헤파린 부착 JO스텐트와 미부착 JO스텐트 삽입술 후의 장기 추적 성적 비교

Abstract

The risk of acute or subacute closure after angioplasty has been minimized by using stent deployment. However, restenosis rating 20% ∼30% after stenting is still most important limiting factor for stenting. We investigated a long-term effect of implantation of a heparin-coated JO stent compared with the use of un-coated JO steno. Thirty eight patients were assigned heparin-coated JO stent{21 patients, JO(H)} or uncoated JO stent(17 patients, JO). All clinical and angiographic parameters were retrogradely reviewed. They were followed up monthly and performed follow-up coronary angiography 7 months later. The clinical and angiographic parameters were statistically not different between two groups, except hypertension {JO:18%, JO(H):52%, p＜0.05}. The reference diameter was 3.12±0.53mm in 10 and 2.85 ±0.43mm in JO(H) (p=0.071). The minimum luminal diameter after stenting was not significantly different{2.91±0.52mm in JO, 2.78±0.42mm in JO(H), p=0.381}. The restenosis rate of JO was 32% and JO(H), 35%(p=0.545). Over seven months follow up, it seems that a strategy of elective stenting with heparin-coated JO stent was not more effective than uncoated JO stent.
