International Circulation: I’m here with Professor Jack Lewin. I’d like to thank you for joining us today， professor. It is a great honor having you here. At first I’d like to ask you the NCDR provides the most comprehensive cardiovascular data registry， representing a very large patient population and millions of records in the US. And this makes significant impact on clinical practice. So could you comment on the recent research projects of NCDR that you think are the most influential perhaps or most important something that we should know about?
