Diagnostic Accuracy of Angiography-Based Quantitative Flow Ratio Measurements for Online Assessment of Coronary Stenosis

Xu et al. (Tue,) conducted a observational in Coronary stenosis (n=308). Quantitative flow ratio (QFR) vs. Quantitative coronary angiography (QCA) and wire-based FFR was evaluated on Diagnostic accuracy of QFR exceeding a lower 95% CI boundary of 75% (95% CI 88.9% to 95.1%, p=< 0.001). Online quantitative flow ratio (QFR) achieved a patient-level diagnostic accuracy of 92.4% (95% CI: 88.9% to 95.1%; p<0.001) for identifying hemodynamically significant coronary stenosis.
