Key Takeaway
Note that angiography-derived FFR shows no significant difference in MACE compared to wire-based FFR.

This meta-analysis evaluated the clinical and procedural outcomes of angiography-derived FFR compared to wire-based FFR in 6,542 patients undergoing coronary revascularization. The study aimed to determine if angiography-derived FFR provides equivalent clinical safety and efficacy to the standard wire-based method.

The analysis found no significant difference in major adverse cardiovascular events (MACE) between the two methods (RR 1.07; 95%CI 0.91-1.27). However, patients in the angiography-derived FFR group had higher patient-level PCI rates (RR 1.24; 95%CI 1.15-1.33) and higher lesion-level PCI rates (RR 1.24; 95%CI 1.18-1.31). Procedural times were shorter in the angiography-derived FFR group (MD -4.09 min; 95%CI -5.76 to -2.43).

Several limitations were noted, including insufficient sample size for most hard clinical endpoints and low certainty for the stent thrombosis outcome. Clinical outcomes were generally rated as moderate certainty, while procedural outcomes were rated as high certainty. These findings suggest that while angiography-derived FFR may offer procedural efficiencies and higher PCI rates, it does not appear to alter the primary clinical outcomes of MACE compared to wire-based FFR.

How this fits prior evidence

This meta-analysis addresses a gap in comparing angiography-derived FFR to wire-based FFR for coronary revascularization. While previous coverage noted that systematic screening for silent myocardial ischemia does not reduce MACE or mortality in asymptomatic diabetic patients, this study specifically evaluates the impact of FFR measurement techniques on MACE in patients undergoing revascularization. The finding of no significant difference in MACE (RR 1.07) provides a specific comparison of measurement modalities in the setting of coronary artery disease.

Researchers looked at 6,542 patients undergoing coronary revascularization to compare two methods for measuring blood flow: angiography-derived FFR and wire-based FFR. The study aimed to see if one method led to better outcomes for patients with coronary artery disease.

The results showed no significant difference between the two methods regarding major adverse cardiovascular events. However, patients in the angiography-derived FFR group were more likely to undergo a procedure called PCI. The study also noted that the angiography-derived method resulted in shorter procedural times.

Because the study was a meta-analysis, it is important to note that some findings had lower certainty. For example, the data on stent thrombosis was not very certain due to a small sample size. While the angiography-derived method may speed up the procedure and increase PCI rates, it did not change the primary safety outcomes for the patients.

What this means for you:
Angiography-derived FFR shows no difference in major heart events but may lead to more procedures and shorter times.

Common questions

Does the type of FFR measurement affect heart safety?

The study of 6,542 patients found no significant difference in major adverse cardiovascular events between angiography-derived FFR and wire-based FFR. This means both methods showed similar results regarding primary safety outcomes for patients with coronary artery disease.

Are there differences in procedure time or rates?

Patients in the angiography-derived FFR group had shorter procedural times, averaging about 4 minutes less. This group also showed a higher rate of undergoing PCI at both the patient and lesion levels compared to those using wire-based FFR.

Is the data on stent thrombosis reliable?

The evidence for stent thrombosis was rated as low certainty. This was because the sample size was not large enough to provide a clear conclusion for that specific outcome. You should talk to your doctor about how these findings apply to your specific care.

BackgroundInvasive pressure-wire-based fractional flow reserve (FFR) is the reference standard for physiology-guided coronary revascularization, yet it requires pressure-wire equipment and adenosine-induced hyperemia. Angiography-derived FFR enables functional assessment solely from coronary angiograms, while quantitative pooled evidence from patient-level randomized controlled trials (RCTs) remains limited.MethodsWe searched PubMed, Cochrane Library, Embase and Web of Science Core Collection for eligible RCTs comparing angiography-derived FFR-guided versus wire-based FFR-guided revascularization. The primary endpoint was major adverse cardiovascular events (MACE). Pooled risk ratios or mean differences with 95% confidence intervals were calculated. GRADE assessment and trial sequential analysis (TSA) were performed, and publication bias was evaluated by funnel-plot inspection.ResultsFour RCTs involving 6,542 participants were included. No significant difference in MACE was observed between groups (RR 1.07, 95%CI 0.91-1.27). All-cause mortality, cardiac mortality, recurrent myocardial infarction, unplanned revascularization and stent thrombosis were also comparable. Angiography-derived FFR was associated with higher patients-level PCI rate (RR 1.24, 95%CI 1.15-1.33), lesion-level PCI rate (RR 1.24, 95%CI 1.18-1.31) and shorter procedural time (MD −4.09 min, 95%CI −5.76 to −2.43). TSA showed insufficient sample size for most hard clinical endpoints. GRADE certainty varied across endpoints, procedural outcomes were rated high-certainty, while most clinical outcomes were of moderate certainty and stent thrombosis of low certainty.ConclusionsRelative to wire-based FFR, angiography-derived FFR showed no statistically significant difference in ischaemic-driven clinical outcomes and procedural duration. However, it may increase the likelihood of undergoing PCI. Further large-scale trials with extended follow-up are needed to clarify the long-term implications of this revascularization pattern.Systematic Review Registrationhttps://www.crd.york.ac.uk/PROSPERO/, CRD420261479620.
