This study is a prospective and single-center trial in China.It intends to enroll 216 patients with coronary artery disease whose coronary artery is determined to be 30-90% stenosis after coronary CT scan. CT image data will be imported for CT-QFR detection and undergo coronary angiography within 30 days. Quantitative analysis of coronary angiography (QCA) was performed with the degree of coronary stenosis. FFR and QFR were detected during the operation. Use FFR as a reference standard to verify the diagnostic performance of CT-QFR and QFR. The primary endpoint is the diagnostic accuracy of CT-QFR in identifying hemodynamically significant coronary stenosis with FFR as the reference standard. Major secondary endpoint is the non-inferiority of CT-QFR compared with QFR in the patients without extensively calcified lesions. The completion of the project will provide patients with a practical non-invasive assessment method of coronary heart disease which provides the best treatment strategy.
