International Circulation: We’re here with Doctor Mehran; Doctor， what are your thoughts about the long-term safety of sirolimus eluting stents compared with bare-metal stents?
国际循环： 和普通金属支架相比，您觉得西罗莫司洗脱支架长期安全性如何？

Prof. Roxana Mehran: Well， so far based on the data that we have – and we now have at least five-year data from large randomized clinical trials – there donot  appear to be any safety issues whatsoever that concern me.  In fact， I feel that the sirolimus-eluting stent—the Cypher stent—is really the most durable one. We have the most information on that stent and on the paclitaxel-eluting Taxus stent. These are the first-generation of drug-eluting stents.  We have the luxury of having very long-term data on both the safety and efficacy of these stents. 

Prof. Roxana Mehran: 根据现有的资料，目前我们有关于大型随机临床试验至少5年的研究资料，似乎没有任何我们所担心的安全问题。事实上我认为西罗莫司洗脱支架，Cypher支架是真正最耐久的支架，我们有关于该支架大量的研究资料，或者紫杉醇洗脱；这些都是第一代药物洗脱支架。我们有大量关于长期安全性和疗效的资料。
