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 limit?ing 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 stent. Thirty eight patients were assigned heparin-coated JO stent {21 patients; JO(H)} or uncoated JO stent (17 patients; JO). All clinical and angiographic para?meters were retrogradely reviewed. They were followed up monthly and performed follow-up coronary angiography 7 months later. The clinical and angiographic parameters were statisti?cally not different between two groups; except hypertension {JO: 18%; JO(H):52%; p<0.05}. The reference diameter was 3.12±0.53mm in JO 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.
