  • Long-term follow-up of the FAVOR III China randomised controlled trial
  • multicentre
  • sham-controlled

Authors' conclusion

Compared with angiography guidance, QFR-guided strategy improved 5-year clinical outcomes, with benefits primarily achieved within the first 2 years.

Study context

Population
Patients with ≥1 angiographically intermediate coronary lesion (50%-90% diameter stenosis) in a vessel ≥2.5 mm diameter
Comparison
Quantitative flow ratio (QFR)-guided percutaneous coronary intervention (PCI) vs angiography-guided PCI
