Fractional flow reserve vs angiography to guide percutaneous coronary intervention: an individual patient data meta-analysis
Pooled resultResult — go to the resultHazard ratio .80 95% CI .64-.99Authors' conclusion
Fractional flow reserve-guided PCI was associated with reduced major adverse events in patients with CCS and NSTE-ACS due mainly to fewer peri-procedural MIs, with no differences in mortality or MACE beyond 30 days.
Study context
- Population
- Intermediate coronary lesions in chronic coronary syndrome or non-culprit vessels in non-ST-elevation acute coronary syndromes (NSTE-ACS)

- FFRn = 1,252
- Angiographyn = 1,241reference
- Outcome
- MACE:
- All-cause death
- MI
- Repeat revascularization
- Follow-up
- 1 year
