Pump Up the Volume (1990) Teenage angst finds a new voice in this drama. By day, Mark Hunter (Christian Slater) is a quiet, studious student at an ordinary suburban high school in Arizona.
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.
Fractional flow reserve. Fractional flow reserve (FFR) is a technique used in coronary catheterization to measure pressure differences across a coronary artery stenosis (narrowing, usually due to atherosclerosis) to determine the likelihood that the stenosis impedes oxygen delivery to the heart muscle (myocardial ischemia).
