In contrast, fractional flow reserve (FFR) is a physiologic measure of coronary stenosis expressing the amount of coronary flow still attainable despite the presence of a stenosis, but it requires an invasive procedure. Also, fractional flow reserve (FFR) can detect pressure decrease at the bridge distally.
Ejection fraction is a term that describes the ability of the heart to pump out blood, which is compromised in a person with congestive heart failure. Essentially, ejection fraction is a measurement of the relative strength or weakness of a person's heart. The lower the ejection fraction, the more difficulty the heart has in pumping blood from the left ventricle. A normal ejection fraction may be in the range of 50-75%. Anything below 50% is generally indicative of chronic, or congestive, heart failure.
