Fractional flow reserve (FFR), an index of the hemodynamic severity of coronary stenoses, is derived from invasive measurements and requires a pressure-monitoring guidewire and hyperemic stimulus. Angiography-derived FFR measurements (FFR angio ) may have several advantages. The aim of this study is to assess the diagnostic performance and interobserver reproducibility of FFR angio in patients with stable coronary artery disease.
