Sex Differences in Fractional Flow Reserve– or Intravascular Ultrasound–Guided Percutaneous Coronary Intervention

JACC Cardiovasc IntervPublished

  • Secondary analysis of the FLAVOUR randomised trial

Authors' conclusion

In cases of intermediate stenosis, despite receiving fewer interventions, women had more favorable outcomes than men. The use of FFR led to a lower PCI rate but had a similar prognostic value compared with IVUS in both women and men.

Study context

Population
Patients with intermediate coronary stenosis in the FLAVOUR trial (fractional flow reserve (FFR)- vs IVUS-guided percutaneous coronary intervention (PCI))30% women
Participants
1,619 patients
Comparison
Women vs men, by FFR- or IVUS-guided PCI strategy
Primary endpoint
TVF (cardiac death, target vessel MI, target vessel revascularization)
Follow-up
24 months

Primary result

As reported in the abstract

TVF

Further findings

TVF in patients with deferral of PCI (subgroup)

PCI rate, women vs men

Lower PCI rate in women than men (40.8% vs 47.9%), mainly with FFR guidance
P = 0.008

Target vessel failure (TVF) in patients who underwent PCI (subgroup)

Lower TVF in women vs men not observed among patients who underwent PCI

Clinical outcomes, FFR- vs IVUS-guided, by sex

No differences between FFR- and IVUS-guided strategies in women or men
