Diagnostic Performance of Diastolic Hyperemia-Free Ratio Compared With Invasive Fractional Flow Reserve for Evaluation of Coronary Artery Disease
Percutaneous coronary intervention guided by invasive fractional flow reserve (FFR) improves cardiovascular outcomes compared with coronary angiography alone and compared with medical therapy in patients with stable ischemic heart disease.1,2 FFR-guided revascularization has been incorporated into American and European practice guidelines.3,4 However, the need for adenosine to achieve maximum hyperemia limits FFR because of patient discomfort, increased cost, increased procedural time, and variability in the time to achieve maximal hyperemia.
