Methods Ninety-one consecutive patients with 156 lesions who underwent coronary cypher (n = 68 lesions) and firebird (n = 88 lesions) implantation, quantitative coronary angiography (QCA) was performed at the time of stent implantation and subsequently at 8 months post-stenting. Small vessel disease was defined as ≤2.5 mm of reference vessel diameter measured by QCA. Major adverse cardiac events (MACE) including death, thrombosis, nonfatal myocardial infarction and target lesion revascularization (TLR) were compared between the two groups. Results Baseline clinical characteristics and angiographic parameters were similar between the two groups. Seven-month angiographic follow-up, the late loss was not different between the two groups (0.14 ± 0.38 mm vs 0.13 ± 0.17 mm, P > 0.05). Similarly, overall thrombosis rate were similar in both groups (1.5% vs 1.1%, P > 0.05). However, in-stent restenosis as well as in-segment restenosis rate were significantly higher in cypher group than that in firebird group (4.4% vs 0% and 19.1% vs 3.4%, P = 0.047 and P = 0.001 respectively). TLR was also higher in the cypher group (10.3% vs 2.3%, P = 0.033) compared with firebird group. Conclusions In this small sample size, non-randomized study, the data indicated that implantation of firebird stent for the treatment of small coronary lesion showed more favorable results in respective of restenosis compared with cypher stent implantation. A multi-center, large-sample size, randomized study, therefore, may be warranted.展开更多

Methods Quantitative angiography was performed on 60 cases (67 successfully dilated lesions) after angio-plasty over 6-months follow-up, and both univariate and multivariate logistic regression analysis were done to i-dentify the correlations of restenosis with clinical factors. Results The total restenosis rate was 31. 3% (21 of 67 lesions), and according to univariate analysis the patients who underwent coronary stenting≥ 3. 5mm had a lower rate of restenosis ( P < 0. 01). Collateral circulation to the obstruction site, high maximal inflation pressure, smoking and the less minimal lumen diameter after PTCA made the rate of restenosis higherower ( P < 0. 05) . Multivariate logistic regression analysis showed that coronary stenting ≥3. 5mm had a low rate of restenosis, but high maximal inflation pressure and smoking made the restenosis rate higher. Conclusion Coronary stent size, maximal inflation pressure and. smoking were independent predictors for restenosis.展开更多
