FFR

Abbreviation for:
field-free region (see there)

reserve

(re-zerv') [L. reservare, to keep back]
1. Something held back for future use.
2. Self-control of one's feelings and thoughts.

alkali reserve

Alkaline reserve.

alkaline reserve

The amount of base in the blood, principally bicarbonates, available for neutralization of fixed acids (acetoacetate, ß-hydroxybutyrate, and lactate). A fall in alkaline reserve is called acidosis; a rise, alkalosis.
Synonym: alkali reserve

cardiac reserve

The ability of the heart to increase cardiac output to meet the needs of increased energy output.

coronary flow reserve

The ratio of the blood flow in the coronary arteries when they are at rest to their blood flow when they are maximally stimulated or dilated.
See: coronary blood flow

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.

ovarian reserve

The number of remaining oocytes or follicles in the ovaries. The number typically falls with increasing age. It also declines as a result of some types of chemotherapy. Women with very limited ovarian reserves may have difficulty conceiving a child without assisted reproductive techniques.

fractional flow reserve

Abbreviation: FFR

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.

Using data from DEFINE-FLAIR, a study that compared iFR to FFR and reported that the different technologies performed similarly for clinical outcomes, with iFR actually resulting in fewer symptoms for patients before, during and after the procedure for their cost analysis, Patel and colleagues found that the average cost of the catheterization procedure was lower in the iFR group than in the FFR group.
