Brief Summary:
The aim of this study was to investigate the accuracy of quantitative flow ratio QFR for predicting fractional flow reserve FFR 080 in an independent core laboratory
Detailed Description:
FFR is an invasive physiological index used to define coronary stenosis that causes ischemia Several studies have suggested that FFR-based percutaneous coronary intervention PCI can reduce adverse clinical outcomes compared to angiography-guided PCI Although FFR is highly recommended in current guidelines it is underused in real-world practice QFR is a method for evaluating fractional flow reserve FFR without the use of an invasive coronary pressure wire or pharmacological hyperemic agent
The aims of this study were
1 To investigate diagnostic accuracy of angiography-based QFR for hemodynamic assessment of coronary artery stenosis compared to pressure wire-based FFR
2 To compare the diagnostic performance of QFR versus diameter stenosis DS in identifying physiologically significant coronary artery disease CAD using FFR as the reference standard
3 To identify factors affecting QFR accuracy
4 To compare the coronary CT data with QFR
