and, without the proper precautions,ejection.The numerous belts and harnesses of modern coasters
Now, in healthy macaques, like in healthy people,ejection fractions are about 65 percent.After a heart attack, ejection fraction drops down to about 40 percent,
when we scan them a month later,we see that ejection fraction is unchanged,because the heart, of course, doesn't spontaneously recover.
we went to something that's called "left ventricular ejection fraction."Ejection fraction is simply the amount of bloodthat is squeezed out of the chamber of the heart
If we extend these studies out to three months,we get a full 22-point gain in ejection fraction.(Applause)
