摘　　要：目的分析宝石CT与超声心动图(ECHO)评估冠状动脉狭窄的价值。方法选取我院2017年12月至2018年11月收治的110例疑似冠心病患者为研究对象,所有患者均行宝石CT冠状动脉成像(CTA)、ECHO检查,以CAG检查结果为"金标准",分析宝石CT与ECHO对冠状动脉狭窄的评估价值。结果宝石CT对冠状动脉阳性病变诊断灵敏度、特异度、准确度、阳性预测值、阴性预测值分别为88.57%、97.13%、95.66%、86.45%、97.63%。ECHO对冠状动脉阳性病变诊断灵敏度、特异度、准确度、阳性预测值、阴性预测值分别为82.04%、94.68%、92.52%、76.14%、96.23%。宝石CT对冠状动脉病变诊断特异度、准确度、阳性预测值和阴性预测值均显著高于ECHO(P<0.05),对冠状动脉狭窄程度检出结果优于ECHO(P<0.05)。结论宝石CT能够清楚显示患者冠脉病变情况,对冠状动脉狭窄诊断效能优于ECHO,可将宝石CT作为临床诊断冠状动脉狭窄的辅助方法。Objective To analyze the value of gemstone CT and echocardiography(ECHO)in evaluating coronary artery stenosis.Methods A total of 110 patients suspected of coronary heart disease admitted to our hospital from December 2017 to November 2018 were selected for the study.All patients were given gemstone CT coronary angiography(CTA)and ECHO examination.The CAG examination results were used as a gold standard to evaluate the practical value of gemstone CT and ECHO on coronary artery stenosis.Results The sensitivity,specificity,accuracy,positive predictive value,and negative predictive value of gemstone CT for coronary artery-positive lesions were 88.57%,97.13%,95.66%,86.45%,and 97.63%,respectively.The sensitivity,specificity,accuracy,positive predictive value,and negative predictive value of ECHO for coronary artery-positive lesions were 82.04%,94.68%,92.52%,76.14%,and 96.23%,respectively.The specificity,accuracy,positive predictive value,and negative predictive value of gemstone CT for coronary artery lesions were significantly higher than those of ECHO(P<0.05),and the detection results of coronary artery stenosis were better than those of ECHO(P<0.05).Conclusion Gemstone CT can clearly show the coronary artery lesions in patients,and it has better diagnostic efficacy than ECHO on coronary artery stenosis.Moreover,Gemstone CT can be used as an auxiliary method for clinical diagnosis of coronary artery stenosis.
