Background: Fractional flow reserve (FFR) is a method which is used to identify the angiographically intermediate lesions requiring revascularization. However, physiological importance and clinical usability of delta (Delta) FFR, the difference between FFR in baseline conditions (FFRbase, resting) and after adenosine administration (FFRmin, hyperemic), is currently unknown. We aimed to investigate whether Delta FFR may be helpful in the identification of the lesion severity and predictability of long term prognosis.
