An FFR lower than 0.75-0.80 is generally considered to be associated with myocardial ischemia.7. FFR < 0.75 was validated against the 3 gold standard tests to correlate with ischemia with 100% specificity. FFR between 0.75 and 0.80 may indicate ischemia. FFR > 0.80 is highly likely to be non‑ischemic.
