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.
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.
