Leg pain can have less obvious causes, such as peripheral artery disease.
Cardiopulmonary resuscitation (CPR) is an emergency procedure that is performed on people who are suffering from cardiac arrest. The purpose of CPR is to provide a flow of oxygenated blood to the brain until other procedures can be performed to restore the person's heartbeat and breathing.
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.
