Ask the doctors. You often publish references in Heart Advisor to medical journal articles and I've started trying to read some of them in my doctor's waiting room.  One surprise is that they (and you) often refer to "recent" research. But I've learned that some of the "recent" findings took years to get published. I would think that people who discover new ways to save lives would want to tell the world as soon as possible.
