Discover the future of STEMI management with “QFR Insights in STEMI: enhancing emergency treatment strategies” by prof. Eric van Belle

We are happy to announce that we will host another Medis QFR® Academy session, this session will feature Prof. Eric Van Belle, esteemed Head of Interventional Cardiology at University Hospital of Lille, France. He will guide us through the intricacies of using QFR in the context of ST-elevated myocardial infarction (STEMI). This session will illuminate the pivotal role of QFR in distinguishing between culprit and non-culprit lesions, using two detailed clinical case studies as a backdrop for discussion. This session will be moderated by Dr. Ignacio J Amat Santos From University of Valladolid Medical Centre in Spain.

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.
