s670与s7冠状动脉内支架的对比研究

A comparison of s670 and s7 intracoronary stents

目的 比较s7和s6 70冠状动脉内支架的临床应用。方法 回顾性分析 6 8例接受s7和s6 70冠脉内支架植入术患者的临床随访结果。结果 32例植入 32枚s7支架 ,其中A型病变 4处 ,B型病变 19处 ,C型病变 9处 ,成功率 10 0 %;36例植入 36枚s6 70支架 ,其中A型病变 2处 ,B型病变 2 4处 ,C型病变 10处 ,置入 35枚 ,成功率 97.2 %。 1例因支架远端撕裂而植入coroflex支架。两组均随访半年。s7组 2例心绞痛复发 (6 .2 5 %) ,但无死亡、再梗塞及再次血运重建 ;s6 70组 3例心绞痛复发 ,1例再次血运重建 ,1例死亡 (13.8%)。结论 s7和s6 70冠状动脉内支架均可安全有效地应用于冠心病的介入治疗。

Objective To compare the clinical utility of s7 and s670 intracoronary sents in the management of patients with coronary artery disease. Methods The clinical follow-up outcomes of 68 patients after implantation of s7 (n=32; group Ⅰ) and s670 (n=36;group Ⅱ) intracoronary stents were retrospectively analysed. Results The successful procedure rates were 100% in group Ⅰ and 97.2% in groupⅡ. The follow-up period was six months for both groups. In group Ⅰ, there were no death, no re-infarction and no revascularization but 2 patients experienced reccurrence of angina ( 6.25%). In group Ⅱ, there were 1 death, 1 patient undergoing revascularization, 3 patients suffering from reccurrence of angina ( 13.8%). Conclusions Both s7 and s670 intracoronary stents appear to be safe and effective in the treatment of coronary lesions with favorable outcomes.
