摘　　要：【目的】探讨CT冠状动脉造影血流储备分数(FFRCT)在心脏病变中的诊断价值。【方法】选择两院收治的75例心脏病患者为研究对象,通过冠状动脉CT造影检查(CCTA),冠状动脉造影检查(CAG)以及有创血流储备分数(FFR)检查获得患者相应的图像以及数据,建立FFRCT模型,分析FFRCT技术在冠心病患者中分别以患者为单位和以血管支数为单位检测中的敏感性、特异性以及准确性等,同时探讨FFRCT测定值与有创FFR测定值的相关性。【结果】本组75例患者共发现病变血管100支,其中左前降支病变58例,左回旋支病变16例,右冠状动脉26例。以有创FFR为标准,以患者为单位FFRCT检测结果的特异性、敏感性、阳性预测值、阴性预测值、准确性以及κ值分别为100.0%、87.6%、100.0%、50.0%、89.7%、0.62;以血管支数为单位FFRCT检测结果的特异性、敏感性、阳性预测值、阴性预测值、准确性以及κ值分别为100.0%、65.3%、100.0%、50.0%、76.4%、0.51;以患者为单位、以血管支数为单位,FFR与FFRCT均呈正相关,具有良好的一致性(r=0.794、0.725,P<0.05)。【结论】FFRCT技术在CAD患者冠状动脉检测中具有较高的应用价值,临床可以推广FFRCT技术,为患者合理选择诊疗策略提供参考。【Objective】To investigate the diagnostic value of CT coronary angiography blood flow reserve fraction(FFRCT)in heart disease.【Methods】A total of 75 patients with heart disease in our Hospital were selected as the research objects.The corresponding images and data were obtained by coronary CT angiography(CCTA),coronary angiography(CAG)and invasive blood flow reserve fraction(FFR).The FFRCT model was established to analyze the sensitivity,specificity and accuracy of FFRCT in the detection of blood vessel as the unit and the number of vessels in coronary heart disease.The correlation between FFRCT and invasive FFR was also investigated.【Results】A total of 100 lesions were found in 75 patients,including 58 left anterior descending lesions,16 left circumflex lesions,and 26 right coronary arteries.Based on the invasive FFR,the specificity,sensitivity,positive predictive value,negative predictive value,accuracy andκof the FFRCT test results were 100.0%,87.6%,100.0%,50.0%,89.7%and 0.62,respectively.The specificity,sensitivity,positive predictive value,negative predictive value,accuracy andκof the FFRCT test results in terms of vessel count were 100.0%,65.3%,100.0%,50.0%,76.4%and 0.51,respectively.In units of patients and blood vessels,FFR and FFRCT were positively correlated with good consistency(r=0.794、0.725,P<0.05).【Conclusion】FFRCT technology has a high value in the detection of coronary artery disease in patients with coronary heart disease.The clinical application of FFRCT technology should be used to rationally select the diagnosis and treatment strategy for patients.
