Application value of CCTA-AI combined with FFR-CT in the diagnosis of coronary artery stenosis lesions
Objective To evaluate the impact of cardiac computer tomography angiography(CCTA)and artificial intelli-gence(AI)combined with fractional flow reserve(FFR-CT)on the diagnosis of coronary artery stenosis lesions.Methods 80 patients with suspected coronary artery stenosis who received treatment at Nanyang Central Hospital from January 2022 to February 2023 were selected as observation subjects.All patients underwent CCTA and coronary angiography(CAG)exami-nation,with an interval of 14 days.The images of CCTA were automatically reconstructed and calculated by AI software,and FFR-CT values were calculated at the same time.The sensitivity,specificity,accuracy,positive predictive value,and nega-tive predictive values of AI assisted cardiac computed tomography(CCTA-AI)combined with FFR-CT diagnosis were calcu-lated.Results 80 patients were diagnosed through CAG examination,and 72 patients had coronary artery stenosis lesions,accounting for 90%;8 patients had non coronary artery stenosis lesions,accounting for 10%.The sensitivity,specificity,positive predictive value,negative predictive value,accuracy,and AUC value of CCTA-AI combined with FFR-CT examina-tion were higher than those of CCTA-AI and FFR-CT alone,and difference was statistically significant(P<0.05).Conclu-sion CCTA-AI combined with FFR-CT in the diagnosis of coronary artery stenosis has high diagnostic efficacy,and its sen-sitivity and specificity are significantly improved.
