Authors' conclusion

A higher composite lesion risk score was associated with increased PCI rates and TVF risk after AngioFFR- or IVUS-guided treatment. AngioFFR guidance was associated with lower PCI rates in low-risk lesions, whereas IVUS guidance may yield more favorable outcomes in high-risk lesions.

Study context

Population
Patients with ≥50% stenosis randomized to AngioFFR- or IVUS-guided PCI
Participants
1,726 patients
Comparison
AngioFFR vs IVUS
  • AngioFFRn = 884
  • IVUSn = 842
Primary endpoint
Target vessel failure:
  • TVF: cardiac death
  • Target vessel myocardial infarction
  • Target vessel revascularization
Follow-up
median 12-month follow-up
