Distribution of lowest FFR value per patient (n = 126). Ischemia was evaluated on a patient basis, an FFR ≤ 0.8 or angiographic high-grade stenosis (≥ 90% DS) was used to indicate the presence of a functionally significant stenosis. Per patient, the lowest FFR value is depicted, unless this concerned an FFR > 0.8, and a high-grade stenosis on ICA (≥ 90% DS) was present in another vessel, then this was scored as “high-grade stenosis on ICA”, and FFR value of that patient is not depicted. DS, degree of stenosis; FFR, fractional flow reserve; ICA, invasive coronary angiography
