The diagnostic value of a hybrid quantitative flow ratio–FFR strategy for ischemia-causing stenosis in patients with unstable angina and its impact on revascularization strategy

2024-07-16

Abstract excerpt

<title>Abstract</title> <p>Quantitative flow fraction (QFR) is a functional test without a guide wire based on coronary angiography. In this study, flow reserve fraction (FFR) was used as the reference standard to verify the diagnostic value of QFR in patients with unstable angina pectoris with critical coronary artery disease (coronary artery stenosis degree of 40%-70%) functional stenosis, and to evaluate the e...
