Predictors of discordance between fractional flow reserve and instantaneous wave-free ratio in the real world

ConclusionOur study shows that almost a quarter of lesions show discordance for FFR and iFR with a female preponderance. The four groups classified according to FFR and iFR are characterized by differences in clinical characteristics and predictors of discordance. The lesions with discordant FFR and iFR may have a different pathophysiology which warrants further investigation.
