Long-Term and Temporal Relationships Between Post-Stent Fractional Flow Reserve and Clinical Outcomes
- Registry-based cohort study
- international registry
Authors' conclusion
The prognostic impact of post-PCI FFR on TVF persisted over a 5-year follow-up period, but it was more prominent during the first 3 years after PCI. In contrast, its impact on TVR in the nonstented segments was sustained throughout the entire 5-year follow-up period.
Study context
- Population
- Patients after angiographically successful drug-eluting stent implantation with post-PCI fractional flow reserve (FFR) measurement and 5-year follow-upcompleted 5-year follow-up
- Participants
- 2,128 patients
- Exposure
- Low vs high post-PCI FFR
- Outcome
- Target vessel failure (TVF) (cardiac death, target vessel MI, target vessel revascularization (TVR))
- Follow-up
- 5 years
