International Circulation:  At this great wall conference， the ESC-CSC heart rate investigation project called CLARIFY has been initiated.  Could you please give us a brief introduction of this project? What are the rationale， design and objective of this project?
《国际循环》：在这次长城会议上，启动了名为CLARIFY中欧心率调查项目的研究，能请您简要介绍下这个项目吗？

Roberto Ferrari:  This is a project relating outpatients with coronary artery disease and is a registry for the need and how these patients are taken care of.  It is a worldwide registry which is aiming to include at least 30，000 patients， and there would be follow-up for 5 years.  We realized that in Europe and throughout the world we do not have enough data on the real world care of these patients.  We do have data from clinical trials which often target hospitalized patient populations and there are， in the clinical trials， several biases because very often the way a patient is to be treated is pre-specified and we would like to know the truth of treatment.  This is also a new strategy of the European Society to provide the real world data.  
Roberto Ferrari: 这是一项注册研究，旨在观察在冠状动脉疾病门诊患者对治疗的需求和治疗方法。这项全球性的注册研究将纳入至少3万例患者，随访期限为5年。我们认识到在欧洲和全球，缺乏足够的有关这类患者在真实临床情景中的治疗现状的数据。我们确实有临床试验数据，但调查对象通常是住院病人并且预先指定患者治疗方式，因此临床试验通常会有偏倚。我们希望了解真实的情况。这是欧洲心脏病学学会（ESC）向世界提供真实临床情景数据的新策略，也是与中华医学会心血管病学分会（CSC）的一项合作。未来，ESC
会尝试开展两三个双方都认为很重要的合作项目。
