fractional flow reserve

Abbreviation: FFR
The ratio of the blood pressure in the furthest reaches of a coronary artery divided by the blood pressure in the aorta. The ratio is determined when the arteries are maximally vasodilated. The FFR determines the flow-limiting significance of a coronary artery stenosis. When the pressure in the distal portion of a healthy coronary artery is equal to the pressure in the aorta, the FFR is 1.0. Arteries with FFR less than 0.75 have large enough obstructions to cause myocardial ischemia.
