01 Fractional Flow Reserve (FFR) is a medical term that describes the ratio of blood flow through a narrowed or blocked coronary artery to the maximum possible blood flow through that artery. It assesses the functional significance of coronary stenosis, which is a narrowing or obstruction of the coronary arteries that supply blood to the heart muscle. FFR is calculated by dividing the blood flow through the narrowed or blocked artery by the maximum blood flow through that artery, which is typically measured during a cardiac catheterization procedure. The resulting value is expressed as a percentage, with a higher value indicating a more severe stenosis.FFR is used to determine the severity of coronary artery disease and to inform treatment decisions. It is especially useful for determining whether a patient with coronary artery disease needs angioplasty or bypass surgery. A low FFR value indicates that the narrowed or blocked artery is not significantly reducing blood flow to the heart muscle, and thus, intervention may not be necessary. A high FFR value, on the other hand, indicates that a narrowed or blocked artery is significantly reducing blood flow to the heart muscle, necessitating intervention to improve blood flow and lower the risk of a heart attack or other complications.
