WebFractional flow reserve, also known as FFR, is a measurement of how well blood can flow through the coronary arteries. These arteries bring oxygen-rich blood to the heart to be pumped throughout the rest of the body. Narrowing or blockages in these arteries is called coronary artery disease. This can lead to a heart attack without treatment. WebFractional flow reserve (FFR) is a physiological index of the severity of a stenosis in an epicardial coronary artery, based on the pressure differential across the stenosis. Clinicians are increasingly relying on this method because it is independent of baseline flow, relatively simple, and cost effective. The accurate measurement of FFR is predicated on maximal …
