Comparative study of FFR and dPR

Not Applicable

• Conditions: Ischemic heart Disease; Ischemic heart disease

• Registration Number: JPRN-jRCTs042200015
• Lead Sponsor: Tanaka Akihito

Brief Summary

We showed dPR was highly correlated with FFR, and diagnostic discordance was observed in only 11% of the patients. Our results might support the wide availability of dPR in real-world settings; however, we need to consider that several factors may cause diagnostic disagreement between FFR and dPR, including the evaluated lesion location and medication for hyperemia.
