试验设计背景:
- 已往研究大多入组简单病变 , 非临床实际情况
- 目前 1 代支架的不足 : 涂层即使生物相容性好,仍有过敏、炎症、内皮化不全至血栓形成
第二代 DES 背景Resolute DES Xience V DES

purpose of this study
Resolute All Comers trial,--- was to compare the Resolute zotarolimus-
eluting stent with an everolimus eluting stent in an unrestricted, multicenter, open-label, randomized, controlled, noninferiority trial in patients undergoing percutaneous coronary intervention (PCI) in everyday clinical practice.

RESOLUTE All Comers 试验 1 年结论
• RESOLUTE-AC 试验设计充分反映了日常真实的临床情况,其结果具有重要的临床意义
• Resolute 达到主要终点 TLF 、各个临床终点均表现优异 , 并不比 Xience V 支架弱
• 与既往第 1 代 DES 临床试验结果相比,新一代支架为临床提供了一个非常好的选择
In conclusion, the new-generation zotarolimus-eluting stent was found to be as safe and effective as the everolimus-eluting stent in a group of patients for whom the procedure was considered to be predominantly off-label.
讨论
1. 与第一代支架比的优势
2. All comers 设计的意义
3. TVF 作为一级终点的意义
4. 支架内血栓事件的差别与临床终点事件如总死亡、心脏性死亡差别在研究中的细微不一致
