QFR shows high correlation, diagnostic accuracy and discriminant function with FFR

In the field of coronary revascularization, where identifying reversible myocardial ischemia is paramount, FFR and iFR are standard but underutilized due to various limitations. QFR, an angiography-derived method, emerges as a potential game-changer, providing functional assessment without additional wires or hyperemic agents and showcasing a shorter measurement time than invasive methods. In conclusion, the study, aligning with ongoing trials, suggests that a QFR-guided strategy could simplify, enhance safety, and cost-effectively guide revascularization decisions. Furthermore, the findings position QFR as a promising tool to boost the adoption of physiology-based revascularization in routine clinical practice.
