When the problem is in the blood vessels that carry blood to any part of the body other than the heart, it is called peripheral vascular disease (PVD). Itâs also important to note that people who have blockages in the arteries in their legs, feet and kidneys are at greater risk for heart attack and stroke.
The Physicians' Desk Reference (PDR) is a commercially published compilation of manufacturers' prescribing information (package insert) on prescription drugs, updated annually.n 1984, Paul C. Kranz and Michael Grondin travelled to Oradell, New Jersey, and presented to Medical Economics (then-publisher of the PDR) a prototype developed by Grondin on a TI 99/4A computer of how a digital copy of the PDR would work and benefit clinicians.
FloWireÂ® Doppler Guide Wire image, courtesy Volcano Corporation. What is FFR? Fractional Flow Reserve, or FFR, is a guide wire-based procedure that can accurately measure blood pressure and flow through a specific part of the coronary artery. FFR is done through a standard diagnostic catheter at the time of a coronary angiogram (a.k.a. cardiac catheterization). The measurement of Fractional Flow Reserve has been shown useful in assessing whether or not to perform angioplasty or stenting on intermediate blockages. 1  The point of opening up narrowings or blockages in the coronary arteries is to increase blood flow to the heart.
