Resting Pd/Pa showed poor agreement with hyper-emic FFR assessed with use of a monorail pressure microcatheter. However, resting Pd/Pa of 0.96 or greater had excellent sensitivity and NPV to predict normal hyperemic FFR, and resting Pd/Pa of 0.82 or less had excellent specificity and PPV to predict abnormal hyperemic FFR.
