Fractional Flow Reserve

Fractional Flow Reserve (FFR) is a diagnostic procedure used to assess the severity of blood flow restriction in coronary arteries. It measures the pressure differences across a narrowed artery during a physiological state, typically induced by a vasodilator like adenosine. An FFR value of 1.0 indicates normal blood flow, while values below 0.80 suggest significant ischemia, meaning the artery is restricting blood flow enough to potentially cause angina or heart damage. FFR is often used in conjunction with coronary angiography to guide treatment decisions, helping to determine whether a patient would benefit from interventions such as angioplasty or stenting. It enhances clinical decision-making by providing a more accurate assessment of the functional significance of coronary lesions.
