materials and Method:A retrospective analysis of 350 patients with 378 lesions (60±10 years, 265 male), who that underwent 181 CrossFlex, 95 GFX, 102 NIR coronary stentings at Chonnam National University Hospital from January 1996 to December 1999, was performed. The early procedural success rates, major adverse cardiac events (MACE) within one year and the follow-up angiographic findings in 227 patients (240 lesions, follow-up duration=8.1±5.9 months) among the three groups were compared among three groups. Results:There were no significant differences in the baseline clinical and angiographic characteristics except in the lesion length (CrossFlex:GFX:NIR=11.5±5.2:14.5±6.7:13.9±5.7 mm, p<0.05). There were no significant differences in the early angiographic success rates among the three groups (CrossFlex:98.9%, GFX:100.0%, NIR:99.0%). There were no significant differences in the late luminal loss (CrossFlex:GFX:NIR=1.03±0.69:1.11±0.75:1.09±0.70 mm, p=NS), the 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 the three groups. Conclusion:Despite the different lesions lengths, the early and late angiographic outcomes, and MACE within one year were not different among three different types of coronary stents.
